Supposedly, during WWII and before, the military had a problem: only about 50% of the guys with a gun in their hand, were shooting to kill the enemy. That is, about half of their troops felt morally bad about shooting at another human.
I think that it quite possible that a side effect of CoD et al, would be that those who played it who later did join the military, would have much less reluctance in shooting at others. Whether this is deliberate on the part of the military or just an unplanned outcome, I don't know.
If they go to the military and act as if it is CoD then the only one that will die are themselves. It is an interesting question though, however cheeky my replies may be.
