Battlefield 1

Battlefield 1 is a first-person shooter developed by Swedish game developer DICE and published by Electronic Arts, and a main series installment in the popular Battlefield series. It is set in World War 1, with players taking on the role of soldiers in the trenches or controlling vehicles from tanks and early fighter planes to armored trains and Zeppelins.
Four DLCs are released: They Shall Not Pass, focusing on the French Republic in WWI; In the Name of the Tsar, focusing on the Russian Empire and the Russian Civil War; Turning Tides, focusing on Naval and Amphibious Campaigns in WWI; and Apocalypse, a DLC with the thematic focus of "the most infamous and grittiest battles of WWI". Other contents are added in sporadic content drop updates.
For the actual first entry in the Battlefield series, see Battlefield: 1942.
For the first WWI Battlefield game (not part of the Battlefield series due to it being a community-made mod), see Battlefield: 1918.
__TOC__
=Overview=
The game's class system is altered somewhat from previous incarnations. The Assault class is close to the anti-tank classes of previous games, using heavy anti-vehicle weapons and submachine guns or shotguns, the Medic class is a general-purpose combatant with automatic or semi-automatic rifles (grouped under the "self-loading rifle" moniker), the Support class uses machine guns, and the Scout class uses bolt-action (plus one lever-action, one single-shot, and one semi-automatic converted bolt-action) rifles (in-game these are grouped together as "Single-Action Rifles").
There are also new vehicle-using "Tanker" and "Pilot" classes, both using pistol-carbines (or a sawed-off shotgun) and the former having a repair tool; these are automatically assigned when the player chooses to spawn in a fresh armored vehicle, naval destroyer, or airplane. The Tanker/Pilot primary weapons became available to the Assault and Support classes in June 2018 CTE, the two classes receiving access to some of the pistol carbine armaments. An additional vehicle class is the Cavalry, whose kit is provided when the player rides on a horse. The Cavalry primarily use melee weapons, but also have a Winchester Model 1895 for ranged effectiveness.
Additional to the standard classes are Elite Classes, classes whose equipment kits are found on maps at strategic locations and can be picked up by players. They are a successor to the often underpowered Battle Pickups in Battlefield 4. There are four Elite Classes: Flame Trooper, Sentry, Tank Hunter, and Trench Raider (who was added in the They Shall Not Pass DLC). The Flame Trooper wields the Wechselapparat M1917 flamethrower, the Sentry use either the MG 08/15 light machine gun or the Villar Perosa double-barreled submachine gun, the Tank Hunter wields the Mauser 1918 Tankgewehr, and the Trench Raider uses a trench raiding club as a primary weapon. All Elite Classes have additional equipment in addition to their primary weapons, and all wear body armor (of varying levels, the Sentry being the toughest) that grant them extra damage resistance. Flame Troopers appear in singleplayer campaign as enemies, while the Sentry kit is used by the player character Luca in the "Avanti Savoia!" campaign War Story.
Clip-loaded weapons are all portrayed with detailed clip-by-clip reload animations and single-round reload animations, much like Red Orchestra 2: Heroes of Stalingrad, and rifles often have a reload detail with the player's left hand covering the magazine when opening the action to stop the rounds from flying out. To prevent a scope attachment from blocking the magazine, all weapon scopes are side-mounted, even when real examples of the weapon had centrally-mounted scopes (e.g. on the scoped Gewehr 98). Not stopping with clip-loaded weapons, many other weapons in the game (especially DLC weapons) feature very unusual dynamic reloads seen in very few games, detailed in their individual sections.
Battlefield 1 uses a system of weapon variants in place of weapon modifications like in previous Battlefield games. Instead of letting players freely customize their weapon attachments, each weapon has a number of variants each with pre-allocated attachments. The only attachments that can be customized by the player are Ironsights, Bayonets, Magnification range and in the case of automatic weapons, adjusting the direction of recoil control (for some weapons, this changes the model of the muzzle device; included styles are typically a Madsen-style flash hider by default, with a Cutts compensator or no device for the left/right options). Below is a list of common names referring to each variant.
* Factory - Describes the weapon being lightweight, having fast movement speeds and ADS times. No attachments installed. 
* Trench - Refers to the weapon having improved hip fire or close range abilities. Typically equipped with a foregrip or, in some some unique cases such as the Winchester 1895, a caliber change. 
* Storm - Refers to the weapon having improved ADS accuracy, even when moving. Formerly called "Light Infantry" in the Alpha and Open Beta versions. 
* Optical - Attaches an optical Lens Sight for greater ADS accuracy. On some weapons, a vertical foregrip is also installed. The Lens Sight is based on the experimental Gibbs Magnifying Sights, tested by the British in small quantities and only on the Lee-Enfield rifles of the era.
* Marksman - Attaches a medium range optical sight with a magnification range between 2.5x and 5x as well as bipod. The medium range optical sight in BF1 is based on the Warner & Swasey Model 1913 Prismatic Musket Scope.
* Sniper - Applies to Scout rifles, equips them with a long range optical sight with magnification ranges between 5x and 10x as well as a bipod for stabilized accuracy. Some medic rifles also support this variant, who get a weaker powered scope. The long range optical sight is based on the PPCo scope, while the lower-powered on is apparently the same scope just with the front and rear ends removed.
* Backbored - Applies to shotguns; reduces recoil but increases damage drop-off. The name refers to a modification to the weapon's barrel where the barrel interior diameter is increased with tools. This lowers the barrel pressure and shortens the shot string, translating to reduced recoil in-game.
* Hunter - Applies to shotguns; attaches a choke tightening shot spread for greater effective range. 
* Slug - Applies to shotguns that fire a single powerful slug instead of buckshot. Also applies the Lens Sight, excluding the Model 1900. Formerly called the "Heavy" variant in the Open Beta. 
* Extended - Extends the weapon's magazine; only the Browning Auto-5 and Remington Model 8 have this variant.
* Low Weight - Applies to machine guns; identical to the "Factory" variant, having no attachments (other than a bipod), but possessing improved movement speed and ADS times. 
* Telescopic - Applies to machine guns; equipped with a bipod and a medium-range optical sight with a magnification range between 2.5x and 5x. 
* Suppressive - Applies to machine guns; increases the weapon's capacity, adds a bipod, and attaches a unique optical sight exclusive to Suppressive variants. The optical sight is based on the German Zielfernrohr 12 (ZF 12) sight.
* Infantry - Applies to Scout weapons; only has iron sights, rather than optics.
* Carbine - Applies to Scout weapons; removes the medium- or long-range telescopic sight in place of a short-range "Dot" sight with increased movement, ADS times and slightly better hip fire accuracy. 
* Defensive - Applies to the Standschütze Hellriegel 1915 and Perino M1908. Adds a "Lens" sight to both, a bipod and extended magazine to the Hellriegel, and a tripod to the Perino.
* Sweeper - Only available to the Winchester Model 1907 and the M97 Trench Gun. In case of the 1907, it adds a foregrip and select-fire functionality, improving hip fire and close-range effectiveness, while the M97 shotgun gains a duckbill choke for greater horizontal shot dispersion, and fires more pellets per shot, with reduced damage per pellet. 
* Experimental - Applies only to the MP18, Steyr M.12/P.16, and Springfield M1903. The MP 18 is locked to a three-round burst and gets a short-range lens sight and a 30-round stick mag; the Steyr M.12 gets locked to a faster two-round burst and receives lens sight; the M1903 receives a Pedersen device.
* Patrol - A variant category added post-launch in the May 2018 "Weapons Crate" update. Applies to the Arisaka Type 38, M1917 Trench Carbine, and Carcano 1891 Carbine, equipped with Medic-styled medium-powered scopes.
In addition, taking a page from Battlefield Hardline, each of the classes have their own class-exclusive sidearms. However, there are also a small handful of all-class sidearms available.
=Pistols=
It is worth noting that all pistols that should lock back on their last shot instead repeat the standard firing animation with the slide going forward, with the slide then magically locking back, though the speed of the animations makes it hard to notice without paying attention. All pistol hammers (with the exception of the Steyr M1912 and M1911 Extended) also never move, staying in the cocked position at all times.
==Beretta M1915==
The Beretta M1915 is available as one of the Support class's sidearms as the "Modello 1915." Able to kill in 4 shots at short distances, it offers a decent sized magazine at 8 rounds plus one chambered and a fast rate of fire for the pistol class, with a fire rate of 450 RPM. 
==Borchardt C-93==
The Borchardt C-93 is an available pistol that can be utilized by all classes once unlocked by getting to Rank 10 with the Support Class. It inflicts similar damage to some of the faster firing pistols at 4 shots within close range but is hampered by a somewhat average rate of fire at 360 RPM. It does however possess one of the best hip fire ratings of all the pistols. The carbine version is available in the In the Name of the Tsar DLC for the Tanker/Pilot class.
===C-93 with shoulder stock===
A "Carbine" version of the C-93 with a suppressor and shoulder stock is available in the In the Name of the Tsar DLC as a sidearm for the Pilot and Tanker class. It is the first multiplayer weapon that uses the Maxim Silencer that was previously only present on certain weapons in the single-player mode. 
==Colt 1903 Hammerless==
A Colt 1903 Hammerless is available for the Assault class. It is the fastest-firing pistol in the Assault Class at 450 RPM but is also relatively weak, killing in about 4 shots at close range. 
==Colt M1911/A1==
The "M1911" in the game is a hybrid with features of both the M1911 and M1911A1, the latter being anachronistic since the M1911A1 was not standardized until 1926. It has a long M1911-style trigger and hammer spur and a short grip safety spur, but an A1-style frame cutout behind the trigger, no diamond markings on the grip, and a curved mainspring housing. The M1911 is the default starting pistol and is able to kill a target within 3 shots at close range: The rate of fire is moderate, enforced by a 300 RPM firecap, and reload time is also moderate, but spread and recoil are more severe than other pistols. An all-class suppressed variant was added to the CTE for testing in June 2018.
Following the announcement of Battlefield V, multiple pre-order bonus weapon variants were added to the game, awarded to those who pre-ordered BFV. These weapon variants all represent interwar developments of the base weapons. The pre-order bonus variant for the M1911, despite being named M1911A1, is merely the base game hybrid M1911 with a reskin.
===Colt M1911/A1 "Extended"===
The "M1911 Extended" is a pistol-carbine variant of the Colt M1911, used by Tankers and Pilots. It is semi-automatic, has a capacity of 14+1 rounds, and is fitted with a wire-frame stock and Thompson-style foregrip (the same foregrip featured on Trench-variant weapons in the game). Initially, the weapon incorrectly functioned in double-action (the hammer even cycled), the slide didn't lock open on empty, and the sights didn't move with the slide; these issues were later fixed in a patch.
==FN M1903==
The FN M1903 is available by default alongside the M1911 and P08. Called the "Mle. 1903" in-game, it offers a balance between the two other default sidearms by being faster than the M1911 and P08 but offering less damage as a result. It has a fire rate of 360 RPM.
As a trivial note, the French "Mle." name is interesting considering that neither the French nor the Belgians used this pistol, the Ottoman and Russian Empires did.
===Mle. 1903 Extended=== 
The They Shall Not Pass DLC adds the "Mle. 1903 Extended" for the Pilot and Tanker classes, with a stock and 10-round magazine.
==Frommer Stop==
The Frommer Stop is available for the Scout Class. It is yet again another fast-firing pistol at 450 RPM but is offset with low damage at 4 shots at close range. Unlike other 4-shot, high ROF pistols it only holds 7 rounds plus one chambered instead of the usual 8 plus 1. 
===Frommer Stop Machine Pistol===
The fully automatic lengthened-barreled variant of the Frommer Stop is available to the Assualt, Pilot, and Tanker classes as the "Frommer Stop Auto". To better make use of its fully automatic capability, it is fitted with an extended magazine, which has a correct capacity of 15 rounds.
==Kolibri Pistol==
The tiny Kolibri 2.7mm Pistol is the weakest and smallest pistol in the game, unlocked by getting to Rank 10 with the Scout Class. The weapon seems to have been included primarily as a joke similar to the old ability to kill someone by hitting them in the head with a stun grenade; its damage output at point-blank range is only 5 per shot, and it can only reach levels comparable to other pistols when aiming for the head. Even then, it only deals 25 damage - respectable, but not for a point-blank headshot. It has an incorrect magazine capacity of 7+1 rounds instead of 6+1: this is probably due to misinterpreting a Forgotten Weapons video about a Kolibri up for auction that came with seven rounds of ammunition.
There is a humorous third-person "Easter Egg" reload that occasionally happens with the Kolibri: rather than reloading it, the player character will be shown patting the ground as if they have dropped it and can't find it.
==Lancaster Howdah Pistol==
A Lancaster 4-barreled Howdah Pistol is available to the Assault Class. It is a 2 shot kill at close range, but damage drops off sharply at longer distances; in comparison to the Gasser, it offers a faster rate of fire (257 RPM compared to the 180 RPM of the Gasser) and a much faster reload speed as the soldier character inserts two rounds at a time when reloading. 
A unique variant, the "Howdah Sweeper" is also available either in a few of the single-player missions and as an exclusive to DICE employees. As the name implies, it fires some type of shotgun shell and has a circular cross hair due to the pellet spread. This variant is also accessible to all players in the Community Test Environment.
For 100% completion of the campaign "The Runner", the player will be awarded "Frontiersman", a skin for the Howdah Pistol that is usable in Multiplayer.
==Luger P08==
The Luger P08 pistol appears as a sidearm. A heavily engraved Luger P08 appears in the Red Baron Pack, which is included in the Early Enlister Deluxe Edition. It is a 4 shot kill at close range with a moderately fast rate of fire and good hip-fire accuracy. It holds 8 rounds plus one chambered. 
[[File:BF1-Early-Enlister.jpg|thumb|none|600px|Note that the second "Behemoth" is the HMS Iron Duke or a ship of the same class, while the third is the WW1-era Russian / Soviet "rail cruiser" Zaamurets, later known as Polipanovtsi, BP-4, Lenin, Orlik and Train No. 105. This train served on both sides during the Russian Civil War and undertook a remarkable journey across the world, ultimately ending up in the hands of the Japanese military after being seized from Chinese forces in Manchuria.]]
===Luger Carbine/Luger LP08 "Artillery" Hybrid===
A hybrid of the rare Luger Carbine and the Luger LP08 "Artillery" appears as the "P08 Artillerie". It is generally modeled after the Luger Carbine, but it also lacks a grip safety and chambered for 9x19mm Parabellum, which are features of the P08. It used a Trommelmagazin 08 snail drum magazine; although they were usually made under 9x19, some rare/experimental under 7.65x21mm apparently also existed in reality. It is an available weapon for the Tanker and Pilot classes. Despite the increased barrel length it only inflicts marginally more damage at range than the standard Luger P08.
An actual LP08 "Artillery" appears in some promotional art.
==Mars Automatic Pistol==
The Mars Automatic Pistol is available for the Scout class. It has a 10-round magazine, and the files say it is chambered for 8.5mm Mars. It has high stopping power, however, the Gasser Revolver is the most powerful in terms of raw damage. The Mars sports decent hip-fire accuracy but has high recoil and a below-average rate of fire. 
==Mauser C96==
A Mauser C96 is available as one of the Medic class's sidearms. It is relatively weak at a 4 shot kill at close range but can be fired relatively quickly.
On a non-empty reload, the bolt incorrectly slides back without any action from the player character (it should be noted that the C96 does not have a manual bolt hold-open, and the magazine follower functions as the bolt hold-open, meaning that the bolt should only ever lock back when the magazine is empty). The bolt is also manually cocked even when a clip is used; due to the aforementioned use of the magazine follower alone to lock the bolt open, once a stripper clip is removed, the bolt on an actual C96 drops immediately (since the stripper clip is the only thing holding the bolt back at that point).
A suppressed variant called the "C96 Silencer" can be found in the single-player campaigns "Friends in High Places" and "The Runner".
A version of the weapon available only to the DICE developers is the "Export" variant, chambered in 9x25mm Mauser Export, which deals more damage, but has noticeably more significant recoil.
For 100% completion of the campaign "Through Mud and Blood", the player will be awarded "His Lordship", a skin for the Mauser C96 that is usable in Multiplayer. 
===C96 Carbine===
A carbine Mauser C96 with a slab-sided receiver and an aperture rear sight appears as the default primary weapon for the Pilot and Tanker classes. Oddly, the weapon has a 20-round fixed magazine; while these did exist, they weren't ever recorded as being put into carbines. Despite being a Carbine it inflicts identical damage to the regular C96 at 4 shots and only has a slightly higher muzzle velocity. 
===M1917 Trench Carbine===
The M1917 Trench Carbine, a rare prototype 9mm Mauser C96 carbine variant (less than 100 guns produced) with a 9.5-inch barrel and a massive 40-round detachable magazine produced by Mauser near the end of the war, appears in the Turning Tides DLC for the Assault class as a primary weapon. The real gun was supposed to compete with the Trommelmagazin-equipped Luger as a trench raiding weapon, but was never adopted on cost grounds. A scoped version referred to as "M1917 Patrol Carbine" was added with the May 2018 update.
In the files, the weapon's projectile was originally incorrectly named "Mauser763x25mm_Carbine", despite the real gun only being made in 9x19mm Parabellum, however, this was corrected in a patch to "9x19mm_Semi". Considering this name cannot actually be seen in-game, this is some impressive dedication to getting things right.
==Mauser M1914==
The 1914 Mauser Pocket Pistol is available as one of the Medic class's sidearms as the "Taschenpistole M1914" (which is German for "pocket pistol"). It is a faster firing pistol at 450 RPM, but like other pistols in the same role is relatively weak, killing in 4 shots. 
==Steyr M1912==
The Steyr M1912 appears as a Support-exclusive sidearm, called the "Repetierpistole M1912". When performing a non-empty reload, the player character correctly opens the action and presses a button that dumps all remaining rounds from the gun, then loads it with a stripper clip. When empty, the gun simply locks open like most pistols and is then loaded with the clip, making an empty reload much faster. Considering Support has access to infinite ammo, it's likely a good idea to empty the pistol whenever using it. It should also be noted that the gun actually ejects the correct amount of remaining rounds, ranging from one to seven. It is relatively weak, killing in 4 shots with a moderately fast rate of fire at 360 RPM.
===Steyr Anschlagpistole M.12===
The machine pistol version of the Steyr M.12, complete with a 16-round extended magazine and buttstock, appears as an Assault-exclusive primary in the Turning Tides DLC, called the "Maschinenpistole M1912/P.16". Although the "P16" suffix (supposedly standing for "Patronen 16" or "16 bullets") is common in online sources when referring to the machine pistol variant, it never appears in contemporary documentation. The term "Maschinenpistole" was also not used by the Austro-Hungarians during the First World War; "Anschlagpistole" ("Assault pistol") was the term adopted for this weapon.
The in-game model is not actually based on the real machine pistol, but rather an early prototype variant of the M.12 pistol which had an adjustable tangent rear sight instead of fixed iron sights. The fire selector that allows the weapon to fire fully-automatic is not present on the game model, meaning that the gun is essentially just a standard M.12 pistol with an extended magazine. There is no animation for switching fire modes. The buttstock is also incorrectly depicted as a standard M.12 holster stock with a flat butt, rather than the special proprietary stocks that were coupled with the machine pistols, which bore enlarged butt pads to secure the stock against the user's shoulder.
Unlike the sidearm, the machine pistol is reloaded with both stripper clips and individual rounds; a reload from empty uses two stripper clips, while non-empty reloads without a multiple of eight load some individual rounds, like other clip-loaded guns in BF1. Although all of its animations were redone from scratch, it maintains the same details as the sidearm version (and was done by the same animator), such as releasing the safety every time the weapon is drawn, and correctly locking the slide open using the safety when reloading before the gun is empty. Also worth noting is that the player character uses their dominant thumb to press the slide release on empty reloads, but uses their offhand thumb to disengage the safety on non-empty reloads, which helps make the use of the slide catch vs the safety more obvious to the average player.
=Revolvers=
==Bodeo M1889==
The Bodeo M1889 is available for the Scout class at rank 2. A reasonably powerful 2 shot kill at close range however damage drops off sharply at longer distances to the point it will require all 6 rounds to kill a soldier at max range. It is painfully slow to reload as it reloads via a reloading gate, removing spent cartridges one at a time and inserting new ones. Although it is also reloaded in what seems to be a rather unsafe manner (pulling the trigger to rotate the cylinder after each round is inserted), this is how the Bodeo is supposed to function; with the loading gate open, the hammer is disconnected from the trigger, allowing this faster method of reloading compared to other gate-loaded revolvers.
A close inspection of the animations shows that the cylinder never rotates when firing.
==Colt Single Action Army==
Following the completion of a series of extremely elaborate Easter Eggs (spanning the entire support cycle of the game, including all 4 DLC packs), players were rewarded with a 7.5" "Cavalry"-barreled Colt Single Action Army, dubbed the "Peacekeeper" in-game. It has ivory grips, a deep blued finish, and engravings with a silver inlay, most prominently a skull carved into the left recoil shield. Its damage is very high, more comparable to the Obrez than other revolvers. The player character fans the hammer when hip firing, allowing for automatic-in-gameplay firing like the Gasser.
Notably, the Peacekeeper's reload animations show the player character first turning the cylinder clockwise, past the unfired rounds still in the cylinder, before starting the eject-reload-rotate clockwise routine. This is in contrast to the other gate-loaded revolvers in BF1 (and many other games), which immediately start the reload routine at the position the cylinder was in. This fixes the logical error present within the latter animation: because the cylinder rotates clockwise after firing, all the fired rounds are rotated clockwise, first into the ejection position, then past it. Therefore, performing the eject-reload-rotate clockwise routine immediately will actually miss most of the fired rounds, and eject a lot of unfired rounds.
The Peacekeeper has a very flashy set of weapon animations, with the player character performing various elaborate tricks when drawing, reloading, or even just running with the gun out; this, coupled with the in-game description ("According to some, this is the greatest handgun ever made."), and the dog tag unlocked alongside it (bearing the message "Tu Es Satis Bonus", Latin for "You're Pretty Good") solidifies the weapon as a reference to Metal Gear Solid 3. Each of the six possible reload animations are individual animations with different weapon tricks, and account for the amount of ammunition remaining in the revolver during the indexing process (reloading after firing just one round doesn't involve the indexing and is just a simple eject-and-reload). The empty reload has the user ejecting all the fired rounds first before reloading all the rounds in one go instead of the typical eject-load repeat cycle.
==Gasser M1870==
The Austrian Gasser M1870 revolver is available and is exclusive to the Assault Class. It is likely the 11.25x36mmR model, as the description states it was favored by Austrian Stormtroopers. It fires in single action animation-wise but allows for automatic firing when not aiming down sights (i.e. holding down the fire key will repeatedly fire it), with the player character's thumb very quickly cocking the hammer back after every shot. More interestingly, the third-person animation shows the player character's left hand coming up to cock the hammer after every shot, an animation unique to this weapon. It is a pain to reload due to its loading gate system, and is, unlike the other revolvers, a very reliable two-hit kill weapon at medium distances.
==Nagant M1895==
The Nagant M1895 is available in the In the Name of the Tsar DLC as a sidearm for all infantry classes. It is used exclusively in single-action, which could either be a result of the Nagant's infamously heavy double-action trigger pull, or it could be to imply that the revolver in-game is actually a "Private's Model" Nagant, which looks identical to the standard version, and is in fact single-action only. When reloading with ammo remaining, it loads like any other gate-loaded revolver; however, if the weapon is empty the 7-round cylinder is removed entirely and replaced with another one.
==Smith & Wesson No.3 Russian Model==
The Smith & Wesson No.3 Russian Model is available, simply called "No.3 Revolver". It is based on the commercial version (note the missing trigger guard spur of the military model) and according to the in-game stats is chambered in .44 American (which is not wrong, since some of the commercial revolvers were chambered in this caliber). It can be used by all classes but must be unlocked by getting Rank 10 with Assault. Like other Revolvers, it is somewhat powerful at close range killing about 2 shots but damage drops off sharply at long range. It is one of the only three top-break revolvers in the base game offering a much faster reload in comparison to other revolvers. It is also used by the "Trench Raider" elite class, which was added in the They Shall Not Pass DLC.
==Webley RIC==
A Webley RIC revolver is available as one of the Support class's sidearms, under the name "Bull Dog Revolver" (a type of revolver the RIC is a member of). Like other revolvers, it is a 2 shot weapon at close range and is the fastest firing of the Revolver class at 257 RPM (in comparison to the Auto Revolver which has 225 RPM) but damage drops off sharply at longer ranges to counter its fast rate of fire. The weapon reloads via a loading gate, ejecting and inserting new rounds one at a time. The in-game weapon's caliber is specified as .442 Webley in game files.
==Webley Mk. VI==
The Webley Mk VI revolver appears in the Apocalypse DLC under the generic name of "Revolver Mk VI".
==Webley-Fosbery Auto Revolver==
The Webley-Fosbery Automatic Revolver is shown being used by several tank crewmen during the campaign mission "Through Mud and Blood". In multiplayer, it is one of the Medic class's sidearms, offering a high damage 2-shot kill at close range, with damage dropping off sharply at longer ranges, and a faster reload in comparison to other revolvers. It is called the "Auto Revolver" in multiplayer - which is more or less correct, but not terribly specific; an auto-revolver is a type of weapon (albeit with very few of the sort existing), not an individual one. Like the S&W No.3 Revolver, it reloads via a top break system and is thus able to replace all of its rounds at once.
The Auto Revolver is named "Automatic Revolver .38" in single-player but still holds 6 rounds instead of the 8 rounds capacity of the .38 ACP variant. Despite this, in the final cutscene of Through Mud and Blood Townsend fires eight shots from his Auto Revolver without reloading, the correct full capacity of the .38 variant.
For 100% completion of the campaign "Friends in High Places", the player will be awarded "Straight Flush", a skin for the Auto Revolver that is usable in Multiplayer. 
=Submachine Guns=
Worth noting is that none of these weapons would have been called submachine guns in English at the time, because the term originated in 1921 as a description for the Thompson Submachine Gun; terms like "machine carbine" or "machine pistol" were used in Europe for such weapons right up to the Second World War. For other languages however, such as German, the corresponding term Maschinenpistole was invented during WWI and used to the modern day.
The SMG category also includes the Steyr M.12/P.16 machine pistol, the Ribeyrolles 1918 (an automatic carbine using a proto-intermediate cartridge, designed as a light machine gun of sorts), the Chauchat-Ribeyrolles 1918 (a firing port weapon using rifle rounds which some sources say that the French did call a "submachine gun" by naming it a pistolet-mitrailleur), and weirdly, the M1917 Trench Carbine, despite it not even being automatic.
Like the machine guns, some of the large-capacity submachine guns (namely the Hellriegel and the Schwarzlose SMG) can overheat after being fired for too long.
==Beretta M1918==
The Beretta M1918 is available for the Assault class at rank 2. In-game, it is incorrectly depicted as a fully automatic submachine gun, even though the real Beretta M1918 was a semi-automatic carbine. Presumably due to the continued existence of Beretta's name trademark, it is called the "Automatico M1918" in Battlefield 1.
The M1918 has the fastest ROF of the Assault SMGs at 900 RPM but is offset with a magazine size of 25 rounds and very poor damage drop-off. Three variants exist for the weapon with pre-allocated attachments, "Factory", "Trench" and "Storm". An Optical variant that uniquely had the lens sight mounted diagonally was initially planned (and can be seen in the official gameplay trailer), but was later scrapped for unknown reasons.
The in-game model has a number of inaccuracies and oddities. The iron sights are mounted on the wrong side of the receiver (left instead of right). The default trigger position, visible in the weapon inspection screen, shows it to be retracted backwards, as if it is always pulled back. The cocking slot is depicted as being fully straight instead of having a 45° locking cam that was present in the real weapon, and the cocking handle is made of solid steel instead of wood. Its magazine release is incorrectly modeled. The bolt is not animated at all; in the Alpha and Beta stages, the bolt correctly reciprocated upon firing, but the release version of the bolt stays completely static, likely due to an animation error that was never fixed.
==Bergmann MP18/I==
The Bergmann MP18 is the first submachine gun available for the Assault class. It is the slowest firing SMG at 500 RPM but offers good accuracy over short to medium distances even from the hip. Three variants are available "Trench", "Optical" and "Experimental". The "Experimental" variant locks the weapon to a three-round burst and gives substantially greater long-range accuracy, and after the 2018 Easter update, it now feeds from a 30-round stick magazine to prevent having a leftover two rounds in a three-round burst fire weapon (while the Experimental variant that appears in the single-player level "The Runner" still visually loads from the snail-drum mag). This magazine appears to have been modeled after a rare Swiss-made 16-round Luger magazine from the 1910s (). The "Factory" variant is available in the single-player.

==Schwarzlose submachine gun==
The obscure Schwarzlose submachine gun is available in the In the Name of the Tsar DLC for the Assault class, with Factory and Optical as its two variants. The real weapon, designed by German firearm designer Andreas Wilhelm Schwarzlose, famous for his Schwarzlose Machine Gun, is based on the MG 08 action, scaled down and rechambered for 9x19mm Parabellum. The weapon's feed mechanism was patented in 1902, and a presumed final design was patented in 1920. It was possible that some work-in-progress model was created during the WWI era. The single surviving gun is part of the collection of the weapon design department of the Tula State University in Russia. The first image below is from the Russian army's collection and shows a slight variation of the Tula weapon's stock with an oil bottle holder, indicating either the Tula gun is a different prototype or the same weapon with a new stock.
The weapon uses a strange multi-column en-bloc clip which functions rather like the "squirrel cage" 50-round magazine of the Fiat-Revelli M1914 machine gun, but without the spring-operated feed columns. The clip is inserted into the left side of the feeding box and has 10 columns of 8 rounds, each column essentially a stripper clip fixed to a backplate. These are indexed upwards by a rack mechanism within the gun rather than a spring follower, the clip being pulled across each time a column is emptied and ejected from the right side of the feeder box when the last round is fired. To balance out this ridiculously large capacity, the in-game gun will overheat after firing around 40 rounds sequentially.
At the time of the game's development, information on the weapon is practically nonexistent on the English internet (for a long time even the weapon's real name is completely unknown, making "Maxim submachine gun" its common name). Details of the gun on the English internet appeared after BF1's release, when a Russian-only print made in 2016 by the Tula State Arms Museum was brought up in the English internet, which finally identified the model. Due to the limited info, the in-game depiction is partially based on speculation on DICE's part: the weapon is named in-game as the "SMG 08/18", based on the Forgotten Weapons article which relates its design to the air-cooled MG 08 variant, the MG 08/18 (which was added to the game 2 DLCs later in the Apocalypse DLC). At release, it had a rate of fire of 450 RPM, but was later buffed to 770 RPM, with DICE providing the reasoning that its smaller caliber and scaled down MG 08 action implies a higher ROF than the original machine gun.
==Standschütze Hellriegel 1915==
The Standschütze Hellriegel 1915 heavy submachine gun is the Assault class's Level 10 unlock, called the "Hellriegel 1915." It is another incredibly obscure prototype, more so than the Schwarzlose submachine gun since not a single example of the weapon is known to have survived the war and there are only three photographs that show it ever existed at all, all of the weapon's right-hand side. Information about the weapon's operating method, ammunition capacity and even which 9mm round it fired is all conjecture from firearms historians based on its dimensions.
The detachable drum magazine depicted on both variants in-game is fictional; the real weapon was known to feed either from a straight box magazine estimated to have a capacity of around 20 rounds, or from a drum magazine with an estimated capacity of around 160 rounds that is noticeably larger than the one in-game. This would be rested on the ground like a belt box using a weighted base, feeding cartridges through a flexible chute that led to early ideas that the weapon was belt-fed. To balance out the high capacity, the Hellriegel overheats at around 40 consecutive shots.
Three variants are available in the game: in singleplayer there is the "Factory" variant that holds 59+1 rounds in a drum magazine and is used by enemies in the chapter "Avanti Savoia!" and a "Storm" variant with a special sight which only appears in a crate in the level "Through Mud and Blood." Multiplayer used to only have the "Factory" variant (which is actually the Storm variant), but now also has a "Defensive" variant introduced to the game in March 2017, which holds 119+1 rounds and is equipped with a bipod and a magnifying sight, and for balance purposes rather than due to any kind of logic, has much higher recoil than the standard version. 
An interesting detail is that the weapon produces water slushing sounds when the player is running with the weapon, likely coming from its water jacket. 
==M1919 Thompson (Hybrid Model)==
An M1919 Thompson prototype of the Thompson SMG was added with the May 2018 weapon update, named the "Annihilator". It comes as a "Trench" variant, using a 20-round magazine. Rather obviously given the name, it is anachronistic for the WWI setting (ignore the Russian Civil War setting for a moment): while there was a 1917 Thompson prototype, this weapon, the "Persuader," was belt-fed.
The in-game weapon, while named after the earliest "Annihilator" prototypes, is physically closest to some of the later prototypes (each M1919 Thompson is slightly different), mixed with an apocryphal perforated barrel shroud. The in-game weapon lacks the adaptor required to use the 20-round magazine on the "Annihilator I", and also features a round charging handle located at the center of the receiver top (the earliest prototypes had strangely shaped actuator handles that are offset to the right side), meaning that it is physically closest to later prototypes.
The Suomi KP/-31-style barrel shroud is likely inspired by this photoshopped image made from a Suomi and an M1A1 Thompson. A Thompson with a perforated barrel shroud however does exist as a diagram in a late 1919 patent (), meaning that the image has a modicum of truth to it.
===M1919 Thompson===
An additional variant is available for pre-ordering Battlefield V, featuring a more true-to-life finned barrel instead of a barrel shroud, called "M1919 SMG".
==Villar Perosa M1915 (Fake)==
A fictional version of the Villar Perosa M1915 is available. It is found in the War Story "Avanti Savoia", and is the weapon of the Sentry Elite Class pickup on the Italian maps (Monte Grappa and Empire's Edge), which was later added to other maps. It is based on the Bapty & Co. mock up made for the 1987 film The Sicilian, on twin Beretta Model 38A with a Bren front grip, and an MG42 grip and trigger group. It has a smaller magazine than the MG08/15 at 50 rounds (both guns loaded), but its blazing rate of fire of 1800 rounds per minute makes it a shredder at close range.

=Shotguns=
==Browning Auto-5==
The Browning Auto-5 is one of the available shotguns for the Assault class. In-game it is known as the "12g Automatic", although a kill feed in the "Gameplay Series" dev diary showed that it was more properly named "Automatic 5" at one point. Like the Sjögren Inertia (and unlike the Model 10A and the Trench Gun), the player character loads an extra round in the chamber; this was most likely done for balancing purposes.
Three variants exist which are "Backbored", "Hunter", and "Extended". The "Extended" model increases the magazine capacity from 4+1 rounds to 6+1, making it the highest capacity shotgun in the game. A factory model with an extended magazine did exist, but the real model holds a 8 rounds, not 6; the in-game Extended model's magazine length is an intermediate between the real 4 round and 8 round magazines. It is modeled with the older style of straight-cut stock, without the “C”-like grip. 
==Remington Model 1900==
The Remington Model 1900 is available in the In the Name of the Tsar DLC for the Assault class. It's correctly named "Model 1900" and comes in two variants - "Factory" and "Slug". By switching fire modes, it's possible to discharge both barrels at nearly the same time. There is in fact a slight delay between shots in "both barrels" mode; in-game mechanic terms it's a two-round burst at an extremely high rate of fire. This simultaneously represents the offset triggers, and also serves as a balance mechanic, to prevent this mode from simply dealing twice the damage with no downside; integrating authenticity-based features into game balance is something the Battlefield series tries very hard to do. This feature is also present on the double-barreled shotgun in Battlefield Hardline.
===Sawn-Off Remington Model 1900===
The Tank Hunter Elite Class is armed with a Sawn-Off Remington Model 1900 as his sidearm, though unlike the properly-named full-size version that appears as DLC, this base-game weapon is simply named "Sawed Off Shotgun". The same shotgun can be unlocked as a primary weapon for the Pilot and Tanker classes by reaching Rank 10 with the Tanker class. This version has the "Shotgun Rib" style iron sights on by default, and as Pilot/Tanker weapons lack proper customization, it cannot be removed. Having been added to the game earlier, it lacks some improvements/features the full-size version has, such as reloading just one shell when only one has been fired, the "both barrels" fire mode, and a correct name. As of the In the Name of the Tsar update, this version now has the double-barrel fire mode as well. The later-added Infiltrator Elite Class uses this weapon as his secondary as well.
==Remington Model 10A==
The Remington Model 10A is the first shotgun unlocked for the Assault class and is referred as the "Model 10-A". It differs from the Winchester Model 1897 for having a longer barrel of 23 inches, rather than 20 inches on the Model '97. It has a correct 6-round tube capacity in the game and unlike the M1897 cannot be slam fired. Like the M1897, it cannot hold an extra round in the chamber. Instead of starting with a chamberloading procedure, the empty reload instead involves filling up the tube magazine then pumping once to chamber the weapon (same on the M1897). Three variants are available in-game, "Factory", "Slug" (Formerly called "Heavy" in the Beta) and "Hunter". 
==Sjögren Shotgun==
The Sjögren semi-automatic Shotgun was confirmed by the developers to be in the They Shall Not Pass DLC and was seen in a teaser image. It is referred to as the "Sjögren Inertial" in-game, referring to the Sjögren's inertial action, even though the name of the real weapon is actually Sjögren Inertia. It has a capacity of 4+1 rounds in-game. A slug variant was added in May 2018. As with the pistols and the Luger rifle, it does not lock back on the last shot, instead repeating the standard firing animation with the bolt going forward, with the bolt then magically locking back. 
==Winchester Model 1897 "Trench Gun"==
The Winchester Model 1897 Trench Gun is one of the available shotguns for the Assault class under the name "M97 Trench Gun." It correctly holds 5 rounds in the tube magazine and is also capable of being "slam-fired" in-game, just like in real life. However, like the Remington Model 10A (and unlike the Browning Auto-5 and the Sjögren Inertia, as well as shotguns in previous Battlefield games), the player is unable to load a round in the chamber; this was likely done for balancing purposes. Four variants exist in Multiplayer, these being "Hunter", "Backbored", "Sweeper" and "Hellfighter". The "Hellfighter" is only a cosmetic pre-order bonus apart of the Early Enlister and Deluxe edition copies of the game; statistically, it is identical to the M97 Hunter variant.
=Self-Loading/Revolving Rifles=
Rifles are primarily split into two classes: Self-Loading Rifles used by Medics, and Rifles used by Scouts.
==Cei-Rigotti==
The Cei-Rigotti, an obscure Italian select-fire rifle with a production run of around 260, is the first rifle available for the Medic class. It comes in three variants: "Factory", "Trench", and "Optical", which are all converted into full auto. Though rates of fire of up to 900 RPM are claimed for the real-life weapon, the in-game gun runs at a much slower 299 RPM, in line with the low-end estimates for the real gun. The rifle itself is described as 6.5x52mm but is modeled with a 10-round magazine of 7.65x53mm version. Real documents show a 6.5mm version with a 6-round magazine, superficially reminiscent of the Carcano M91. The player character chambers the Cei-Rigotti by pushing the bolt handle home - the correct procedure is to use the "winter style" trigger extension that functions as a bolt release, similar to the Farquhar-Hill. This functionality wasn't widely known until late 2022, well after Battlefield 1's release.
The text CEI-RIGOTTI M1885 is engraved on the side of the weapon's receiver, which is odd - the real-life Cei-Rigotti has no recorded development date and is only known to have been first shown sometime around 1895.
For 100% completion of the campaign "Avanti Savoia" the player will be awarded "Fiamme Verdi", a skin for the Cei-Rigotti that is usable in Multiplayer.
==Chauchat-Ribeyrolles 1918==
The Chauchat-Ribeyrolles 1918 is available in the Apocalypse DLC for the Assault class as the "RSC SMG", and was first known as the "CSRG SMG" in early CTE releases. Both names allude to the origin of the weapon: Chauchat, Sutter, Ribeyrolles, and the Gladiator plant. The SMG name and classification seemingly contradicts with its rifle caliber, but this is not strictly an error on the part of the designers, since the weapon was referred to at the time as a pistolet-mitrailleur which is the modern French term for a submachine gun. It holds 8+1 rounds in the magazine and comes in the "Factory" and "Optical" variants.
==Farquhar-Hill Rifle==
The Farquhar-Hill Rifle appears in the Turning Tides DLC for the medic class. It is exclusively used with 19-round drum magazines and is available in two variants: "Factory" and "Optical".
[[File:BF1 Farquhar-Hill (1).jpg|thumb|none|600px|Inserting a drum magazine into the Optical Farquhar-Hill, careful to heed the advice of Gun Jesus.]]
==Fedorov Avtomat M1919==
The Fedorov Avtomat M1919 is available in the In the Name of the Tsar DLC for the Medic class. It has a faster rate of fire than the "M1907 SL Trench," and a 25+1 round magazine, but is limited to medium range due to its recoil. It comes in two variants - "Trench" and "Optical".
It is shown being reloaded by swapping out the detachable magazine, which is physically sort-of-possible but historically not completely correct. While this was how the weapon was originally envisioned as being used, production costs and problems with overheated on full-auto fire meant that in real life each Fedorov Avtomat was only issued with a three magazines (four in WWI), usually reloaded with 5-round Arisaka stripper clips inserted into the breech as if the magazine was fixed. Even if the gunner somehow acquired another magazines, they were fitted to individual guns and so there would be no guarantee it would actually be possible to use it. I.e. magazine should be replaced only with empty reload.
The Avtomat in the game is modeled after the later M1919 variant (with a modernized magazine from the later M1923). The real 6.5mmSR M1916 variant doesn't have the barrel shroud and vertical grip. Moreover, in real life, the 7.62mmR M1913/1916 version with a 15-round Madsen-pattern magazine was much more common during WWI (only about 8 M1916s were delivered to the front, compared to the 45 M1913 and M1913/1916 guns).
===Fedorov-Degtyaryov Maxim Type===
The water-cooled version of Fedorov-Degtyaryov (alternately spelled as Fedorov-Degtyarov and Fedorov-Degtyarev based on different Anglicization methods, the latter of which is its in-game name and technically the only one with consistent anglicization) was a bonus weapon variant available to players who pre-order Battlefield V. The Fedorov-Degtyarev is a 1922 LMG development of the Fedorov Avtomat between Vladimir Fyodorov (anglicized as Fedorov, designer of the Fedorov Avtomat) and his apprentice Vasily Degtyaryov (who would later design the famous DP-28 light machine gun).
==General Liu Rifle==
The General Liu Rifle is available in the In the Name of the Tsar DLC for the Medic class. It has a 6-round magazine and at release operated exclusively in semi-automatic mode.
The real General Liu rifle can switch from semi-automatic mode to straight-pull bolt-action mode by rotating a cylinder located on the muzzle. This alternate fire mode saw testing in pre-release Community Test Environment servers, but was not included at the release of the DLC due to either lack of time to finish it (there was no fire mode switching animation, though the straight-pull animation was already done) or problems with balance (as the bolt-action mode is a straight nerf, changing nothing about the weapon's damage or recoil properties and only slowing down the rate of fire). It returned again for the April 2018 round of CTE testing with a new fire mode switch animation in the works, which was completed by June 2018 CTE and added to the game in the same month. The new bolt-action mode gives the weapon a damage boost, making its damage model almost identical to the Gewehr 98.
Two variants are available: Factory and Storm. Reloading with 1 round remaining in the magazine will have the player character eject that round and load in a full stripper clip.
==Howell Automatic Rifle==
The Howell Automatic Rifle, a semi-automatic conversion of the SMLE, is available in the Apocalypse DLC, and comes in both Factory and Sniper variants. It was originally named "BSA Howell" in the CTE, which likely stood for the Birmingham Small Arms Company, which manufactured the conversion according to some sources. Most likely this was changed after it was realised that while the original BSA folded in 1973, the Spanish airgun manufacturer Gamo Outdoor still owns the trademark. Uniquely, the Factory variant is the only self-loading rifle in the entire game capable of using anti-aircraft sights.
==Luger rifle==
The prototype Luger toggle-action self-loading rifle is available for the Medic at rank 10, and is referred to as "Selbstlader 1906" (German for "Self-loader 1906"). The magazine contains 5 rounds and it has almost the same characteristics as the Mauser Selbstlader M1916 rifle. It was only available in the "Factory" variant prior to the Spring Patch on April 28 of 2017, which added a Sniper variant as an unlockable. Like its pistol counterpart, it does not lock back on the last shot, instead repeating the standard firing animation with the toggle assembly going forward, with the toggle assembly then magically locking back.
==Mauser Selbstlader M1916==
The Mauser Selbstlader M1916 appears as a primary weapon for the Medic class. It holds 25+1 rounds in the magazine and comes in the "Factory," "Optical", and "Marksman" variants.
==Mondragón Modelo 1908==
The Mondragón Modelo 1908 is available for the Medic class. It is the only self-loading rifle to not have a "Factory" variant, instead, it has the "Storm," "Optical," and "Sniper." In the E3 2016 Trailer, a German soldier is seen with the Flieger-Selbstlade-Karabiner Modell 15 equipped with a 30-round drum magazine. In the final game, only the default 10-round magazine is available for players, but the 30-round drum can still be seen in the cutscene (from the War Story "Through Mud and Blood") that the E3 trailer showed, and can also be found on weapon racks (which feature a few different German rifles) in the campaign, however, the racks, and rifles on them, are non-interactable props. While the real gun can be switched to bolt-action, the in-game Mondragón operates in semi-automatic mode only.
==Pieper Revolving Carbine==
The Pieper Revolving Carbine is an available primary weapon for the Pilot, Tanker, and Support classes, under the name "Pieper M1893".
thumb|none|450px|Pieper Revolving Rifle - 8mm Pieper
==Remington Model 8==
The Remington Model 8 appears as the "Autoloading 8". It has three variants, ".35 Factory", ".35 Marksman", and ".25 Extended". The two calibers, .35 Remington and .25 Remington respectively, translate to different damage models. It is fitted with a semi-pistol grip stock, typically seen on the licensed FN model (or higher end sporting variants produced by Remington).
The third variant, ".25 Extended", is an anachronistic 15-round detachable magazine variant with a wooden foregrip. These models were first made in the 1930s as conversions of existing Model 8s and Model 81s (an updated version made in the 1930s) by the Peace Officer Equipment Company, and in the 1940s a line of "Special Police" Model 81s was made by Remington themselves after conversations between Remington and POE. Its .25 Remington caliber is not made for the Model 81s, and it is not known that POE did any conversions for existing .25 Remington Model 8s, focusing on converting .30 and .35 Remington Model 8s due to their stronger power.
The weapon can use a bayonet in-game, which, although technically possible due to being mounted to the barrel shroud (which does not reciprocate), looks to be barely more than soldered on; it's unlikely it would withstand the strain of actual use.
An easter-egg exists for the ".25 Extended", where the weapon is reloaded in a similar "tacticool" fashion to the Battlefield 4 AN-94.
==R.S.C. Mle. 1917==
The R.S.C. Mle 1917 semi-automatic Rifle appears in the They Shall Not Pass DLC. It is one of the slowest-firing Medic rifles, but also has the highest damage model of any of the Medic's rifles, being capable of killing in 2 body shots out to a decent range.
==Ribeyrolles 1918==
The Ribeyrolles 1918 Automatic Carbine is available in the They Shall Not Pass DLC. Even though technically a rifle, it is classified with the SMGs in-game (despite that as mentioned in that section, the term "submachine gun" didn't actually exist until 1921). By default, the weapon comes with a bipod, and is the best Assault-class automatic weapon at range, at the cost of having the MP18's low rate of fire mixed with the Beretta M1918's low capacity of 25 rounds. An optical variant was added in May 2018.
==Winchester Model 1907==
The Winchester Model 1907 is a weapon issued for the Medic class, named "M1907 SL" in-game. In the Alpha build of the game, the weapon was modeled with a 10-round magazine with a capacity of 20-rounds but has since changed to the correct 20-round (in reality presented in the 1930s) version in the Beta. It comes in the "Factory," "Trench," and "Sweeper" variants; the latter is a fictional variant converted to full-auto firing at 300 RPM.
=Manually-Operated Rifles=
The Scouts' Rifles category (instead of a Sniper Rifles category) likely reflects how many of the rifles have Infantry variants that lack scopes, making them unsuitable for sniper roles. Rifles are universally bolt-action with one lever-action rifle and a single-shot rifle (and one semi-automatic rifle, and even then it's a conversion for a bolt-action rifle), while Self-Loading Rifles may be semi and/or fully automatic.
In Battlefield 1, one of the Scout class' gadgets allows their rifles to use "K bullets". This is short for SmK, "Spitzgeschoss mit Kern" ("pointed bullet with core") and was a 7.92x57mm armor-piercing rifle round with a tool steel or tungsten carbide core, developed by Germany in response to the first British tanks and first deployed in the Battle of Messines Ridge in early June 1917, by which time the Mark IV tank was in service with more armor than the K bullet was designed to penetrate. In the game, they can be used by rifles chambered in other calibers, and are mainly to allow Scouts to harass vehicles. Switching to them from the primary weapon involves a special animation where the player character ejects a round and loads in a K bullet. They're functionally single-shot, as the player character loads in a single new K bullet after firing one (provided that they have any left). Switching from them back to the primary weapon will have the loaded K bullet ejected, and the player's magazine will have 1 less round loaded compared to before the switch. This does not happen in two cases: The M1903 Experimental (where the Pedersen Device is removed and reattached during the two animations) and the Carcano 1891 Carbine (where its en-bloc clip is removed when switching to the K bullets and a full en-bloc clip of ammo is loaded in when switching back)
==Arisaka Type 38==
The Arisaka Type 38 rifle appears as a Scout-exclusive primary rifle in the Turning Tides DLC. At first, it only had one variant available, the Infantry variant, but the May 2018 update added a scoped "Patrol" variant. Reloading with 1 round remaining in the magazine will have the player character eject that round and load in a full stripper clip of ammo (this mechanic was first introduced in In the Name of the Tsar).
==Carcano 1891 Carbine==
Italian soldiers in the reveal trailer are seen with what appear to be ersatz Carcano 1891 Cavalry Carbines made out of the game's Mauser Gewehr 1898 rifle model. The model, while only witnessed briefly, is very incomplete. The Carcano ultimately does not appear in the release version of the game, but appears with the Turning Tides DLC for the Scout class. Although it has "Carbine" in the name, that title is purely reference to its real-world status as a carbine, not a BF1 weapon variant name; the rifle is actually a Trench variant, like the Winchester 1895 in .30-40 Krag. A scoped variant was added with the May 2018 update.
Learning from the animation messes relating to the en-bloc clip of the Gewehr M.95, switching to the K bullet shows a special animation where the player character removes the clip and inserts a round directly into the chamber. Reloading with 1 round remaining in the magazine will have the player character eject that round and load in a full en-bloc clip (the clip having emptied itself and dropped out when the last round was chambered).
==Lebel Mle. 1886==
The Lebel Mle 1886 Rifle appears in the They Shall Not Pass DLC, having both "Sniper" and "Infantry" variants. The weapon holds 8 rounds - the capacity of the tube magazine, with the 2 extra rounds that could be held in the transporter and the chamber ignored (which is the standard procedure in the French Manual of Arms).
The weapon has a lengthy post-reload animation, showing the player character operating the bolt twice to use the transporter after loading up the tube magazine. In addition, due to using a transporter, the player character does not cover the Lebel's ejection port at the start of a non-empty reload unlike other rifles, and visibly ejects a round. This round is placed back in during the non-empty reload's post-reload animation, and is not represented in gameplay; the ammo count doesn't reduce by 1 when this extra round is ejected, nor does it increase by 1 when it is loaded back in, only the rounds loaded in-between increment the ammo count. These post-reload animations can be skipped by quick switching.
==Lee-Enfield No. 1 Mk. III==
The Lee-Enfield No.1 Mk.III rifle is available for the Scout class and is the standard issue rifle for the British faction in the 'Back to Basics" game mode or games with the "Standard Issue Rifles" server setting. It comes in three variants: "Infantry", "Carbine", and "Marksman".
===Lee-Enfield Carbine===
The short version of the SMLE is equipped with the experimental dot sight. This carbine seems to be a cut-down version of the No. 1 Mk. III.
==M1917 Enfield==
The M1917 Enfield is added in the final Apocalypse DLC. Statistically, it is a straight upgrade to the Springfield M1903, as it shares its damage, velocity, and drag with the Springfield M1903 due to their shared .30-06 cartridge, but has a higher rate of fire and an extra round in the magazine. A suppressed Enfield with a scope was added with the May 2018 update. It uses 5-round stripper clips but has a 6-round magazine, requiring 1 stripper clip plus 1 extra single-round reload to reload from empty.
==Mannlicher M1895==
The Mannlicher M1895 appears as the "Gewehr M.95", a primary weapon for the Scout class. In pre-release versions of the game, the M1895 could be incorrectly reloaded with individual rounds, however, in the final release, the en-bloc clip is ejected when reloading mid-magazine (there are always five unfired rounds modeled in the clip, though).
Being a straight-pull bolt action, it has the properties of the straight-pull bolt attachment seen in previous BF games, where the player can operate the action without having to unscope first (the Carbine, Infantry, and Trench variants of non-straight-pull weapons also have this property, just with a lot more shaking when operating their action). It comes in the "Infantry," "Carbine," and "Marksman" variants, with the Infantry version given to the Austro-Hungarian empire in the "Back to Basics" game mode and games with "Standard Issue Rifles" enabled.
===M.95 Carbine===
A short version of the Mannlicher M1895 is also available, equipped with a magnifying sight. The in-game model is a short version of the full-length rifle variant.
==Martini-Henry==
The Martini-Henry is available for the Scout class in the game. It boasts itself as the highest-damaging sniper rifle but only holds a single round. Additionally, it has the longest "sweet spot" of any sniper rifle; this is the range in which the weapon will be able to score 1-shot kills to an enemy's torso. The Martini-Henry was originally the standard rifle for the Ottoman Empire in the "Back to Basics" custom game mode and games with the "Standard Issue Rifles" server setting, before being changed to the Gewehr 98 (historically, Martini-Henry rifles were used in some quantity by the Ottoman Empire). The weapon only had an Infantry variant until the Spring Patch on April 28, 2017, which added a Sniper variant.
==Mauser Gewehr 1898==
The Mauser Gewehr 1898 is available for the Scout class. In "The Runner" campaign Ottoman soldiers use this rifle instead of accurate 1893 and 1903 Mauser rifles. The Gewehr 98 was delivered to the Ottomans only towards the end of the war, so their appearance in the "Nothing is Written" missions is correct. It comes in the "Infantry", "Marksman", and "Sniper" variants. It is also the standard issue rifle for the German Empire in "Back to Basics" mode and servers with "Standard Issue Rifles" on, and had replaced the Martini-Henry as the standard issue rifle for the Ottoman Empire.
==Mauser Tankgewehr M1918==
The Mauser 1918 T-Gewehr is exclusive to the Tank Hunter battle pickup class in-game and is capable of dealing terrifying amounts of damage to vehicles and infantry alike, at the cost of a 1-shot capacity, a slow reload, and the rather understandable inability to use the weapon without the bipod deployed. The Mark V tank can also be equipped with two T-Gewehrs; this is actually historically correct, as some German "Beute-Tanks" like the Mark IV were re-equipped with this rifle.
==Mosin-Nagant M1891==
The Mosin Nagant M1891 is available in the In the Name of the Tsar DLC for the Scout class. Like other weapons in the "Tsar" DLC, it has differing reloads depending on how much ammo remains (more variation than existing weapons). For example, if only one round remains, the character will let it eject into their hand and then put it in a pocket (rather than keep it in the rifle as current bolt actions do), then load a full five-round stripper clip. If three rounds remain, the character will keep the ejecting round in the gun and simply load two by hand, although not with two looped animations as is standard, but rather will hold both in their hand at once and put them in after each other. It comes in two variants - "Infantry" and "Marksman".
While loading the stripper clip, the player character lifts the top round on the clip upwards before pressing down. This is a trick to prevent the clip from misaligning with the gun while loading.
===Mosin-Nagant "Obrez"===
A sawed-off Mosin-Nagant M1891 "Obrez" is also included in the In The Name Of The Tsar DLC, as an all-class sidearm. The entire stock of the weapon is removed and replaced by an improvised wooden pistol grip, leaving all the internal assemblies exposed. Like its rifle brother, it also has a different reload animation for all possible amounts of remaining ammo, including the ejecting the last round to use a stripper clip technique. In addition, it has two different bolt-pull animations.
===Mosin-Nagant M38 Carbine===
The Mosin Nagant M38 Carbine is a bonus interwar-era weapon variant for pre-ordering Battlefield V. It can equip a bayonet, unlike the real M38 carbine. Needless to say, this weapon is very anachronistic.
==Ross Mk. III ==
The Ross Mk III is included with the Apocalypse DLC. It only appears as a "Marksman" variant, equipped with the M1913 scope, which was actually used on some Ross rifles in reality. The "Infantry" variant was brought in with the May 2018 Update. Being straight-pull in real life, it uses straight-pull bolt action game properties (no need to scope out to operate the bolt) in-game, and reloading with 1 round remaining in the magazine will have the player character eject that round and load in a full clip.
Weapon malfunction is thankfully not simulated in Battlefield 1, meaning that the player won't have to worry about the problems that plague the real Ross rifle.
==Springfield M1903 Mk. 1==
The Springfield M1903 Mk. 1 is one of the available rifles for the scout class. The M1903 is the only bolt action rifle to not feature an "Infantry" variant in-game, only having a "Sniper," "Marksman," and "Experimental" variants, with the latter being fitted with the Pedersen Device. The "Infantry" version of the weapon appears in the single-player campaign intro and is available to the American faction in the "Back to Basics" game mode (added December 16th, 2016) and the "Standard Issue Rifles" server setting.
===Pedersen Device===
The Springfield M1903 Mk. 1 fitted with the Pedersen Device is available in the game as a variant of the regular M1903 (M1903 Experimental). This device makes the weapon function as a semi-automatic rifle firing the experimental .30 Auto-Pistol round, which can be considered a mix between the .32 ACP and the WW2-era .30 Carbine. Production began in 1917 and it was officially adopted as US Automatic Pistol, Caliber .30, Model of 1918. However, the war ended before it saw combat usage; it would have been in use during the 1919 Spring Offensive. 
If the player switches to K Bullets while having this variant active, a unique animation plays when switching, where the soldier removes the Pedersen device and replaces it with the original bolt of the 1903, turning the semi-automatic rifle into its original .30-06 bolt-action form (and vice versa). It's worth noting that when using the original bolt with K-Bullets, the rifle is actually the no attachments setup that is otherwise unavailable in multiplayer, just without the ability to use standard rounds in a five-round magazine.
Due to player demand for the Infantry variant in multiplayer, one round of CTE testing in early 2018 added a new “fire mode” to the M1903 Experimental, which would remove the Pedersen device in the same way as the K Bullets and return the weapon to bolt-action, using normal .30-06 rifle rounds, essentially turning it into the M1903 Infantry. In this mode, the rifle cannot be zeroed. This was added to the game proper in July 2018.
==Vetterli-Vitali M1870/87==
The Swiss-Italian Vetterli-Vitali M1870/87 is available in the In the Name of the Tsar DLC for the Scout class. Due to its 10.35x47mm round and 4 round magazine, it can be defined as an advanced alternative to the Martini-Henry rifle, with similar muzzle velocities. When reloading with 1 round remaining in the magazine, the player character will eject that round and load in a full clip. This mechanic (a simplified version of the Mosin-Nagant's five-different-reload-animations dynamic reload) would reappear on future BF1 DLC rifles.
===Vetterli-Vitali M1870/87 Carbine===
The rare carbine variant of the Vetterli-Vitali M1870/87 is also available with the experimental dot sight.
thumb|none|450px|Vetterli-Vitali M1870/87 Colonial Cavalry Carbine - 10.35x47mm R
==Winchester Model 1895 (Russian Contract)==
The Winchester Model 1895 appears as the "Russian 1895" and a primary weapon for the Scout class in multiplayer. Three variants are available to the Scout class, the "Infantry” and "Sniper" variants chambered in 7.62x54mmR, and the "Trench" variant being a carbine model chambered in .30-40 Krag. If the player spawns in as the Cavalry class, they are given a fourth "Cavalry" variant of the weapon, which is similar to the "Trench" (same caliber) but with reduced hip-fire accuracy and increased muzzle velocity.
An animation error on the Sniper variant makes the hammer return to the down position for a quick moment after scoping out after a shot.
For 100% completion of the campaign "Nothing is Written" the player will be awarded "Desert Dweller", a skin for the Russian 1895 that is usable in Multiplayer. 
=Machine Guns=
For the first time since Battlefield 2, handheld machine guns will overheat if fired for too long in Battlefield 1, although some MGs such as the Madsen or M1918 BAR rather obviously don’t have this issue because of their smaller magazine capacities. 
As is common for the video game category for light machine guns, it contains more than what were actually classified as LMGs. The Parabellum MG 14/17 and Perino M1908 medium machine guns are classified as LMGs (though it's less far-fetched for the MG 14/17, considering that it did get to be used on the ground with a bipod towards the end of the war), but the "Annual Award for Most Egregious Weapon Misclassification" goes to the Browning M1917 heavy machine gun being classified as an LMG in Battlefield 1. 
 
==Bergmann MG 15 n. A.==
The Bergmann MG 15 n. A. is one of the Support class's optional primary weapons. Prior to the introduction of the Parabellum MG 14, it was the class's only belt-fed machine gun. It comes in the "Low Weight", "Storm", and "Suppressive" variants. Until the inclusion of the Browning M1917, it had the highest capacity out of all the light machine guns in the base game, holding 100 rounds (200 rounds for the "Suppressive" variant).
==Browning M1917A1==
The Browning M1917A1 water-cooled machine gun appears in the Turning Tides DLC for the Support class. It comes in two variants: the "Low Weight", which has no attachments, and the "Telescopic", which is fitted with a Warner & Swasey scope. Both variants are equipped with a 250-round belt box. The A1 variant was developed in the 1930s and is anachronistic for the WW1 time period. 
==Burton 1917 Light Machine Rifle==
The Burton 1917 LMR (Light Machine Rifle) was added to CTE testing in June 2018 and later to the base game in the same month. It is used by the Support class. Another obscure prototype weapon, the Burton's unusual two-magazine design is reflected in its unique gameplay properties. In gameplay, the two magazines are tracked individually and treated as distinct "fire modes", with a press of the fire mode key resulting in the player character switching between the two magazines, pulling one out and slapping the other one in. Each magazine has its own reload animations, and pressing the reload key only reloads the currently active magazine.
Adding to the two-magazine gameplay is the ammunition. Designed as a dual-purpose aircraft gun with the ability to switch between normal rounds and incendiaries for targeting observation balloons, the in-game weapon has the right magazine using regular rounds, and the left magazine using incendiary rounds. The incendiary rounds do not light anything on fire, and merely changes the damage model to be more effective against planes but less effective against infantry.
Lastly, the in-game weapon features the "ground" barrel with its bayonet lug, allowing players to use a bayonet on it, a first for a Support weapon.
==Chauchat Mle. 1915==
The Chauchat Mle. 1915 Light Machine Gun appears in the They Shall Not Pass DLC. In-game, it has the highest damage model of all of the Support class's machine guns, at the cost of a low rate of fire (still 50% higher than the real weapon's; 360 RPM in-game versus the real steel's 240) and a mere 20-round capacity, though this is likewise one more than the real weapon, which would almost always fail to feed the first round from a full magazine and was usually only loaded with 19 rounds.
==Hotchkiss Mle. 1909==
The Hotchkiss M1909 light machine gun is one of the first Support class weapons, labeled as the "M1909 Benét-Mercié." The reloading animation for the non-empty reload is inaccurate; the player character simply shoves the feeding strip as if nothing was retaining it in the first place.
For completion of the Battlefield 1 Singleplayer, the player will be awarded "Trench Cleaner", a skin for the M1909 Benét-Mercié that is usable in Multiplayer.
==Huot Automatic Rifle==
The rare Huot Automatic Rifle is available for the Support class. One gun for each class requires reaching max level with the class (Level 10), whereas every other gun and variant is unlocked by Level 3; the Huot is the Support's Level 10 gun. There are two variants available in-game, the "Low Weight" and "Optical" variants, though the Optical variant was exclusive to the War Stories until the Spring Patch on April 28, 2017, which added it as an unlockable to multiplayer.
The Huot is portrayed as functioning as a closed bolt-system and tracks +1 in the chamber; in reality, it functions in open-bolt form.
A note is that the foregrip on the Optical variant isn't actually used (though its effects apply), as there is no easy way to animate the soldier's left hand gripping onto it, not with the already awkward ergonomics.
==Lewis Gun==
The Lewis Gun is the first light machine gun available to the Support class. It comes in the "Low Weight," "Optical," and "Suppressive" variants. The latter is equipped with a 97 round pan magazine, although it visually still uses a 47 round one.
thumb|none|450px|Lewis Gun - .303 British
==M1918 Browning Automatic Rifle==
The World War I version of the Browning Automatic Rifle is available to the Support class in-game. It comes in three versions: "Trench," "Storm," and "Telescopic." The HUD icon shows it equipped with the World War II-era hinged bipod at the end of the weapon; this bipod is also present on the "Telescopic" variant.
The weapon features a bonus weapon variant for pre-ordering Battlefield V, called "BAR M1918A2". The latter does have an M1918A2-like handguard and bipod and a usable fire rate selector, but still has the original M1918's stock, as well as lacking the new magazine guide.
==Madsen==
The Madsen is available to the Support class as the "Madsen MG". Originally, it was inaccurately depicted as a closed-bolt weapon with a +1 capacity, but this was later fixed. It comes in the "Low Weight," "Trench," and "Storm" variants. In the December 16th, 2016 patch, all the "Low Weight" machine guns were given bipods.
The Madsen in the game is anachronistically modelled on the port-war Portuguese contract model, which bears several features that were not present on any wartime Madsens, including a double-stacked magazine and a flash hider.
==Maxim MG08/15==
A German light machine gun variant of the famous Maxim heavy machine gun, the Maxim MG08/15, appears in the game. The weapon has exceptional recoil and shot spread when fired initially, but longer continuous bursts allow the weapon to settle and become more accurate provided the player character using it is not moving; crouching assists with this mechanic by making the length of a burst required for the recoil to settle down far shorter. The fact that the iron sights of the weapon cannot be used makes the above gameplay mechanic the only way to use the weapon accurately. 
In singleplayer the Maxim MG08/15 is the first weapon used by the Italian Arditi unit member Luca Vincenzo Cocchiola, the protagonist of the third "War Story" chapter, titled Avanti Savoia. Luca uses both the machine gun and body armor (of the WWI plate armor kind, with greatly exaggerated effectiveness compared to real life for gameplay) to accomplish the herculean task of storming his way up a mountain in the Italian Dolomites defended by the Austro-Hungarian army, all to protect his twin brother Matteo in a unit fighting nearby.
In multiplayer, the Maxim MG08 is available to any player character who can pick up a "Sentry Kit" from weapon crates that randomly spawn through a level. Mirroring Luca's exploits, any soldiers picking up a "Sentry Kit" in multiplayer are also automatically equipped with the same body armor Luca used, which makes them much more resistant to almost any form of weapon damage, but leaves the user unable to put on a gas mask and thus extremely vulnerable to in-game chemical weaponry. 
The weapon is reloaded with disintegrating belts in order to simplify the reload animation; though a disintegrating belt did exist for the MG08 during WWI, it was not standard, and standard ammo belts were non-disintegrating. At the time of the game's release, dynamic reloads like the ones seen on the Parabellum MG 14/17 were apparently not implemented into the Frostbite engine; some DICE comments on r/battlefield_live suggested that dynamic reload functionalities were added to engine after the game's release, around the time of In the Name of the Tsar.
==Maxim MG08/18==
The MG08/15's experimental air-cooled variant, the MG08/18 is available in the Apocalypse DLC, called the "lMG 08/18" with a lowercase L. It was originally called "LMG 08/18" during the CTE with an uppercase L. The case difference is notable as both were actual WWI German designations; lMG either stood for "leichte Maschinengewehr" (light machine gun) or "luftgekühlt Maschinengewehr" (air-cooled machine gun), according to different sources, while LMG stood for "Luft Maschinengewehr" (air machine gun; as in machine gun for use in the air i.e. plane-mounted MG). The MG08/18 is not known to be designated under either designation, so the originally CTE name probably was referring to how it's an LMG, light machine gun, though the current name is technically correct for both possible definitions.
Unlike the MG08/15, and like the MG 14/17 from the In The Name of the Tsar DLC, it is depicted with a non-disintegrating metal belt, and even features dynamic reload animations. In the /18's case, this is exhibited with the animation of the operation of the belt drum's hand crank, and how long the crank is operated to rewind the belt is dependent on how many rounds from the belt have been fired.
==Parabellum MG 14/17==
The Parabellum MG 14/17 appears in the In the Name of the Tsar DLC for the Support class. Interestingly, the weapon depicts the real weapon's non-disintegrating ammo belt, which comes into play during reloads. There are five different reload animations for different amounts of remaining ammo. Just a few shots, the player character will take out the reel and pull out the belt. More than that, the character will spin the reel (with up to three spins) to retract the cloth ammo belt before removing them. An empty reload shows the character simply detaching the belt from the gun and reload as usual. It boasts the fastest rate of fire in its class. It comes with two variants - "Low Weight" and "Suppressive".
==Perino M1908== 
The Italian Perino M1908 is the second weapon available in the In the Name of the Tsar DLC for the Support class. It comes in "Low Weight" and "Defensive" variants, both of which feed from an ammo box that holds up to six 20-round clips, 120 rounds in total.
=Flamethrowers= 
==Wechselapparat M1917==
The Wechselapparat M1917 appears in the game. In real life, it was the first flamethrower in history intended for, and capable of, being carried and operated by one man; disappointingly, it goes by the shorter name "Wex" rather than the original "Wechselapparat" moniker, depriving us all of the opportunity to hear people unfamiliar with German pronunciations stumble over the name. As with most flamethrowers in film and video games, the Wechselapparat is very short-ranged, cannot spread unignited fuel to create a flammable pool for later ignition, and is treated as having infinite ammunition despite the severely low fuel reserves mandated by weight considerations for man-portable flamethrowers. All this said, it does have considerably better range and damage than most video game flamethrowers, and the sounds it creates (initial ignition, flames themselves, and inevitable screaming) along with the flame effects make for a powerful and terrifying weapon to use or face.
In multiplayer, the Wechselapparat is available to all sides via the "Flame Trooper Kit" weapon crates that randomly spawn in multiplayer levels, and is always depicted as spraying a small amount of unlit fuel before the pilot light gets going, most likely for balance reasons. Players using this kit are also automatically equipped with body armor similar to but not as effective as that given to the users of the "Sentry Kit", presumably to allow Flame Troopers to weather some fire while getting close enough to use their primary weapon. 
In singleplayer it is never available to the player, but is seen right from the first "War Story" chapter "Storm of Steel" and the "Through Mud and Blood" chapter, always in the hands of enemy flame troopers who also wear body armor. The flame troopers in singleplayer do possess a weak point, however, as a few hits from any firearm to the Wechselapparat's back-mounted fuel tank is enough to always cause ignited fuel to spray out through the puncture, condemning the attached flame trooper to a flailing fit of screaming through his gas mask, shortly before exploding in a good-sized ball of fire.
=Flare Gun=
==Webley & Scott No. 1 Mk. III* Signal Pistol==
The Scout class can use a Webley & Scott No. 1 Mk. III* Signal Pistol, firing flares that either spot enemies close to them or blind any observers (a bit like a flashbang, but with a bit longer "flash", and no "bang"), but set enemies on fire on direct hit in either case. In other cases it's very common for users to light themselves on fire when the flare is fired in close proximity and enemies who run over the flare will take additional fire damage for a short duration. Notably, the weapon is never seen ejecting any casings; the rounds behave as though they were caseless.
The Turning Tides DLC added a third type of flare gun, the "Signal" variant, which is plated in either nickel or silver, has ornate engravings, and is exclusive to the new Infiltrator Elite Class. It has only one flare at a time, which automatically replenishes 60 seconds after use. The flares it fires make a distinctive sound, and glow green to friendlies while glowing red to enemies; they are also brighter than standard flares and emit small spark-like elements. In an example of something existing purely for gameplay, the flares can also be airbursted mid-flight by pulling the flare gun's trigger again, dropping the flare straight down. The location of the flare will then be the epicenter of a devastating artillery barrage, intended to be representative of calling in support from an off-map Dreadnought.

=Launchers=
==1.59-inch Breech-Loading Vickers Q.F. Gun, Mk. II==
The 1.59-inch Breech-Loading Vickers Q.F. Gun, Mk II, a rather obscure weapon designed for attacking enemy fortifications and quickly replaced in infantry use by the Stokes Trench Mortar, is a gadget available for the Assault class, serving a role similar to the rocket and missile launchers of previous games. Like the Tank Hunter's Mauser 1918 Tankgewehr, the gun can only be fired when its tripod is deployed.
It is referred to in the game as the "AT Rocket Gun," which is an error not entirely of the developers' making: due to the two flames emitted from holes in the base of incendiary shells for the aircraft-mounted version, it was popularly known as the "Vickers-Crayford Rocket Gun".
An Anti-Air version known as the "AA Rocket Gun" was tested in the CTE before the release of Turning Tides, but wasn't included in the retail version until the final release of the Apocalypse DLC.
==Blanch-Chevallier Grenade Discharger==
The Blanch-Chevallier Grenade Discharger, a prototype grenade launcher based on a Martini-Henry action, is available in the Turning Tides DLC as a primary weapon for the Infiltrator Elite Class (called Martini-Henry Grenade Launcher in-game). The weapon is shown correctly as essentially a rifle grenade launcher, firing proprietary impact-detonated grenades (different from the standard Mills Bomb) with .577-450 blank cartridges.
==Mauser Rifle Grenade Launcher==
The Medic class can equip their long guns with rifle grenade launchers resembling Mauser cup-type grenade launchers. They can fire Frag, HE, or Smoke rifle grenades. For gameplay purposes, they do not consume regular ammo inside the rifle when using.
==Grenade Crossbow==
A Grenade Crossbow is available for the support class. The Crossbow looks very similar to those that are used in the movie Capitaine Conan.
=Explosives=
An "interesting" mechanic in Battlefield 1 is that grenades (excluding the Geballte Ladung, which is a gadget) have no pin-pulling animations; the player character's right hand simply pulls out the armed grenade from offscreen and throws it, with only a very short delay between pressing the throw grenade key and the grenade flying out.
==Flachmine 17== 
The German Flachmine 17 Anti-Tank mine is available for the Assault class.
==Jam Tin Grenade==
A Jam Tin Grenade is used by the attacking faction when destroying a telegraph station in the Rush and Frontlines game modes. In an incredibly subtle detail, the label of the tin actually varies between factions, rather than just reusing one texture for all circumstances.
==Pétard Grenade==
The French Pétard Grenade is available in the Apocalypse DLC as the "Improvised grenade".
==Mk. I Limpet Mine==
The Limpet Charge shown in-game is primarily based on the Mk. I (MD1-7A) version of the Limpet Mine invented by British inventors Stuart Macrae and Cecil Vandepeer Clarke. Being a WWII mine, in reality, its appearance in WWI is anachronistic.
A tag present on the explosive designates it as the "Limpet Mine Mk. II", and says that it was manufactured in the USA by the "Wilkinson Armory Co." This is accurate as the real Mk. I limpet mine later became the Mk. II.
The Limpet Charge sticks to all surfaces regardless of their material, which is very clearly a gameplay decision; actual limpet mines are magnetically attached. It also is shown as detonating based on a standardized timer; the actual design had a detonation system based on a water-soluble pellet, which wouldn't allow for it to detonate in open air.
==Mk. V CN Gas Grenade==
The American Mk.V CN Gas Grenade appears as the "Gas Grenade".
==Mills Bomb==
The Mills Bomb is the common grenade for the Allied nations in-game. Appears as the "Frag Grenade".
==M1912 Lantern Grenade==
The Russian M1912 Lantern Grenade is available in the In the Name of the Tsar DLC, used by Russian factions under the name "Russian Standard Grenade," although in the menus it is still listed under Frag Grenade.
==Model 13/15 Kugelhandgranate==
The German Model 13/15 Kugelhandgranate is available in the In the Name of the Tsar DLC. It appears only as a melee weapon and is named the "Dud Club". It has a hidden chance to explode when hitting an enemy player, which can be as deadly for the user as the target.
==Model 15 Diskushandgranate==
The Model 15 Diskushandgranate appears as the "Impact Grenade".
==Model 17 Eierhandgranate==
The Model 17 Eierhandgranate appears as the "Mini Grenade." Prior to They Shall Not Pass the Model 17's main advantage was, unlike all other grenades, it was carried in pairs, meaning the player had more than one grenade to throw. However, following the first DLC, the player (should they survive long enough) now has access to functionally infinite grenades (as they operate on a cooldown timer), and can thus only carry one at a time. The mini grenade's small size makes it easier to throw further before it starts to drop without adjusting one's arc but at the cost of a significant decrease in damage.
==Model 24 Stielhandgranate==
The anachronistic Model 24 Stielhandgranate (identified by the lack of a belt clip on the head) is the standard grenade for the Central Powers in-game: this version, as the name suggests, was not actually available until 1924, with the Model 15, Model 16 and Model 17 Stielhandgranate being the appropriate WW1 variants. Appears as the "Stick Grenade".
thumb|none|350px|Model 24 Stielhandgranate
===Geballte Ladung===
The Geballte Ladung appears as a gadget used by the Assault class (referred to as the "Anti-Tank Grenade"). Note that is also the model for the anachronistic Model 24 Stielhandgranate instead of the accurate Model 16 or the Model 17. On promotional pictures, the Geballte Ladung is made of correct Model 16 Stielhandgranates.
==No. 2 Mk. 2 Hand Grenade "Hale"==
The British No. 2 Mk. II Hand Grenade "Hale" appears as the "Light Anti-Tank Grenade".
==No. 27 Smoke Grenade==
The British No. 27 Smoke Grenade appears as the "Incendiary Grenade".
==No. 37 Mk. I Smoke Grenade==
The smoke grenade is a British No. 37 Mk. I grenade.
=Mounted Weapons=
==37 mm Puteaux SA 1918==
The French Renault FT light tank has a 37 mm Puteaux SA 1918 single-shot, breech-loading cannon as its main armament on the first stage of armament.
==4 inch Stokes Mortar==
The Mark V tanks can be equipped with 4-inch Stokes Mortars.
==5.7 cm Maxim-Nordenfelt==
The A7V heavy tank is equipped with a 5.7 cm Maxim-Nordenfelt.
==6-inch Siege Cannon M1904==
Various 6-inch M1904 Siege Cannons are seen on eastern front maps.
==75 mm Blockhaus Schneider==
The "Light Howitzer Tank" variant of the Renault FT equips it with a short-barreled 75 mm Schneider BS Blockhaus Mortar.
==76.2 mm Putilov m/02==
A 76.2 mm divisional gun model 1902 is mounted on the Russian Armoured train and the Garford-Putilov Armoured Car.
==7.7 cm Feldkanone 96 n.A.==
The German 7.7 cm Feldkanone 96 n. A. can be used by the player. The gun is often near flag points and can only be controlled by one man instead of a crew of 5. In the single-player campaign Through Mud and Blood, the FK 96 can be seen with Buntfarbenanstrich 1918 camouflage.
==9.2 inch Mark I Siege Howitzer==
The 9.2-inch Mark I Siege Howitzer is available with the They Shall Not Pass DLC. Unlike the 21 cm Mörser 16 the player can use this Howitzer on the maps "Verdun Heights" and "Soissons" in the Operation mode and on "Caporetto" in the Conquest Assault mode. It fires explosive, smoke, and gas shells. In the first mission of "Avanti Savoia", a few unprepared Siege Howitzers can be seen at the beginning.
thumb|none|400px|9.2 inch Mark I Siege Howitzer
==15 cm SK L/45==
Several SK L/45 Coastal guns are mounted on the "Zeebrugge" multiplayer map.
==21 cm Mörser 16==
Fixed German 21 cm Mörser 16 heavy howitzers are seen around base areas in the multiplayer. In the single-player campaign, some British, German, and Ottoman NPC soldiers can be seen using the howitzers.
==38 cm-SK-L/45==
The Kaliber 38 cm, Schnell-Ladekanone, Kaliberlänge 45 (also called Langer Max, Long Max) can be seen on the map "Rupture". It cannot be used but it fires at regular intervals. In the "Nothing is Written" campaign the Railroad gun is mounted on the Ottoman armored train.
==Becker Type M2 20mm==
Becker Type M2 20mm is mounted on Zeppelins, Bomber aircraft, and Torpedo Boats in the game. Two stationary placements can also be found in the gondolas of a crashed airship on the map "Giant's Shadow".
==Canon de 75 mm modèle 1897==
The Canon de 75 mm modèle 1897 is mounted on the Saint-Chamond assault tank. 
==Granatenwerfer 16==
A Granatenwerfer 16 is available as a gadget for the Support class and comes with two variants, an Airburst version ideal for Infantry but dealing minimal damage to vehicles and a High Explosive (HE) variant ideal for enemy armor but dealing less splash damage to infantry. 
==Hotchkiss Mle. 1914==
The Hotchkiss Mle 1914 is mounted on the Saint-Chamond assault tank and Char 2C Super Heavy Tank.
==Lewis Gun==
The British Mark V tank incorrectly has a Lewis Gun mounted on the bow, which can be used by the driver; in real life, there would be a separate gunner for the machine gun mounted here. Lewis guns were mounted on previous Marks of British tank, but the Mark V used Hotchkiss guns instead. Mark V tanks seem to be used by both sides, which is actually accurate; huge numbers of tanks were abandoned following failed advances and pressed back into service with German forces.
thumb|none|450px|Lewis Gun - .303 British
==Lewis Mk. II Aircraft MG==
Lewis Mk. II Aircraft MGs are mounted on British planes.
==Livens Projector==
The Livens Projector is a stationed poison gas weapon on the "Caporetto", "Passchendaele" and "River Somme" maps. It is also called Gaswurfminen near Austrian and German positions.
==lMG 08/15==
lMG 08/15 machine guns are mounted on German planes like the Halberstadt Cl. II and Gotha bombers.
==Maxim Gun==
Fixed Maxim machine guns are mounted around the multiplayer maps. These are shown fitted with a Russian-style ribbed water jacket. Maxims are also mounted in cupolas on top of the Airship Behemoth (an R-class zeppelin).
===Maxim M1910===
A pair of M1910s are mounted on the Garford-Putilov Armoured Car.
==Maxim MG08==
The German A7V tank is equipped with a 57mm main gun and a number of Maxim MG08 machine guns that can be used by the crew. As with the Mark V, the A7V is shown being used by both sides, which is a little less likely since only 20 were built (Generalquartiermeister Erich Ludendorff was disinterested in tanks, declaring them to merely be a "nuisance") and the British and French already had tanks that were superior to them.
==Maxim QF 1 Pounder "Pom-Pom"==
Maxim QF 1 Pounders appear in certain fixed locations on maps.
==Obukhovskii 12"/52 Pattern 1907 Coastal Gun==
Some Obukhovskii Coastal Guns can be used on the maps "Albion" and "Cape Helles". In reality, the Ottomans used German 28 cm SK L/40 guns during the defense of Cape Helles.
==Ordnance QF 4-inch gun Mk. IV==
Several QF 4 Mk. IVs are mounted on the L-Class destroyer and the disabled HMS Vindictive on the "Zeebrugge" map.
==Ordnance QF 6-pounder 6 cwt Hotchkiss==
The Mark V tank is armed with two Ordnance QF 6-pounder 6 cwt Hotchkiss guns.
==QF 13-pounder 9 cwt==
The Quick-Firing Enfield QF 13-pounder 9 cwt can be equipped on the Artillery Truck.
==Parabellum MG 14==
Parabellum MG 14s are mounted on Halbterstadt and Gotha planes. In the last mission of "Friends in High Places", the German Zeppelin is armed with a pair of them. Unlike the later-added infantry MG 14/17, the non-disintegrating belt is not depicted; the belt simply disappears into the gun. 
==Vickers Mk. I==
Vickers Machine Guns are mounted on British Pattern 1914 Rolls-Royce Armoured Cars and Italian FIAT-Terni Armoured Cars, which were mostly equipped with Fiat-Revelli M1914 machine guns. The Mark V "Black Bess" in the campaign is also armed with a Vickers.
