The RPG-18 Mukha (Russian: Муха, romanized: Fly) is a Soviet short-range, disposable light anti-tank rocket launcher designed in 1972.

The RPG-18 is very similar to the US M72-series LAW anti-tank rocket launcher, with captured examples during the Vietnam War likely being sent to the Soviet Union.

The RPG-18 fires a 64 mm PG-18 high-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.

However, performance is significantly lessened when the RPG-18 is used against targets protected by HEAT-resistant explosive reactive armour (ERA) or composite armor.
