Don't take too many civvies as you won't be needing them very much (PT kit notwithstanding). You may get a few days AT at the end depending on the needs of the BG. Pack as you would for an Op is the best advice I can give you. There is a MOB and some FOBs dotted round, some are semi decent but expect to live under a poncho too. Take 2 camelbaks if you have them as water supply can be a real issue. Take desert AND jungle boots as if you aint in the sand, you are in a quagmire.
