X-Quork - indeed there is a need for field living up at the front line for assualt helicopter operations, especially as that front line will be an ever changing and fluid demarcation. Expeditionary forward LUPs like Cobra in the Gulf being a prime example.
But that's very different from what is akin to pitching tents next to Heathrow's runways because the bean counters are too mean to pay for the Post House. There's no intrinsic need (unlike the expeditionary assault helicopter example) for such conditions in rear areas; people are being shafted purely due to budgetary meanness and for no critical military reason.
