That's certainly possible, but we've had a great deal of technological advancement between 1933 and now. Hell, the Nazi army used the kar98k as its service rifle - a bolt-action rifle. Body armor more or less didn't exist then, communication and transportation weren't all that advanced, and it wasn't until the tail end of the war before we started seeing tanks and other armor that were anything even vaguely similar to modern armor.
That's kind of the point everyone's trying to make. The bit about resisting tyranny may have made sense in the past, but technology has advanced to the point that rifles are probably not an effective deterrent to tyranny at this point. Maybe if private citizens were allowed to own LAWs and you could buy a Bradley at the local Cadillac dealership...

Sure, and at least you served so you can claim you followed up on those ideals. To the rest of those loudmouths that never served yet talk about fighting tyranny - go hop your ass onto a plane and go help those people fight ISIL out there. You want tyranny, there's your fuckin tyranny - now go help them shoot it.
I just don't see how a thousand angry rednecks with hunting rifles will amount to absolutely anything useful in terms of resisting a tyrannical government. They would almost certainly be branded as domestic terrorists and have public opinion against them.
