And my B-4 fires twice, now no PAK-43 and no Medtruck.
I think the Pak-43 can be a good way to fight, under a few specific scenarios. Only if does soviets industry and towards heavy T-3. Any T-4, off-map or on-map artillery and all forms of static defences will melt away with little effort.
thats assuming they go counterattack doc in the first place. one shell cannot hit both the pak and the truck, so your sturms can just repair which ever was hit inbetween barrages. sturms have the highest repair rate in the game, and have an even higher repair rate with the minesweeper upgrade.
katyushas actually have horrible accuracy, and even if you start losing models u can just reinforce since its next to the medic truck. also you should get a stuka most games, it helps to deal with enemy weapon teams and b4s too.
