The **AT-4 CS** is an anti-tank weapon featured in *Squad*.

## General Information

The AT-4 is an 84mm unguided, single-shot anti-tank weapon produced in Sweden. It's intention is to give infantry units a way of fighting armored vehicles and fortifications, but is generally considered ineffective against modern Main Battle Tanks. The launcher and projectile are part of a single system which is discarded after a single use like the M72A7 LAW.

The AT-4 was developed in the mid-80s originally for use of the Swedish army. Even before the Swedish adoption of the system it already entered a US Army competition in 1982, where it came out as a winner and was adopted after some changes were made to it. It is now in use in many armies across the world, and the US has produced over 300,000 locally. The High Penetration version of the AT-4 is in very limited service with the British army under the designation of ILAW. ILAW stands for Interim Light Anti-Armour Weapon and is meant to fill the gap between the LAW 80 launcher and the new NLAW, a guided missile system.

## Variants

The AT-4 CS is available to three factions and features different warheads depending on faction:

### M136

As of Alpha 14, the AT-4 has been reworked significantly. In a US Army squad with two LAT kits, one kit will get an AT-4, and the other LAT will get a M72A7 LAW. The US HAT kit is now armed with an M3 MAAWS as its primary anti-tank weapon, replacing the AT-4. The US Army AT-4 penetration and damage values were nerfed as a result of its replacement.

Even with the nerfed base damage and penetration, M136 is still a powerful weapon against armored vehicle.

### ILAW

As of Alpha 14, the British Army used the AT-4 (the L2A1 ILAW - Interim Light Anti-Tank Weapon) as their primary Heavy Anti-Tank weapon. In contrast to the American AT-4, which was nerfed to Light Anti-Tank and then replaced, the British variant of the AT-4 was buffed to reflect the British Army using an upgraded variant with higher penetration.

The ILAW was replaced by NLAW in v2.0, and it's no longer available in the game.

## Gameplay

* Both variants are single-shot, disposable launchers that fire one round and are then discarded.
* The US Army, United States Marine Corps M136 AT-4 CS and the British Army ILAW AT-4 CS look almost identical in-game.
	+ They both have relatively short blast radii and lethal radii, it is not advised to waste AT-4 ammo on infantry.
	+ The American variant is weaker than the British one, having 960 base damage and 420 mm penetration. The British variant has 1248 base damage and 600 mm penetration.
		- Both are still formidable infantry-carried anti-tank weapons, especially in the right hands.
* Both variants are relatively short-ranged and use simplistic iron sights.
	+ Press `X` and then scroll with the mouse wheel to adjust the iron sights up or down.
* Two variants of the rocket have different minimum arming distances. For the M136 AT-4, it is 25 meters, while for ILAW, it is 40 meters.
	+ If you are too close to your target, the rocket will not detonate or deal any damage.
* When you reload your ammunition from an ammo crate, your launcher is not automatically ready to fire the next time you switch to it. You must switch to the launcher, finish the animation of discarding the old launcher, and then arm the new one.
* Armour calculation involves many factors that are not limited to simple base damage and penetration. The slope of the armor, its thickness, the angle of hit, all of that matter when the game engine decides if damage has been dealt to the target. Examine the vehicle armor models on Jensen's Range to learn where your shots will do damage.
