In my experience, the Air Force was the least familiar/comfortable around loaded weapons whilst "down range."
I remember the Load Master on the C-17 I flew in on had a Beretta in a really nice drop down leg holster, no magazine in said weapon, and no ammo pouches on him any where.
The USAF SF I saw milling about trying to look official all had M-16A2s, no magazines, but lots and lots of pouches in which I'm sure they were squirrled away.
'Course, these were the guys wearing berets right off an active flight line, in addition to thier body armor. Everybody else was wearing either boonies or bear headed.
