From my observations, in addition to the other posts:
Pelican flashlight 2400

Portable light table (if engineer)
I would not take a SLR camera as they tend to get banged around....buy the Olympus water/shock/freeze proof camera
Do not pack too many civilian cloths...just a few outfits
Lots of undershirts and skivvies
