Blackwater is an American owned security company working on contract for the United States. That doesn’t quite fit the definition of a mercenary. There are civilian security contractors on every US military base in the United States because the military was downsized to the point that it can’t spare the people for those jobs just as it doesn’t have enoough to do those jobs in Iraq. Get the active strentgh back to what it was pre- Desert Storm and we can let the contractors go...
And this is my point. The REMF stuff is fine (and smart to an extent) to contract out. But these are security. The military should be able to do that in house.
