The M136 AT4 BDM is the Army's primary light antitank weapon. It is a recoilless rocket launcher used primarily by infantry forces for engagement and defeat of armor threats. The design permits accurate delivery of a 84mm High Explosive Anti-Tank (HEAT) warhead providing excellent penetration capability and lethal after-armor effects.
The system weighs approximately 15 lbs and is man-portable. The AT4 system consists of a free flight, fin-stabilized, rocket packed in an expendable, one-piece, fiberglass-wrapped tube. The launcher is watertight for ease of transportation and storage. The M136 AT4's warhead uses an extremely destructive, 440-gram shaped-charge explosive that can penetrate more than 14 inches (35.6 cm) of armor.
It is a single shot, disposable munition that is usually used to destroy walls, gates, and Strykers. Tests have shown that this will function the same as the RPG, except it will have a larger blast radius and cannot be reloaded. Info subject to change.
In game, the AT4 will take two (2) shots to destroy the OpFor Stryker.
It has adjustable ironsights for ranges of 100, 200, 300, 400, 500 meters. The default button for this is the mousewheel.
