JEMS is the updated MBITR. 3 pound radio that works on multiple band width. SATCOM and SINCGARs primarily for me. I could talk with fixed wing, my local units and probably the Taliban if I knew what I was doing (which I really didn't)
A 7 banger is a flashbang that goes off 7 times (about 1 "bang" per second). More distracting than a single shot, though heavier. I don't do Hostage Rescue, so I throw one in if I am not sure if bad guys or not. I know what the noise is, unknowns don't. Mutliple uses when things are going wrong.
My assault bag had more ammo, smokes and some target designation stuff.
More goo packs and jerky, too.

Sorry about the confusion.
