They do that now to civilian contractors with guns, road blocks and IED's. At least this way only the truck and the gear is at risk, not innocent drivers or non-combatants. But I do agree... a computer will never replace a human mind. Being able to see whats going on and make decisions. I would have them remotely driven or at the very least monitored just like with a lot of the drones. So at least there is a real human mind in the decision making process!
