I wonder about that myself, can an individual officer or nco carry his own sidearm? The man I knew who carried it in WWII and Korea was a Sgt. He was a driver for an officer. He said he foiled an ambush when at least three "bad guys" tried to stop his jeep some where in Europe. He said his carbine was in it's rack and would have been too slow to retrieve. He got two and the officer got the last guy they saw, he didn't know if there were more running about, but he didn't see anyone else. The officer used a 32 colt. By the way this Sgt. said the officer switched to a .45 after that encounter.
