This is what Bill O’Reilly has been proposing, and Prince agrees. Every nation wanting protection would help pay.
Except that O'Reilly wants only an international force with no Americans in direct combat and Prince wants a 100% American merc force.
There is a problem with this proposal and maybe I see it because I'm looking at it from the point of view of an Infantry Captain. The former Blackwater corporation and other PMC contractors are mostly drawing their employees from the ranks of special operations and those guys are literally the GOLD STANDARD of operator.
Rangers and Marines are also in the mix and those individuals are classified under the category of "super infantry." and they understand the nuts and bolts of that job. They can work under the active umbrella of mechanized warfare in the case of the marines. They can work under the active umbrella of artillery or mortars and they can maneuver with armor.
They don't do the prowl and growl of special operations who perform nighttime HALO insertions from 35K feet up and free fall to 1000 feet OR "hop & pop" at 35,000 feet and open the chute immediately to glide under open canopy up to 24 miles for a silent pinpoint insertion by an extremely small group for a very specialized mission.
The problem with giving these guys orders to conduct full scale infantry attacks is that they're not skilled at huge operations with hundreds of men. The Rangers and Marines are but they represent a fraction of the employees of the PMCs. If you wanted to let these elite men loose as a distinct force multiplier for a much larger group that would be fine. Sniper teams for example. But these specialized folks don't take and hold ground. They are surgeons who remove specific cancers from existence. Using special forces as standard light infantry is a huge waste of resources. And they don't do that very well, either.
