Tom,
I don't think I made my point clear. Cut the civilian side of the equation. They cost more and IMHO get less done on a day by day basis.
As jnevis said moving to contractors ends up draining E-5 and up technical support troops from the force. There is always some friction when the contractor doing the same job in East Jibib is making 2 to 3 times the amount of money of the troop working next to him. I have worked with some pretty good contractors overseas but they were all in the military before making the jump. Many had 20 and out, but more than a few had bailed at 10-14 years.
If you go to the states it is very different. I have had to deal with some real brain donors in DC, Crystal City, Richmond, Mechanicsburg, Dugway, APG and San Diego. These folks did not know their job, your job or what was clear required under a contract or procurement. Not one of these idiots was in uniform.
