No individual unit are balanced around a benchmark unit.
They're not.
You might think they
should be, but you only need to look at the 450 MP Infantry Section in CoH 1 or the equally priced MG42 and Maxim in CoH 2 to see that's not how Relic thinks.
They don't price Riflemen based on Grenadiers, because you never have a choice between building Riflemen and building Grenadiers: they're in different factions. Riflemen are priced against .50 cals and Rear Echelons.
Same with Soviet: the Maxim is priced against Conscripts, Penal Troops, Snipers, Mortars. Not against the HMG42.
The M10 Wolverine isn't competing with the StuG or the JPIV, it's competing with the Jackson. It's never been a bad unit, but it got buffed up to its current level because it has to compete for fuel with the M36.
The Vickers didn't get a price drop a few patches ago because it was weaker than the MG42, it got a price drop to make it more competitive against the Infantry Section.
When balancing factions against
each other, you look at the entire army and its dominant strategies. Nothing exists in isolation.
