Lots of good suggestions here, but there's no point in buying any of it now, really, except for maybe some extra first-aid items (MB's suggestion of an Israeli tourniquet is a good one). You're not likely to be in an extended survival situation in the TRACOM/RAG.
Good point which I didn't mention in my previous post....I'm mostly looking for immediate action kinda stuff at this point since it would more than likely be less than a couple hours on the ground. Anyway, awesome suggestions gents, really appreciate the feedback. Keep em coming!
