I’m not an expert on firearms, but “.410 caliber assault rifle”?
I’m guessing the “.45 caliber Thompson semi-automatic carbine” refers to the semi-auto version of a Thompson SMG, but I’ve never heard of a .410 rifle cartridge?
Well, be thankful they did not have the Birdman Weapons Systems Nuke 50. It has a computerized micronuclear 50 BMG projectile.
