This. Falls are not supposed to beat Shocks 1 on 1 (nor any squad for that matter), but they can do significant damage against them if you've got them backed up, pop Valiant Assault or just retreat once the Shocks come close.
I don't agree with this either. Why should shocks win hands down exactly? Shock investment is 100% in the manpower and they come with their PPSHs. If falls through the mod go through, they'd have to buy the 2nd FG42s and come at the same CP for only 40MP(?) less? I don't see why 40MP(?) should guarantee a shock victory, especially if falls have to buy their upgrades. It's like saying why don't volks beat 2x BAR rifles. Probably because rifles have greater investment in their weapons.
If shocks should hands down win frontally charging an all range squad, Pgrens should be charging sections through open cover and rolling them.
