A rocket-propelled grenade (RPG) is a type of weapon that uses a rocket motor to launch a grenade at high speed. It is designed to penetrate armor and is commonly used in military conflicts. RPGs are typically shoulder-fired and can be operated by a single soldier, making them portable and effective against vehicles and fortifications. The most well-known RPG is the RPG-7, which was developed in the Soviet Union in the 1960s. It has a simple design and can fire various types of warheads, including high-explosive and anti-tank rounds. RPGs are widely used around the world due to their low cost and ease of use.
