KM-8 Gran, (КМ-8 "Грань" - "Borderline"), is a Russian 120mm guided mortar weapon system. It uses the Malakhit semi-active laser guidance fire control system to perform top attacks, and is able to attack moving and stationary targets.

Several mortars using this system can fire simultaneously without interfering with each other. The system uses common data for targets spaced at up to 300m. Gran projectiles can be fired from smoothbore and rifled mortars.
