I wouldn't call it "pro-American." It was probably a bit "Amero-centric." Too much from the POV of US weapons.
They did mention Germany as the front-runners in MG tactics, though.
Ok, after watching the whole thing... what a load of crap. They did have some interesting stuff, but.
Mobsters were much more likely to use a shotgun or pistol, or even a rifle, than they were to use a Thompson. This is leftover FUD (fear, uncertainty, doubt) just the same as the new form of FUD is that all gang members use "assault rifles." And then they demonstrate nicely that the scariest weapon in the hands of someone who doesn't know how to use it is worthless, so which is it? Evil and scary, or just another tool?
The graphic of the 5.56 round shattering in a torso was more BS. Yes, they'll tumble. Yes, they'll sometimes fragment. NO, the fragments won't take such a dramatic path as the one you see winding up down by the figure's hips! This FUD about 5.56 and 7.62x39 tumbling and taking a right turn at Albuquerque and coming out someone's foot pisses me off. I STILL here idiots who claim one of these can "bounce around inside you" like a ball in a pinball machine. Idiots.
I'm throwing the BS flag on the Vickers bullet found in the tree. Rifle caliber will go straight through that tree. 9mm ball should go through that tree, or close to it. It's not a big enough tree to catch a rifle bullet.
Meh. All in all, not a terribly good video. They screw up on a lot of basic stuff.
