My idea is that the military should fund itself(or at least partly). They would do this by obtaining a lease or temporary rights to natural resources in places they are deployed. Obviously there would need to be some kind of oversight. We can’t have the military deploying itself to all the resource rich places in the world just to cash in. But it seems to me when America is doing police type actions all over the place, someone else should be helping to pay for that. We could do something like this: Allow the military to seek out it’s own funding to equal the value of the fuel and ordnance consumed, but no more. And they would not be allowed to take resources from region A to compensate for expenditures in region B. So would they take if not granted rights to resources, kind of like the armies of the past used to do? Just take whatever the army needs, even if they don't have any rights to it?
What you are referring to is room and board, I think. That is what militaries did in the past. That’s hardly a need of american military. Today’s military needs fuel and ammo. How many private citizens own raw materials to produce fuel and ammo? No, private citizens would not suffer from my idea.
