R.P.G (Rocket propelled grenade) with full details

A rocket-propelled grenade (often abbreviated RPG) is a shoulder-fired anti-tank weapon system that fires rockets equipped with an explosive warhead. Most RPGs can be carried by an individual soldier. These warheads are affixed to a rocket motor which propels the RPG towards the target and they are stabilized in flight with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPGs, with some exceptions, are generally loaded from the muzzle RPGs with high explosive anti-tank warheads (HEAT) are very effective against armored vehicles such as armoured personnel carriers (APCs). However, heavily armored vehicles from the 2010s, such as main battle tanks, are generally too well armored (with thick composite and/or reactive armor) to be penetrated by an RPG, unless less armored sections of vehicle are exploited. Various warheads are also capable of causing secondary damage to vulnerable systems (especially sights, tracks, rear and roof of turrets) and other unarmored targets. The term "rocket-propelled grenade" is, strictly speaking, a backronym; it stems from the Russian language РПГ or ручной противотанковый гранатомёт (transliterated as "ruchnoy protivotankovy granatomyot"), meaning "hand-held anti-tank grenade launcher", the name given to early Russian designs.
