RDC,
Always depends on the your billet. (lodging) A tent, MRE's, and a hole in the sand to squat over is a totally different world than air-conditioned "hardback" tents, mess halls, and running water.
Try to find out first, it'll help. And ANYTHING can be mailed to Saudi if you're ingenious enough. ;)
Tell your brother-in-law "HooYaah!" and THANKS!
