I think you are talking about the personal security industry (Blackwater et al). Think there are probably more opportunities for MBA types in LOGCAP (Logistics Civilian Augmentee Program) areas. Kellogg Brown and Root, DynCorp, and Fluor are the big three in country right now and will probably stay there for a while. If you do have any interest in working abroad (specifically Iraq/Afghanistan) in this capacity, you would probably be working as a Program Manager of some sort. Generally speaking though, you need to have some sort of military background (logistics a plus).
