More of a specialized weapon though. Not a general use field rifle.
Yes, as a part of a squad it could prove invaluable.
I wish it had a larger magazine, though...
We still issue the M203 with infantry squads, the M-79 is making a comeback and the USMC has a rotary 40mm launcher.
I think it has definite possibility as a dedicated, general-purpose weapon.
However, when it was part of the OICW, it had a 5.56mm rifle in the equation. I wouldn’t want to be an infantry man without a rifle. I suspect they’ll also carry a carbine.
