This AT gun is currently way too cheap and very cost-efficient, resulting in an overwhelming performance compared to any other AT gun from the game. Costing a mere 270MP and being able to recruit it from your initial HQ is just too out of sync with any other factions that are having to struggle recruiting expensive 320MP AT-guns with worst performances.
Allies AT guns are far more expensive but have worst performance, so why would that be? Enemy armor ** and **low chances to penetrate it
Even if the Raketenwerfer has "slightly weaker" stats, it comes out on top in performance, simply because Allies medium tanks have less armor but most importantly far fewer chances of bouncing enemy AT bullets. Resulting in squishy Allied tanks getting demolished by the cheapest AT in the game.
Just as a reminder: The Raketenwerfer 43 Anti-Tank has a faster rate of fire, movement speed, and rotation speed, not to mention that it already comes with camouflage unlocked, instead of getting it at Vet1. Additionally to that, this AT can penetrate around 90% of times against Allied medium tanks (extremely unbalanced stats for such a cheap T0 unit)
The mix of the variables mentioned before allows this faction to be the only one sending AT-guns without bodyguards to simply chase down and annihilate enemy vehicles, as they also come with an easy quality of movement speed and Retreat option. This unit simply has a lot of abilities to offer for its very low cost.
Having high penetration values and a low cost allows this AT-gun to be the most overwhelming AT-gun from the game! ironically it has a 43mm gun to deal damage, but it can heavily outperformance the 45mm AT-gun from the Soviets and of course any other 76mm AT-gun.
Another observation is that the Raketenwerfer 43 is supposed to use the fearsome Panzerschreck to deal damage, as the unit description is written. Proving once again if that is the case, of how bad the Panzerschrecks are balanced.
