Some people have already mentioned it, but probably not in the most constructive way. The music is not right for your subject matter. A jolly tune, while killing people doesn't mix. Unless of course you were going for the irony, in which case, it went right over my head, lol. You don't necessarily need to have heavy metal (way too overdone) unless it is Tool of course, but something with a bit more oomph!
As for what footage was there, I personally did not have a problem with the tank and Apache kills. Your pilot is obviously good and so are you with your TV gunning and putting that in a video is not a problem, but I have to agree on the Blackhawk footage. Sort of like watching a professional football player pwning some school kids.
Editing was pretty OK. It makes it difficult to comment too much as the music was not right and when you get the right music, you may need to edit a little more to time some of the action to the music.
Overall though, about a 4 out of 10. For a first time effort, I will give you a 7 out of 10. I expect an improvement next week though or you may find yourself voted out of this competition
