I could speculate on any number of reasons. A large number of my relatives work in defense contracting and you see the same videos passed around there as well. I admit that I feel slightly unnerved by the videos sometimes, but if you're an engineer working on gunships or a former soldier for whom this was a part of daily life for a while, I don't think there's anything really blameworthy in finding videos from the war interesting on some level.
