Interesting how you left out the other facts in that very report like:
o Private security contractor personnel are not authorized to participate in offensive operations and must comply with specific USCENTCOM Rules for the Use of Force (RUF).
And in Iraq, only 12,284 are in security positions, 670 US citizens. Of the remaining, the 9,000 non Iraqi are employed by Sabre, out of Africa, and they work perimeter security on the remaining US bases. They are only authorized to fire in self-defense. This was negotiated by State through the UN to create the "coalition". The Iraqi security, of which 2005 are armed, provide security to the GOI.
Interesting also how this is an official report on an open source military (.mil) website. Clearly we are trying to cover this up from the public.
The remaining numbers include tens of thousands of people doing things like cleaning up rubble, restoring power and water, paving projects, renovating schools, irrigation and agricultural projects ... all of these are contracts funded by State, often through US AID, but the contracts are managed by the combatant commanders as part of COIN operations. We spent millions in our local areas, processing hundreds of local contracts for things like desks in the local schools, and pavement. Also uniforms for local police, etc.
We did not privately buy an Army. Back to your own source, no offensive operations. The 1-3 ratio from Korea is apples to oranges because we did not use $ to stabilize Korea as we are in the present war. Its not enough to simply state # of contractors, you have to specify what they were used for, and this is a completely different operation.
I and most combatants agree that it is wrong to use money for leverage the way we have in this current war. That is the politics of this war, and I disagree with it. If I'm a political officer as you say then I am the worst one in the force.
