Literally put troops in front of your tank and watch volks waste there volley on infantry and move in with tanks. Or imagine they ignore your troops so they can fire at the tank. Solution? Backpeddle with the tank while your troops shoot away.
I love the USF AT gun, at vet 3 it's amazing and has HUGE range.
You get rewarded alot if you manage to keep it alive, like with the jackson, it's amazing when vet 3.
Your suggestion would actually nerf the sherman imo, the smoke ability is amazing for supporting your infantry.
Your sherman is like a giant support weapon, it's not like a comet which is meant to push through the lines by force. The sherman is only for flanking heavies, or moving togheter with rifles to keep the opponents elite infantry at bay and at a certain degree sponge damage.
USF is perfect right now, the pak howie needs nerfing and the mechanized doc half track needs a health increase.
