Yep, a fair number of .mil and I'd say the overwhelming majority of police don't know diddly about their weapons. People think they do, but they don't.
The police thing I find especially interesting. True, they carry a handgun all day at work, but they hardly ever use it. They might fire it once a year for qualification or something. Meanwhile they use VHF radio communication devices, some rather sophisticated, every day and all day, but nobody thinks they're experts on such matters. Why people think they're experts on the things they never use is illogical. Especially when we see events, and I can't remember where this was, where 73 shots are fired, 2 hit the intended target, and 1 hits an innocent bystander.
