In other words you changing faction design in order to replace call in infantries with Penal, while makng the early play style of soviet similar to USF. The question still stands why? is the soviet faction under-performing?
Soviet do not need all their support weapons, even if they did building both T1 and T2 cost less fuel than a single USF and 1 officer gives less access to less cost efficient weapons...
You seem to be missing the point of weapon profiles. One is to have categories of weapons with similar behavior the other is to have range where one infatry has an advantage over the other.
A shock troops for instance is more expensive than gren yet it would badly if it fight a gren if they fight at range 35 while it win over an Ober who is more expensive if they fight close. What you are suggesting make gren volks lose at all ranges...In addition even PG and ST will lose far (around 45% less DPS and around 40% less HP)and will probably lose if they try to close in from 35 under fire or probably lose at all ranges if Penals have flamers...In other words axis will be forced to either spam HMG or go for vehicles.
You also seem to forget that the difference in DPS will become even worse for axis units at vet 3...Penal vet abilities and vet bonuses need to change...
Gren bleed far worse then Penals. By vet 2 Penal will be able to ourah to mid range and obliterare both gren and Volks.
Glad to see that you realize that you can't simply buff a unit massively and expect that everything will be fine...
Try rushing a Soviet sniper supported by Penal with the number you suggested...you might find harder than you think.
And once more why do object in giving Penal a bolt action rifle?
how is it breaking soviet to buff a useless pre-existing unit? how is it breaking soviet to make the soviet less dependent on a selected few doctrinal choice? it would change the current soviet meta, but that's different from breaking soviet design.
going both t1 and t2 also cost more manpower than going either lt or captain for the USF, and even more manpower if soviet actually intent to make use of the new units.
USF vs SOV is also ultimately irrelevant. the game is about Allies vs axis, not USF vs SOV. I'm using the USF rifleman as an guideline of what work, not as competition.
What really matter is How would the axis handle t1 + t2, and my answer is the fact that going t1 +t2 will delay the soviet light vehicle due to the amount of manpower required. The german 222 will especially punish a heavy t1+t2 building
actually the rifleman can match/beat the grenadier at long range, it's just not efficient. What give the wehr supremacy at long range is their support weapon, specifically their mg42. The volks is also a superior base unit compared to the grenadier, but the volks evolve into an anti-tank squad while the grenadier evolve into an anti-infantry squad.
A big enough price difference can also overcome the inherent advantage from weapon profile. A Panzerfusilier will flat out beat conscript regardless of range.
1 penal + 1 sniper vs 1 mg42 + 1 grenadier. the mg42 pin down the penal while the grenadier chase down the sniper. Honestly it wouldnt have been any different from conscript + sniper vs a grenadier + mg42.
