I love grunts.
LOL@ the famous knife hand around the 2minute and 2:40 range to his SAW gunners. Looks like some grunts tired of lugging around AT-4's so they're ditching them. They're "fire and forget" weapons so they don't have to carry the empty tubes back with them. Max effective range is rated at 400m AKA once you've been carrying them around that long, why not take a good 600-1000meter shot? I'm only mad the squad leader did it rather than letting another one of his guys do it.
A bunch of us are mad we missed out on the helmet cam era of the war
