then hf fighting off IS2 and Churchills with it
It sounds like a really biased statement.
Raketenwerfer has a penetrating power of 200/190/180 and 160 damage.
There is only one churchill heavy tank except the callin unit, where there is a 1% probability that Raketenwerfer will not penetrate.
This obviously means that you can completely control the Allied medium tank.
This is much higher than the USF's 57mm AT gun penetration power of 150/140/130.
But think about m42.
It is clearly designed with light AT and has 140/110/90 penetrating power and 80 damage.
This is lower penetration than USF's Bazooka, and the same damage. With a penetration of 90, the probability of penetrating the stug-III is only 57%. And even that can only inflict 80 damage.
The m42 is apparently designed to stop the light-tank from the design, and that's why it has gained some anti-infantry capability.
However, Raketenwerfer has no shortage of anti-tank ability.
Imagine as you said, Raketenwerfer has Anti-heavy tank capability. this the right balance?
