Hope your training goes a lot better than mine did (desert warfare training, Ft. McCoy, WI, Dec-Feb.... ice, snow, -40 degrees F, and DCU's....joy....) safe flight, have a safe tour, and get back home.
If you don't get the chance to check back in; Don't forget earplugs for the long...16+_ hours... flight if headed to Kuwait. Maybe sleeping pill. Blindfold or similar.
Or, if like me and can't sleep on plane, iPod with tunes and extra batt packs. Deck of cards. Good book. That is a long, mind-numbing, trip.
Toss up whether chartered commercial plane or USAF transport is better. Seats in USAF plane suk.... but I've had comfortable flight laid out on top of the cargo before.... Black fleece from ECWCS helps.
