Spam of panzergrenadier's covered my heavy MG make USF infanitry useless,
What do you consider "spam"? Because a unit that costs as much as PzGrens is about as useful to spam as dropping resources into the enemy's base - in other words, it doesn't happen. On top of that, these units are only effective at relatively close ranges, so if they manage to get your MGs, you must have done something terribly wrong (probably got outmanoeuvred).
tanks (also Shermans) too weak VS Panzer4 covered by panzergrenadier spam with shreks
The Sherman is significantly cheaper than the Panzer IV, and performs on the same level, if not slightly above. It requires a tiny bit more micro, to switch between HE and AP shells, but using either in their respective category allows the Sherman to easily outmatch any vehicle of its class except the Cromwell. On top of that, your Sherman suffers significantly less movement penalties than the Panzer IV, so use that to stay mobile.
If the combination of Panzer IV and PzGrens gives you trouble, do the same thing: Use combined arms! Set your Sherman to HE shells and cover it with an AT gun, or set it to AP shells and cover it with your Riflemen or an MG. There are so many options available, unless you do nothing but right clicking your units into the enemy.
Hello,
cheap sturmgrenadiers and cheap Tiger (not cheap, but too easy reachable in late game) with massive area damage and garrison damage make USF useless 1 vs 1, becouse Wermacht player can keep only few (in my happening, 3) points (not fuel and munition!!!) and win 1 vs 1 game easy.
Do you mean Assault Grens? There are no Sturm Grens in the game, so I'm assuming you mean Assault Grens. They are a massively overpriced unit for their performance. They don't deal any damage unless sitting on top of the enemy, and their larger squad size is offset by their weak defensive bonuses and their need to constantly move across open ground to be effective. If Assault Grens give you trouble, you are clearly lacking any ability to micro your unit. And no, I don't mean to insult you or be mean, but calling Assault Grens problematic is bollocks.
Regarding the Tiger, it is less easy to reach than the Pershing. Your Jacksons outrange it, so use your infantry to spot for them. Don't push too deep with them, they are vulnerable to enemy tanks - they are a surgical tool, not a sword.
The Pershing again is a valid option against the Tiger, although you should keep the lower health pool in mind (the Pershing is like a Panther with better Tiger stats - it is not meant to take the same beating as the Tiger, but it sure as hell dishes out a lot more hurt). Again, all your USF tanks have severely reduced movement penalties, so keep them moving.
