Fuck robots.
I have the solution to our defense needs. Just use inmates. Think about it, they could be minesweepers, human walls in front of the real troops, they could be the bloodhounds to go into fox holes and get insurgents out, decoys, the first ones to bust into houses/buildings, etc... Just give them a sling shot and a couple of rocks.. If one wants to run away in the desert then let them..who cares.

It'll also solve the prison overcrowding and could drastically reduce the defense budget.
