First off, the USF Commander is only used for the RE Rifle Grenade spam like it was already predicated, I have literally not even seen the Sherman Bulldozers being used, or the Calliope for that matter.
2nd off, where exactly was your suggestion for the British Commanders? The topic about the UKF suggestions were the least replied to or viewed and I don't remember your suggestion or comments so shitting on the idea is solely your own opinion and no one else's.
And lastly, there is no bug for the 251, it's a feature that just needs balancing, and the OKW Commander, much like the USF one, is only currently being used to spam Panzerfusiliers armed with double shrecks and nothing else, the Tiger while not useless I see a lot of people just suicide charging and leaving to die so they can get a KT instead since it's a weird Commander-but-not-exactly type of unit and you're asking yourself why not just get a KT or have it reworked to be a proper Commander unit or replaced by a Tiger Ace or a Command Panther or anything else really.
251 half-track can be retreat point now
that is bug
smoke+sprint is OP and buldozer+ white phosphorus destroy all AT guns
only used for the RE Rifle Grenade spam??
What is your rank?
