Just a slight aside if I may. In the RVN we had a lot of weapons NOT on the TO&E to choose from. Early on I ended up with a nice under-folder AK-47 that I carried with me in the cockpit. Someone quickly told me that it was a bad choice as a survival weapon because if I ever went down and had to defend myself and crew with it the good guys might start shooting at it's sound. I immediately acquired an M-16 through unofficial channels.
