Would this be so much different from what it does allready? Besides, killing one model at 5 seconds would be nasty for grenadiers, so-so for volkgrenadiers and rifles, and not such a big deal for soviets. Model numbers in a squad it's not counted among soviet weaknesses ya know.
Considering it needs 20 seconds of shooting while stationary at max range at no cover pio?
Answer it yourself.
Also answer yourself how would the bigger squad count matter if you got 2 of them.
I'd love to see 222 and M20 getting long range DPS buffs, so they are actually a threat, but 222 in coh1 was deemed fragile, but with overpowered DPS. And as an avid user of them back then, yea, it would be absolutely horrible to have something like that in coh2. Middle ground between that and current coh2 222 would be sufficient.
