Embedded With Special Forces in Afghanistan | Part 2

In this video, at 7:30, and 9:44.

The background music is so awesome, but no matter what I do, I can't seem the find the original source of the music. I'm beginning to suspect this is their exclusive self-made music, but does anyone has any leads? Please!

If there is no way of finding it, can anyone introduce me some similar songs or music like this? Thanks a lot
