Without actually seeing the video, it is hard to make a detirmination as to why he would do such a thing. I'm not trying to justify his actions, because it sounds like he was CLEARLY in the wrong and should be left outside for a while during an attack.

HOWEVER......I would need to see the whole video in order to make a decision. It is often easy to make a knee jerk reaction and condemn the guy to hell, but not know the specifics, and then later find out that the puppy had a gunshot wound and would not have survived anyway or some other thing. Get the video, and let us see it in it's entirety. then we can make a decision on it.

If the militayr member is doing something wrong, then he should be punished to the fullest extent of the UCMJ (Unifor Code of Military Justice).
