I don’t think their anti-infantry capabilities should be used as a classification criterion
Because anti-infantry capability does not mean meeting class needs
What’s more, infantry is fully capable of counterattacking and avoiding these things.
1 Defense ability
Their armor is very weak
The 42 rocket car itself is just an armored car. Even anti-tank rifles can penetrate it.
The body of the T34 is only a level 3 Sherman and the rocket rack itself is an ammunition rack.
2 Attack ability
60-round M8 and 75MM cannons and 20-round large-caliber rockets sound powerful, right?
think differently
It is difficult for M8 rockets to penetrate 40MM (tiger top) armor
And almost all tanks of level 2 or above have equivalent frontal armor exceeding 50
The 75MM gun is of no use against the level 4 Panther
Large caliber rocket? Even Sherman’s armor is hard to penetrate, let alone he only has 20 rounds.
T34 should stay at level 3
42 rocket car should stay at level 2
should be new addition for BR4.
