The RPG-18 is very similar to the US M72-series LAWanti-tank rocket launcher, with captured examples during the Vietnam War likely being sent to the Soviet Union.[3][4] The RPG-18 has been succeeded by the RPG-22, a very similar design with a larger warhead.
Description
The RPG-18 fires a 64 mm PG-18high-explosive anti-tank (HEAT) warhead mounted on a small rocket able to engage targets within 200 meters. The warhead self-destructs six seconds after launch, placing a limit on range even if a sight was used that was effective with targets beyond 200 meters. The RPG-18 can penetrate up to 300 mm of conventional armor. However, performance is significantly lessened when the RPG-18 is used against targets protected by HEAT-resistant explosive reactive armour (ERA) or composite armor.
Unlike better known weapons, the RPG-18 requires only one operator because it is not reloadable. Assistant grenadiers are used to help reload the RPG-2, RPG-7 and RPG-16 systems.
