They pretty much already are. That's why the defense budget is so high already. It's a money funnel to defense contractors. Almost every aspect of it is just paying contractors. The military doesn't do a lot outside of just supplying the cannon fodder. The only thing left to do is privatize actual soldiers. But still, there's be a capitalist needing to make money off them and soldiers are already paid next to nothing as it is.

So realistically, this move has me stumped.
