So, that is not a problem for you, that 1 T0 unit can fight effectivly against both infantry and light vechicles? For me it is too much for only 1 T0 unit.
No, cause it is not effectivly vs light tanks, only vs light vehicles like m3, m5 or bren carrier. M3 and bren are only effective in early game, where the mg will not have vet1 yet.
ZiS-3 is too slow and innacurate against light and speedy cars/tanks
Allies have speedy cars/tanks too, to flank the mg of doom. Waiting with a t70 infront of vet1 mg would be the same, as waiting with a Luchs infront of a Zis. Just drive behind hit.
Lose 70 fuel with T-70 or 60 with AEC/M15 AA platform to 1 HMG and its ability for 30 muni? No, thanks.
This will not happen, if you are careful. See a vet1 mg42: Hm, he could use ap rounds. Either drive behind it, or drive back, when it is in a house which is unflankable. Wait some seconds, and come again.
And Axis can spam freely cheap 222 or Luchses.
Freely...
222 are still worse vs infantry, they only live a bit longer as before last patch.
