Full Battle Rattle is a documentary that provides a glimpse into what war simulations are all about: bombs going off, people shooting at you, dead bodies piled everywhere. The only difference is that none of it is real. Everyone in this mock war is training for real war, but that doesn’t mean that anyone takes what’s going on terribly seriously. When people are using fake blood and the corpses talk back to you, well, things can get pretty weird. Check out the trailer after the jump.
