I voted M1 Carbine, but isn't the M1A the same gun? And you forgot the M14.
M1 Carbine and M1A are not the same. The M1A is the civilian version of the M14, both chambered in .308. I think the only difference is that the M1A doesn't have selective fire. The M1 Carbine is chambered for the puny .30 Carbine. It's a neat little rifle. I've got one, as well as an M1A. I certainly wouldn't vote for the carbine as the best military weapon of all time.
