That video is so fake.
Lets see, there's a planet of the Apes movie coming out from 20th century fox, and the video is from 20th Century Fox "research library". haha.
I've never seen African soldiers with such identical uniforms (or so unstarving looking), or with weapons in such good repair. Or a Steadicam. Also, the puffs of smoke have a distinctly CGI look (and I didn't see any brass). Last, my AK doesn't sound like that. That sounds more like a .30 Browning.
