Haven't a clue. I was a flyboy. Our "things that go bang" were too big for slings.

It's the carry strap from one of the 2-quart plastic bladder canteens, found in both olive drab and desert tan.

FYI, my sweetie was a USAF avionics tech for the Pave Penny laser targeting pod in the A10, now made hopelessly obsolete by the LANTIRN laser designator and targeting pods. She too is fond of *things that go bang* that come from the sky, are too big for slings, and which you don't want to drop on your big toe.

I almost guessed that. I carried one of those in my helmet bag on the chopper. I still have it stashed in my pickup along with 4 MREs in case of snow, etc.
