PepperDog,
I assume you will be going through Ft. Benning CRC.
As a contractor you will be allowed two duffebags and a carry-on. That's it.
Also, you HAVE to be in the Contractor Verification System. If not they will not let you deploy. My CRC roommate was turned back becaues his company had failed to get him into CVS.

The bedding here sucks. You will need an extra set of sheets and a good pillow. My wife just sent me a matrass pad. I should have gotten one sooner. Some of the matrasses I've seen here look like they were bought second-hand from a Bangkok whore house. The pillows are like burlap bags of gravel. It's hit or miss at the PX, mostly misses. Shop at Target/Wal-Mart and get what you like and ship them to yourself.
Since you are limited to two duffel bags, I'd pack a couple of boxes of stuff you want to bring but can live without for a couple of weeks and mail it to your APO address. If you don't know exactly where you will be living, have your family mail them to you when you get in country.
Will you have a weapon?
