The OCSW (Objective Crew Served Weapon) was a U.S. Military arms program started in the 1980s that led to a hybrid smaller prototype automatic autocannon developed by General Dynamics Armament Systems. It led to the XM312 and XM307 designs.As a part of the SAMP (Small Arms Master Plan) program it had the same laser targeting system as the XM29 OICW but was intended to supplement the 40 mm Mk 19 grenade launcher and the .50 M2 Browning machine gun.
