What...no Burger King?

I read a news item yesterday that said the military is no longer supporting food (and other) vendors like Burger King, which have up until now sold their products to troops deployed in Afghanistan. The reason according to a senior NCO in the command? It's a war zone and no time for such things. The problem as I see it is the military has paid little attention to the proliferation of these sorts of morale support bennies over the past couple of decades. Now, troops have grown accustomed to having their Burger King or Pizza Hut available, even if it's sold out of a trailer in a war zone. Taking all that away will be a downer for sure.
