Rocket-propelled grenade

Shoulder-launched anti-tank weapon

A rocket-propelled grenade (RPG), also known colloquially as a rocket launcher, is a portable, reusable, unguided, shoulder-launched, anti-tank grenade launcher that launches rockets equipped with a shaped-charge explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target, stabilized in flight with fins.
