We are facing the same arguement between police officers / support staff. Get rid of the "useless" support staff and the officers can do their job. Very true but a PC on £32k doing the same job as a support staff on £15K. Yes more officers would needed (consquently a bigger wage bill) but not more officers on the street doing the job that the public want.
The same would be true with the military. So you get more military admin clerks, chefs, drivers but that still does not give you more front line soliders to do the fighting does it.
