My reasoning is as follows,
If we take a look at all the other nations auto rifles, you’ll notice all of them do significantly higher damage than the M2C.
The Japanese Hei Automatic rifle Un upgraded will most likely do the same as a regular Hei at 11.6 damage and when fully upgraded with the 20% damage boost will do 13.92 damage.
The Russian AVT 40 when Un upgraded does 12.7 damage and 15.24 when fully maxed out.
The German FG-42 and FG-42 II both do 12 damage un-upgraded and 14.4 maxed.
Now the M2 Carbine does the lowest damage by far out of all of these at 7.3 damage when Un Upgraded and 8.8 when given max upgrades, that’s about the same damage as any other assaulter weapon hence why I believe it should be replaced by a t20e1 or e2 which can do similar damage to the other auto rifles in game.
America really needs
In the future, all three camps may have full-power automatic weapons
The United States is still using the highly stable and low-damage M2
I still think it’s a carbine rifle, and at worst a PDW, which makes it a Rifleman’s weapon. But, what do I know. Not like it’s literally the same dang thing as an M1 but with a piece removed/modified
