222 has 2 weapons and he posted ONLY the coax.
Autocannon have 40 penetration and 20 dmg per shot
He just gave the raw values without incliding them in DPS, so here is the DPS:
[...]
222:
8,3 FAR
24 CLOSE
So, as you can see, not only 222 is one of the cheapest, its also hands down most powerful one and is able to fight independent of other squads thanks to turret. It also has enough AT to reliably damage and in numbers of at least 2 even KILL light tanks.
And you simply ignored the fact that the 222's MG is completely broken, and basically doesn't fire 99% of the time. The real DPS of the 222 is 1.77 (far) and 4.02 (close) because of that. So yes, it can engage enemy light tanks with ambiguous outcome (unless you appear with numerical superiority), but against infantry even a T-70 will be more effective in any situation, simply because it will actually hit and when it hits it will deal more damage.
By the way, it is pretty dishonest to include a doctrinal unit for one faction, and non-docs for the others, making it seem like one faction doesn't have a comparable option. The M20 in its infantry-support role deals more damage than any of those units, except for the 222 if the coaxial MG would be working correctly...
P.S.: That said, the Dodge could with some change, if only to make it more interesting. Right now the idea of a firing platform doesn't seem that novel, when the Russians had that since the launch of the game. Before anyone cries for buffs though, keep in mind that the 250 halftrack (the short one, that can only take one squad) is even worse off. It costs even more and doesn't deal any damage at all. It is basically worse in every aspect than the Dodge (a feat in and of itself), and yet nobody gives a damn.
