The AT4 (also AT-4) is an 84-mm unguided, portable, single-shot recoilless smoothbore weapon built in Sweden by Saab Bofors Dynamics (previously Bofors Anti-Armour Systems). Saab has had considerable sales success with the AT4, making it one of the most common light anti-tank weapons in the world.
The AT4 is intended to give infantry units a means to destroy or disable armoured vehicles and fortifications, although it is generally ineffective against current modern main battle tanks (MBT). The launcher and projectile are manufactured prepacked and issued as a single unit of ammunition, with the launcher discarded after a single use.
