Universal Ammo System

A mod recently developed by V.Berlioz which solves the issue of most Arma 3 mods using different stats for different ammo types. Created as a counterpart to Advanced Armor Plate Mod, UAS brings in a wide variety of ammunition types from armor-piercing to frangible, from common to exotic.

Furthermore, it also adds wide suites of shotgun shells, grenades, 40mm grenades, launcher warheads, static explosive charges, and even vehicle munitions. Featuring an indepth system of simulation for ballistics external and terminal, this mod is perfect for those who wish to play with a highly realistic experience.

## **Quick Start: Infantry Ammunition**

UAS at first glance is a very complex mod. Many of the ammunition types featured in it are making their first debut to any video game. However, one can easily master the basics by sticking to what you know or starting out with a switchboard patch like UAS Lite. The latter option is covered in its own page, so the former will be covered here. Most mods typically have one type of ammo while more complicated ones will have a handful of bread-and-butter basics, such as 5.56x45mm M855, 7.62x51mm M118, 5.56x45mm M855A1, 5.56x45mm Mk262, and the infamous .50 Mk211 Raufoss.

UAS on the other hand is the foil to AAPM - a mod which seeks to capture the diversity and intricacy of real world body armor. Thus, UAS is packing quite more than a handful of ammo types. While the choices available may seem very complex, it becomes much easier if you find something familiar, and branch out from there. Here is a curated list of reasonable ammo types safe for use in any scenario along with basic descriptions.

#### 5.56x45mm NATO

Main page: 5.56x45mm NATO

* M193: 55-grain FMJ, used by the US Military during Vietnam and later conflicts. Replaced by M855 in the 1980s. M193 moves at a fairly high velocity and is highly capable of defeating velocity-vulnerable steel armor such as AR500. This round is popular with survivalists and civilians to this day, although it is certainly long in the tooth for military usage. Well-rounded and highly recommended for starter usage. The tracer version is M196.
* M855: 62-grain FMJ with a steel penetrator. Slower than M193 and notorious for underwhelming terminal ballistics, M855 is excellent for piercing polyethylene armor due to its harder steel core being very difficult for polyethylene plates to pancake. The tracer version is M856.
* M855A1: A potent fragmenting steel-core load that combines the strengths of M193 and M855. Robust terminal ballistics and capable of defeating most entry level body armor, M855A1 is the current-issue round of the US Army and serves very well in that capacity. The tracer version is M856A1.
* Mk318: A barrier-blind load adopted by the US Marine Corps. Great against windshields but not so hot against body armor. It nonetheless has good stopping power and is a good pick for fighting insurgents you need dropped quick.
* Mk262: 77-grain OTM developed for designated marksmen. Hits hard but sacrifices velocity and armor penetration. This won't penetrate any serious armor plates, but it still has the capacity to defeat typical soft armor such as NIJ-IIIA panels.
* M995: 52-grain tungsten penetrator. The most well known 5.56x45mm AP loading, M995 can challenge a large variety of common plates all the way up to some NIJ-IV models. Barrier penetration is superb and it can easily get through walls.

#### 7.62x51mm NATO

Main page: 7.62x51mm NATO

* M80: 147-grain FMJ, a loyal workhorse of the US Military. Six hits of this round is the required battery for all NIJ-III armor plates. Not the greatest penetrator, but barrier performance is alright. Stopping power is average. The tracer version is M62. Due to its all-around characteristics, M80 is the recommended starter round for 7.62x51mm.
* M80A1: Highly improved version of M80 with a lighter projectile, increased velocity, and superior penetration. Arguably on-par with .30-06 M2AP, M80A1 is replacing M80 in US service. The tracer version is M62A1.
* M993: Tungsten penetrator loading that is essentially a scaled-up M995. Capable of defeating NIJ-IV body armor up to 150 meters away, M993 has excellent penetrative abilities against anything up to light armored vehicles. Stopping power is a little lackluster, but not awful. This round is capable of defeating anything up to, but not including NIJ-V plates and their international equivalents. This round is a very safe bet for if plates are a problem.
* Swiss P AP: Dual core tungsten AP capable of beating NIJ IV armor plates at 350-325m range, made by RUAG. Extremely good at beating barriers and armor, terminal is sketchy, but it can challenge and win against XSAPI class inserts at approx 150m. Perfect for that armored suicide bomber in his up-armored Hilux.

#### 12.7x99mm NATO

* M33: The bread-and-butter FMJ loading. Strong performance and can brute force through most body armor. There are purpose-built plates capable of stopping it, however, such as the SARVIP. For defeating most barriers, getting through house walls, and most certainly eliminating targets with less-than-optimal shot placement, this is the answer. Recommended starter round.
* Mk211 Raufoss: An infamous combined-effects penetrator. On-par with M33 at defeating hard targets, Mk211 also has powerful incendiary and explosive effects that will bypass nearly all body armor with ease. Strongly recommended for engaging lightly armored vehicles, disabling cars, and engaging armored infantry. Recommended for taking shots at long range.
	+ MK300: Tracer variant.
	+ Mk211 F3: An improved, higher-penetration version
		- Mk300 F3: Tracer variant.
* M903: A tungsten-core SLAP load. Extremely penetrative and devastatingly so against armored targets. M903 moves at high speed, has a very flat trajectory, and will without question defeat the vast majority of body armor in AAPM's lineup. This is the most well-known of the Sabot Light Armor Piercing .50 caliber cartridges.
