From 500 yards, every Marine is accurate with a rifle. Attach the OKC-3S Bayonet, and the weapon becomes just as effective in close combat situations. Also a Marine's multi-purpose fighting knife, the OKC-3S is the weapon of choice when shots can't be fired. Every Marine receives bayonet training in the Marine Corps Martial Arts Program (MCMAP) and on the Bayonet Assault Course in Recruit Training.
