Without even trying to find the video, I'm guessing this is some bullshit about the army's jungle warfare school in Hawaii, which trains like 2 dozen soldiers at a time to do shit like tying knots, rappelling, orienteering, and other basic outdoors shit but in a rain forest environment. So, this is supposed to be an indicator of how the army is training for war for China? Like bruh, this is fucking boy scout summer camp but for marginally grown-ass adults
