You blundered. All of those sources compare the M1 Carbine to the modern standards for assault rifles. The M1 Carbine is a WWII era weapon. It is not a modern weapon. It was designed prior to WWII.
Do you see your blunder? Let’s hope so.[/quote]
The definition is absolute and not time dependent! It’s not like the definition of a sports car (as you claimed earlier) - it is a defined entity, and the definition has not changed from the Stg.44 (which invented the term) to the present day. There is, as you have said, 1 pre-WW2 wpn that fits the description (Federov Avtomat), and then the MP43 in WW2, so your claim that there was nothing to compare it to is false. It is unique, and it fits in its own category, not in the category of assault rifles. If your claim was true, then the Mauser C96 with shoulder stock, the Artilliery Luger with shoulder stock and Bergmann MP18 (it’s rifled & fires hot 9mm Para loads) should be considered “assault rifles” in WW1 because of the way they were used!
If I blundered, then you are the only person in the whole wide world that didn’t, since you are the only person I know of who is claiming this! How come you are so “enlightened” as to think that you can go against all accepted wisdom?
If you back yourself up with some respected sources, then I will change my opinion, as will all the others here. If you can’t and are a gentleman, you should concede defeat. Over to you.
