Motley, One time my platoon and I were training with the USMC 2D RECON BN at Camp Lejuene, NC and we played what they called full court Combat Basketball.  Almost the same rules as basketball but the uniform was flak vests (think Desert Storm), boots, and a little more contact was allowed.  About 20 long minutes was all either side could take.  Nobody won but both sides limped away with a much better understanding of one and another.
