as far as luvnest said ostruppen shut down Soviet and mechanzied shuts down OKW
UKF is a gamble against sniper
so peaple are left with ost and usf.
Ost has 2 main choices in 1vs1 5 men grens and osttruppen. The problem is that grens bleed to much in the earlygame vs wc51. So your stuck with ostruppen.
All USF commanders without wc51 lack the early game to deal with osttruppen, plus mechanized offers the m4c in the lategame which is arguably better than the p4 (in AT at least).
So basically the problems come from Osttruppen being to good early shutting down the game in 4 min (FHT or PG) if your not carefull and the WC51 overperforming against OKW and expensive to refresh grens (WC51 50 cal has arguable too much range , and can escape 222 with step on it pretty easily)
*Uneducated suggestion alert*
- Reduce Ostruppen to 5 man
Then completely rework the WC51 because a utility truck being an aggressive front line unit is just silly.
- Make WC51 non-doc & put in battalion CP.
- Move forward retreat deploy ability from Major to WC51. Also add weapon racks when deployed for forward equipping (like forward assembly)
- Remove .50cal upgrade
- When garrisoned by an officer squad, WC51 gains the mark target and artillery barrage abilities.
USF can deploy it as a forward retreat and still use the Major aggressively. Also increases the penalty to USF for having forward retreat destroyed because it costs fuel not just a 3 man squad. USF now have a non-doc infantry transport for those off-meta games.
If that doesn't sound like a good alternative use, just yeet it out the commander anyway. Mechanized will still be viable without it.
