Speaking of deer-overkill, a female friend of mine had her 21st birthday party this weekend, and her butter-bar (2nd Lt, M1A2 tank commander) boyfriend drove up from Fort Knox to attend the party. He brought along his laptop to show all the guys (and non-enviro-weenie girls) a really funny video.
During night exercises, the tankers use thermal sights to find their targets, well, at long range the heated part of the target is about the size of a deer. So, during the video there's a moving target going along, the gunner's tracking it with the main gun, and he pulls the trigger right as the target crosses between a deer standing on the range and the tank. (The deer on the base are notoriously stupid and will hang out right in the middle of live fire exercises)
He missed the target (it went over the top), but SPLATTERED the deer all over the place, you could see the giblets flying up in the air on the thermal scope.
The next day, the crew went out to where the target was, and then started looking behind it for the deer. All they found were four legs just sitting on the ground.
Now THAT proves the only 100% sure kill on a deer is a 120mm Sabot.
