You have crossed a clear red line in creating a topic dedicated to racism. This type of disrespectful, inflammatory speech is not tolerated on this site.
Let's try not to bash people when pointing out where they went wrong.
As for the beginning of the thread, I must say that your argument is not convincing. Use more details and proper reasoning to support your argument; it would go a long way in persuading us that USF "is trash in every mode."
Finally, I encourage you to try out the USF tech changes, which would resolve the issue of USF teching limiting Support Weapon options.
Lightning War is extremely strong, as is Jager Armor (but usually is more map-dependent).
I would add German Mechanized (Scopes + leFH + Command P4) just in case you need an easy way to counter SimCity. Alternatively, Spearhead (Mortar HT + Panzer Tactician + Recon + Tiger) is also quite decent if you encounter support weapon spam/SimCity.
Osttruppen is also quite viable, as it gives you decent early map presence and extra support weapons to really lock down the map. Osttruppen also become extremely cost-effective to hold territory when you tech to T4. Railway Arty can counter allied howitzers because the first shot is pinpoint accurate.
From my own experience (as I prefer skipping AEC and rush Centaurs) Centaurs are generally a defensive unit.
Play defensively with your Centaur, and use it to turn infantry engagements. Back it up with credible AT assets. Offensively, use it to support a large push.
Generally speaking, this is the standard operating procedure:
1. Do your best to remember if names pop up, and which ones pop up. They are quite helpful in dealing with possibly drophacks.
2. Upload the replay of the fishy game and name it "For Sturmpanther".
As this isn't exactly discussing strategy and tactics, and that I have told you how to resolve your issue, I am locking this thread.
