Very Tough Swedish AT4 Anti Tank Weapon Missile
The AT4 Anti Tank Weapon is a guided, portable, disposable, shoulder-fired recoilless anti-tank weapon of 84 mm (3.31 in) caliber manufactured by Saab Bofors Dynamics (formerly: FFV Ordance, later, Bofors Anti-Armour Systems). The AT4 Anti Tank Weapon is not actually a rocket launcher, because the explosive warhead is not driven by a rocket motor. In contrast, the AT4 Anti Tank Weapon is a smooth bore recoilless weapon (as opposed to a recoilless rifle, which has a rifled barrel). Saab has achieved considerable sales success with the AT4 Anti Tank Weapon, making it one of the most common light anti-tank weapons in the world. The AT4 Anti Tank Weapon is a variant used by the United States Army.
The AT4 Anti Tank Weapon is intended to provide infantry units with a means to destroy or disable armored fighting vehicles and fortifications, although it is generally ineffective against more modern main battle tanks (MBTs), especially tanks with reactive armour, unless the armored section the weaker ones are exploited. The launcher and projectile are manufactured packaged and released as a unit of ammunition, with the launcher being discarded after one use.
