Why yes, yes there is. It's called The Scale of Snafubar. We page Snaf everytime we're about to drop a bomb or something. He replies with an animated image of himself. If he's smiling, we're G2G. If he's stone faced, abort-abort.
(so, no, there isn't a scale that I know of)
I was referring to "shooting to kill" (almost sarasticlly) the enemy so that they're taken down the first time. If you fail to take them down, you're then also using medical resources in order to aid a wonded soldiers instead of just bullets. Also, it's illegal to attack red cross labeled transports.
In an unbounded war maybe. However, the US military is bounded by GC, UCMJ and the Theater's RoE. This isn't a free-for-all game. Your tactics are goverened. Our military isn't based on Guerilla Warfare.
e: Also, I think it's rather bullshit that they diverted the medical attention of those children to a lower-quality local hospital. We as a military have to face our action's consequences. If go in and destroy cities to only rebuild them, yet when he damage the lives of those cities we don't use our same resources to aid them. We fired upon a van which had no sign of returning fire. Instead if was acting as an aid litter, picking up wounded. Cheap.
