Silencer

The (also known as Suppressor) is a weapon attachment available in every main game since Call of Duty 4: Modern Warfare, as well as appearing in Call of Duty: United Offensive, Modern Warfare 2: Ghost, Call of Duty: Black Ops (Nintendo DS), Find Makarov, Call of Duty: Black Ops: Declassified, Call of Duty Online, Call of Duty: Modern Warfare Remastered and Call of Duty: Mobile.
This attachment prevents gunfire from showing up on enemy minimaps and makes it harder to hear and locate the position of the shooter. It also reduces the muzzle flash of the weapon. As a disadvantage, the Silencer either reduces the range at which weapons do their maximum damage, damage of the weapon as a whole, or the damage done by the weapon at its longest range depending on what weapon the Silencer is used with.
==Call of Duty: United Offensive==
The first use of silencers in the Call of Duty franchise were in the Sicily levels of Call of Duty: United Offensive. A silenced Sten was the only default weapon James Doyle started with. He can acquire weapons from dead German soldiers, but the silenced Sten is given so the player can get up to the fortifications without alerting any enemies present. Ironically, all fire from the German weapons fail to alert any of the enemies, even though their arms do not use silencers.
If the player ends the first Sicily level with the suppressed Sten, it returns for the next level. However, it is very difficult to complete the mission with only the silenced Sten as the player cannot use the ammo from the MP40s, even though they share the same ammo magazines. However, it can be kept as a secondary weapon, using any captured German gun as a primary.

===Campaign===
Silencers are attached to the USP .45 in "All Ghillied Up", "One Shot, One Kill", "Ultimatum", "All In", "No Fighting In The War Room", and "Mile High Club", the MP5 in "Crew Expendable", "Ultimatum" and "Mile High Club", the M4A1 SOPMOD in a majority of MacTavish's missions, the M21 in "Blackout" and "All Ghillied Up", and the P90 in "All Ghillied Up".
In stealth-based missions, such as "All Ghillied Up" and the start of "Blackout", the silencer is necessary in order to kill with the player's gun. If using an unsilenced weapon, the enemies will be alerted, and at most, can lead to the player's failure of the mission.
===Multiplayer===
Silencers can be used on all pistols except the Desert Eagle and the BR9 in the remaster, assault rifles except the MP44, and submachine guns. When a player fires a weapon without a silencer, they will temporarily appear as a red dot on the mini-map to enemy players. Firing a suppressed weapon will not cause the player to appear on the mini-map in this fashion. The silencer also reduces shot volume and muzzle flash. Note that a suppressed weapon grants no amnesty from the UAV Recon.
The "invisibility" afforded by the mini-map is invaluable for flanking or ambushing. Even when enemies are alerted to the player's presence, they must either call a UAV or make a visual in order to locate the player. Along with the reduced shot loudness, this makes it much more difficult to locate, and furthermore track, the player's movements.
The major disadvantage of the silencer is the reduction in damage over range. Damage over range is reduced to about 70% of its original value for submachine guns and pistols, and to less than 50% for assault rifles. It should be noted that at a 25m range and beyond, bullets from a suppressed assault rifle will be dealing their minimum damage, while an unsuppressed assault rifle will still be dealing maximum bullet damage. This emphasizes the use of silencers as a close to mid-range attachment.
Despite the range penalty, powerful and loud weapons such as the AK-47 or the M14 can become somewhat more manageable with a silencer in certain situations. Such weapons are often plagued with being a combat magnet from the range at which they can be heard firing. With a silencer, they become particularly devastating at mid range due to the stealth and sheer power.
When equipped on the G3, the weapon suffers from a bug with the lunge melee attack. Instead of the usual 0.13 second delay, the delay is 1.3 seconds from the animation completion to the damage dealt. The slash melee attack is unaffected, however. When equipped on the MP5 (excluding some Weapon Kit variants), the weapon undergoes a model change, as the barrel is changed to an integral suppressor variant of the MP5, the MP5SD. Model changes also occur with the Lynx CQ300 in the remaster.
As the only thing which can reveal a player on the radar while using suppressed weapons is a UAV, the UAV Jammer Perk is an obvious choice for those who wish to take the pure stealth option. A silencer with a UAV Jammer class can easily cause chaos in the rear lines of the enemy ranks. Attaching a silencer without the UAV Jammer is more risky than choosing UAV Jammer without a silencer, as if an enemy player acquires UAV Recon, the player using the silencer will suddenly be revealed, taking the stealth effect provided by the silencer away. Therefore, on larger matches, it is preferable to either take both or just the UAV Jammer, as a well-timed ambush can kill many enemies in a short space of time, negating the need for a silencer as the impending threat of the enemies is removed. As an alternative, a suppressed pistol can be used, acquiring kills without alerting the enemy team of the user's location.
Flanking the enemy may also be an effective technique, achieved by use of Extreme Conditioning. Dead Silence may also be an effective choice, particularly in Search and Destroy, where players often tend to listen carefully for enemy footsteps.
The Silencer attachment is unlocked for completing Marksman II for submachine guns and assault rifles, except for the MP44, which cannot accept attachments. The attachment is automatically unlocked for pistols when the pistol itself is unlocked, excluding the Desert Eagle and the BR9, both of which cannot accept a silencer.
Silencers are available on the USP .45 for the default class Spec Ops, and for the M9 on the default class Sniper.

==Call of Duty: World at War==
Working in the same fashion as their Call of Duty 4: Modern Warfare counterparts, the suppressor can be attached to the Gewehr 43 and all submachine guns except the PPSh-41. All the other rifles can attach a Flash Hider, which performs similarly to the suppressor. Oddly, the Gewehr 43 with the suppressor attachment will have the same reload animation for mid-magazine reloading as empty magazine reloading. The reload at mid-magazine is hastened so that it takes the same amount of time as a normal mid-magazine reload, but if the entire magazine is spent, it will reload as slow as it normally would. Enemies will have difficulty finding the player's exact position if he catches him off guard. Missed shots are also less detrimental with the suppressor, as the enemy will have more difficulty telling where the shots came from, however they will still hear the crack of the bullets flying past them and see the tracer shots. 
Unlike Call of Duty 4: Modern Warfare, pistols do not have suppressors and they cannot be unlocked.

==Call of Duty: Modern Warfare 2==
Silencers return in Call of Duty: Modern Warfare 2 as an attachment for all weapons, with the exception of launchers, the Riot Shield, .44 Magnum, Desert Eagle, Ranger and Model 1887.
Submachine Guns, Pistols, and Machine Pistols suffer the least from equipping a silencer, as there is only a slight reduction in range with no reduction in base damage, so this attachment is highly recommended. Assault rifles suffer a considerable range reduction, but do not suffer a reduction in base damage. Silencers reduce Sniper Rifle base damage values from 70 to 50. Without Stopping Power, it will always require at least two shots to kill an enemy with any suppressed sniper rifle. Silencers also reduce base damage values by 10 on Light Machine Guns. Shotguns suffer an extreme reduction in range when using silencers, and are considered unusable by most players. The one exception to this is the Striker, which suffers much less of a range penalty than other shotguns when equipped with a silencer.
Due to a glitch, the silencer does not properly work on MG4, M240 and M9, as firing will still result in radar detection. However, it still affects noise and muzzle flash, but given it reduces the damage for MG4 and M240 and range for M9, its usage is questionable.

==Call of Duty: Black Ops==
===Campaign===
The suppressor appears on the AUG and the M1911 (if switched, before being replaced by the Crossbow later on) in the mission "WMD". It also appears on an FAL and a Skorpion in the mission "Operation 40", as well as being used by Carlos on his M16 when on the plane.
===Multiplayer===
The Suppressor will reduce the range of Assault Rifles, SMGs, and Handguns when equipped, with each weapon getting a varying degree of range penalty. Any weapon with unique range values for its category will have slightly different damage drop-offs.
Sniper Rifles, like in previous games, will receive a base damage reduction. All sniper rifles will deal base fifty damage per bullet instead of base 75 damage per bullet, with the damage multipliers being unchanged. With how the damage multipliers are set up for the sniper rifles, this means that all sniper rifles will only be able to get a one shot kill to the head and neck in Core game modes. This makes the L96A1 and PSG1 very unsuitable for suppressed use, as their damage advantage over the Dragunov and WA2000 is completely negated.
On the SPAS-12, no range or damage reduction is done, making the Suppressor a pure benefit on the SPAS-12.
Certain weapons in each category do not have access to the suppressor. For assault rifles, the G11 cannot equip a Suppressor. Among SMGs, the PM63 cannot use a Suppressor. Among pistols, the ASP and Python cannot be suppressed. No other shotgun has access to the Suppressor.
As it does with any other attachment, equipping the Suppressor on the CZ-75 will make its switch speeds slower, making the CZ-75 less suitable for those who need good switch speeds on their suppressed handgun.
In the Nintendo Wii version of Call of Duty: Black Ops, the Enfield, Galil, AK47, and Commando have their fire rate reduced from 750 RPM to 625 RPM when equipped with a suppressor.

Suppressors are first seen on two weapons, the M14 and integrated into the Mk 22 Mod 0, though it is also available for the Dragunov, the PPSh-41, the Makarov PM, the M40 and the M10. It will prevent enemies from reacting to the player's shots, and keeps the player off the radar in multiplayer when shooting.

==Call of Duty: Modern Warfare 3==
The silencer reappears in Call of Duty: Modern Warfare 3 and was first spotted in the first reveal trailer being sported by several MP5s.
===Campaign and Special Ops===
It can be seen on some AK-47s, with or without the ACOG Scope or Grenade Launcher. The silencer can also be found on other weapons in the campaign, as well as weapons that the player starts off with. It can be found on starting weapons in missions such as "Mind the Gap" and "Eye of the Storm".
The silencer is also found in Special Ops, but only in mission mode. There is basically no difference in gameplay with the attachment when in campaign or Special Ops. The silencer can be found in missions including "Resistance Movement" and "Invisible Threat".
===Multiplayer===
In multiplayer, it can be used on nearly all the weapons with the exceptions of Launchers, the Model 1887, revolvers, and the Desert Eagle. It is unlocked at Weapon Proficiency Level 2 for Pistols and Machine Pistols, and Weapon Proficiency Level 5 for every other weapon. It behaves similarly to the previous versions, making the player not appear in the mini-map when firing, reducing the muzzle flash, sound and reducing the minimum and maximum range of the weapon by 25%. Suppressed sniper rifles have their base damage reduced by 28.57% at all ranges as in previous games. Silenced Light Machine Guns are still able to kill in three hits or less under normal circumstances, causing little detriment other than the opportunity cost of not using another attachment.

==Call of Duty: Black Ops II==
The Suppressor returns in Call of Duty: Black Ops II.
===Multiplayer===
Like in previous games, when the player fires a weapon with a Suppressor, they do not appear on the mini-map as a red dot, giving a stealth advantage. In addition, the shots are quieter and the weapon's muzzle flash is removed; however, using the Suppressor results in a loss of range. This is not the case for sniper rifles; instead their damage multipliers are modified, meaning fewer one-shot-kill areas. 
On the assault rifles, SMGs, and LMGs, range values for the weapons affected are reduced by thirty percent. On shotguns and pistols, however, the range reduction is much less severe, reducing range by only ten percent. Even with the significantly reduced range penalty, the Suppressor is still a very dangerous attachment on pellet firing weapons and the KSG, as they have a finite range, and the Suppressor will effectively reduce the range at which these weapons can hit anything at all. On bullet firing pistols however, the Suppressor is a much more intriguing attachment than normal to use due to its very small range penalty on them. 
The range penalty the Suppressor confers can be stacked with the range reduction penalty of Rapid Fire to reduce range even further. When the two attachments are combined on an LMG, the LMG in question will have 58% shorter range values. Most SMGs with such an attachment combination will have 72% shorter range values, whereas the Chicom CQB and Skorpion EVO will have 82.5% shorter range values since they get a more severe range penalty from Rapid Fire.
For the SVU-AS, the headshot multiplier is removed, preventing the SVU-AS from outright killing any enemy at 100 health in one shot in core game modes. For the DSR-50, the lower abdomen/stomach multiplier is removed, making its one-shot kill report identical to the Ballista and the XPR-50 without a Suppressor. The Ballista and the XPR-50's upper abdomen/chest multipliers are removed when using a Suppressor. The DSR-50, Ballista, and XPR-50 will all lose the ability to score a one shot kill to the forearms as well when the Suppressor is equipped in Core game types, making shots to the arms less consistent at getting one shot kills. The change in one shot kill areas is almost irrelevant in Hardcore game types, as the Sniper Rifles deal more than enough base damage to score one shot kills, with them even able to get one shot kills through moderately thick cover. 
It also reduces center speed by two percent, resulting in a very slight recoil increase. On the SVU-AS, however, the centerspeed is reduced by ten percent, making the SVU-AS' recoil slower to settle. If combined with the Dual Band Scope, the centerspeed is reduced by 14.5%, making the SVU-AS considerably slower to re-center between shots.
To prevent compensation for the range loss, Long Barrel is not available when using a Suppressor.
===Zombies===
The Suppressor appears in Zombies with a limited role: it can be obtained on the DSR 50 as one of the attachments gained when repeatedly Pack-a-Punching the weapon. It is also acquired on the Mauser C96 when Pack-a-Punched. Unlike in multiplayer, the attachment gives no stealth bonus at all, other than the reduced muzzle flash (which is arguably not a notable trait due to muzzle flash not showing when scoped in) and instead occupies one of the possible attachment slots, making it a rather bad final attachment choice.

==Call of Duty: Ghosts==
The silencer returns in Call of Duty: Ghosts. It prevents the player showing up as a red dot on the radar when firing, and reduces noise and muzzle flash of the gun in exchange for reducing range by 25% (or multipliers on Sniper Rifles). An interesting thing in the game code is that every weapon class has a separate code where it says the percentage of range lost. This means that in the future Infinity Ward will be able to change the effect of the silencer separately for each weapon class. The silencer has a different effect on sniper rifles; the multipliers of the weapon are changed so that the player gets fewer one shot kills to certain parts on the body. The Honey Badger, K7, and VKS have integral silencers, meaning that those weapons have the effects of the silencer as default instead of an extra attachment option, and those weapons don't have access to the Flash Suppressor, Muzzle Brake, or Chrome Lined.
Due to how typical gunfights take place at a longer distance than in other Call of Duty games, the Silencer can be a very risky attachment to use on Assault Rifles, LMG's, and Marksman Rifles due to the range penalty those weapons receive, and how those weapons strive at medium to long ranges. The attachment works best on close range weaponry in Ghosts, as it helps improve flanking and stealth strategies, which are useful with closer ranged weaponry.
The Silencer is unlocked by default for the P226 if one of the player's soldiers has the default stealth loadout, which includes a Honey Badger.

==Call of Duty: Advanced Warfare==
The suppressor returns in Call of Duty: Advanced Warfare. It prevents the player from being shown on the mini-map when firing, but reduces range by 25% (Damage will be reduced by 25% for Sniper Rifles). It can be countered by the Parabolic Microphone. Directed energy weapons like the EM1, Tac-19, and AE4 do not have access to the Suppressor. The Suppressor is also unavailable to the NA-45, Atlas 20mm, and the Blunderbuss.
Using the Suppressor restricts access to the Advanced Rifling attachment as to not counteract the Suppressor's range-reducing effect.
Due to the inclusion of exo movements in Multiplayer, flanking can be made a lot easier, and stealth strategies can be more potent than in previous games, making the Suppressor quite valuable in certain situations.
The IMR Hushed and the S-12 Quiet Time have integral Suppressors, restricting complete access from Advanced Rifling on those two weapons.
In the campaign mission "Aftermath", the suppressor on the Bal-27 is equipped with an integrated flashlight.
In Exo Survival, on the map Riot, the suppressor can be seen in the ending cutscene, as well as the Outbreak map opening in Exo Zombies. After an update, it is now also used by enemy Cloaked soldiers after the map is flipped.

==Call of Duty: Black Ops III==
The Suppressor appears in Call of Duty: Black Ops III. This iteration of the Suppressor allows the Long Barrel to be equipped in conjunction with the Suppressor to somewhat counteract its range penalties.
The attachment works differently based on the weapon category, with a few exceptions:
*All assault rifles except KN-44 and MX Garand receive a 65% range reduction
*KN-44 and MX Garand receive a 30% range reduction
*All LMGs receive a 90% range reduction
*All pistols and submachine guns receive a 30% range reduction
*KRM-262, 205 Brecci and Haymaker 12 receive a 30% range reduction, although minimum damage range is unaffected
*Argus receives a 10% damage decrease per pellet
*Sniper rifles, Rift E9 and Banshii receive no penalties due to their lack of damage drop-off

==Call of Duty: Infinite Warfare==
The Suppressor returns in Call of Duty: Infinite Warfare, occupying the same usage as its predecessors. It features a separate model for energy weapons to distinguish between the bullet types. It is also integral to Synaptic's Equalizer payload, the Widowmaker Smoke variant via the SBD gun perk, the VPR Yokai variant via the Assassin Build gun perk and the NV4 Honey-B variant.
===Zombies===
The suppressor is available as an attachment for weapon loadouts in Zombies. It has the unique function of drawing attention away from the player, making it possible to damage and kill zombies that may be chasing a teammate.
This becomes especially useful in higher co-op rounds, as a suppressed Baby's Breath can eliminate a horde of zombies without the player ever being detected, and the same can go for primary weapons.

==Call of Duty: WWII==
===Campaign===
The Suppressor is compatible with the Grease Gun, P-08, and 1911 respectively in the levels "S.O.E.", "Liberation", and "Ambush". The player can attach or detach the supressor at any time.
===Multiplayer===
Initially, the Suppressor was available as a Division Skill for the Airborne division in multiplayer, and was only compatible with submachine guns. 
On April 10th, 2018, the Suppressor was removed from the Airborne division and became an attachment for all submachine guns and pistols with the Divisions Overhaul. The De Lisle and SDK 9mm sniper rifles also come with integrated (non-detachable) suppressors.
Like in the campaign, the Suppressor can be attached or detached at any time; this ability is only limited to submachine guns, however. Leaving it on outside of close ranges or in a face-to-face gunfight is ill-advised, as it reduces range on all SMGs by 30%, a big penalty. And a 15% range reduction on pistols.
Stacking Advanced Rifling with a suppressor will have a net penalty of 9% to the weapon's range.

==Call of Duty: Black Ops 4==
The Suppressor reappears in Call of Duty: Black Ops 4, retaining the same use as its predecessors. It is available to be put onto weapons in Multiplayer, Zombies, and Blackout.
==Call of Duty: Modern Warfare==
Multiple different suppressors are present in Call of Duty: Modern Warfare (2019) including the Lightweight Suppressor, Tactical Suppressor, Monolithic Suppressor, among others.
==Call of Duty: Mobile==
The Suppressor returns in Call of Duty: Mobile as a single weapon attachment prior to Gunsmith update. In Season 9: Conquest following the introduction of Gunsmith system, there are variations such as OWC Light Suppressor, Tactical Suppressor, Monolithic Suppressor, Agency Suppressor and more.
In Battle Royale, a variation called the "Shotgun Suppressor" can be found in support drops. However, this was removed along with the separate attachments in Season 9: Conquest.
== Call of Duty: Black Ops Cold War ==
The Silencer, Suppressor, and Sound Suppressor all return in Call of Duty: Black Ops Cold War. With Assault Rifles and Light Machine Guns getting Suppressors, Tactical Rifles getting Silencers and Sound Suppressors being given to Submachine Guns, Pistols and Shotguns. All give the same upside of total muzzle flash and sound concealment, however, each one has differing downsides, with Silencers having reduced bullet velocity, Sound Suppressors having reduced range, whilst Suppressors have both of the downsides.

Multiple different suppressors are available including the XTEN RR-40, Forge DX90-F, SA Schalldampfer 99, Singuard MKV, and many others.
==Call of Duty: Black Ops 6==
The Suppressor returns in Call of Duty: Black Ops 6, functioning primarily like it's counterpart in Call of Duty: Black Ops Cold War. While the main advantage all around is the suppression nature of the muzzle attachment, within Multiplayer, it also removes the ping notification that firing an un-suppressed weapon produces. However, in Zombies, while this effect is still present, the additional effect of the undead having a chance to drop extra salvage is added.
==Trivia==
===General===
*Shooting a weapon with the silencer attached will reduce the vibration of the controller if it is enabled.
===Call of Duty: Black Ops===
*Equipping a suppressor to the M14 would make tracer rounds invisible before an update.
===Call of Duty: Modern Warfare 3===
