Mercenaries the future of warfare?

[FM WarB]

KBR is feeding our troops in Iraq. Contractors' performance has not been exactly stellar in Iraq. I too had disdain for Remfs during my army time, but I need confincing that those soldiers (such as they were) were more expensive than KBR contractors.

The Blackwater security boys cost alot, not only money, but goodwill of the locals.
I may be defining mercenaries a bit more broadly than the intention of the thread starter, but I think its relevant.
