Another item I forgot to mention; Backpacks!! I used a "patrol pack for the search I led. It had a camel back bladder and sufficient room for a roll of toilet paper, first aid kit and 2 MRE's, and a few small items.

It had no frame. An internal frame pack would have worked but and external frame pack (eg: ALICE Pack) would have been a disaster. An external frame in the dense brush and vines would have had to have been dropped within 20 feet, in my opinion, thus leaving behind the resources that the pack contained.
