Thought I might chime in, INTJs make very good mid-high level commanders. We excel at the big picture, and understand that wars are not won with fancy technology or a few victories. Almost every single war is won through attrition. (Full War Mode)
The idea is to make as many of the bad guys die for their country, than your guys die for theirs.
It is also this reason nuclear weapons keep us in super power status, we can kill more of their people, than they can kill ours.
IF I was on the ground, I would be a long range sniper, Barrett .50 Cal please.
