Ok here is an enemy with a gun, I could care less if he was a nazi with an 88 pointed at a sherman, an American with a thompson, or whatnot pointed at the protaganist of this tale as long as he has the ability to shoot you, it is A-OK to shoot him. Do you know how simple it is to operate an RPG or SA-7 or Stinger? Do you know how many time people with "mortal" wounds continued and killed? look up Baby Face Nelson. Its war, war sucks. if there is an enemy near a gun and he doesnt surrender then he needs to be killed. But if he surrenders then its a different story. and if you go against the rules of warfare then one needs to be punished.
