i hope it is two that weapon was pro

I hope it is.
That was my favorite gun in WaW

more than likely not. the m1a1 was barely used in ww2, the gun never saw much action due to its imperfections. and to the people that are calling him or are gunna call him stupid and flame saying "THIS ISNT WWII NOOB" you would be wrong, the game is vietnam based and in the vietnam war they used many guns that were used in ww2 including the thompson, m1 garand, bar, even the good ol' m3 grease gun saw some action. the reason is because funding wasnt great for the was so they had to make do with what they had, although it was a time when many of the weapons that are famous today were introduced. I dare somebody to argue with me about this

The M1A1 Carbine was "obsolete" after WW2. It was used very little in Korea. By the time Vietnam came around it was replaced by an update version called the M2.

All in all, the M1 and the M2 are the same. Just minor tweaks.

So it is very possible that it will be in the game. Especially since it is called "black ops" because the M2 was used specifically by Special forces or recon teams.
