OCSW
Encyclopedia
The OCSW 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
