M136 AT4 Light Anti-Tank Weapon (AT4)
The M136 AT4, the Army's primary light antitank weapon, is a recoilless rifle used primarily by infantry forces for engagement and defeat of armor threats. The rifle's design permits accurate delivery of an 84mm High Explosive Anti-Tank warhead providing excellent penetration capability and lethal after-armor effects. PM CCS discontinued purchase of the AT4 in favor of its newest iteration, the AT4 Confined Space system.
