... your kevlar?
Cleaning mine out I found the foam puss pad, 1 burlap sandbag, 1 partially filled out DA form 1156 (casulty feeder card)(both those by unit SOP), 1 map protractor, 1 GTA 7-1-31 (Infantry leaders refernce card), 1 NBC report cheat sheet, 1 pic of my GF, a pen, an old SOI cheat sheet from 2 years ago, a big feather of some sort, and a small pocketknife.
Whats in your helmet?
