Strategypage has a lengthy post on the inversion of priorities:
Another ancient complaint is how the fobbits (the guys who rarely leave the FOBs, or Forward Operating Bases), hog all the goodies. Something good comes into the PX (the army version of a general store), and the fobbits scarf it up first. It's rare for a commander to be astute enough to make sure some of these goodies are put aside for the guys working outside the wire. Same with access to Internet Cafes, or any form of entertainment. The troops doing most of the fighting, are getting the least support when it comes to living conditions. While many troops have air conditioned, two person sleeping quarters, many are still in tents or barracks holding a dozen or more people. The lack of privacy, and envy of what the others have got, grates and annoys. The combat troops accept it when they know there is no choice (like in small temporary bases), but not when they see lazy commanders screwing them out of ignorance or indifference.
Mind you, I'm not ridiculing the support troops--I was a REMF, and in the Guard putting me even further to the rear--but not going outside the wire should be good enough of a reward without emptying the PX of the best stuff.
Commanders need to get on the ball. This should be an unacceptable situation.
