I'm fairly experienced with the game (500 hours), but at least half of it I spent on campaign and Theatre of War. I decided to main USF and play it. After a while I learned more and more, untill I started dropping from my ranks (was at 6, now at 3). Frustrated at losing as UKF, I started playing OKW. To my surprise, I played OKW without any problems, and I have reached rank 8. I don't know why its happening, but maybe I'm just playing wrong, so I will list off my average match

I start by making 3 rifleman squads, (not echelon, I know they're worse) after a while I get enough fuel for a captain. Meanwhile, my 3 rifleman squads fight struggle with MG42s and Sturmpioneers (mostly them, but sometimes my rifleman struggle with other things). Sturmpioneers aren't as bad, but sometimes enemy overwhelmes me with them. But the worst part is MG42s. I try to flank them, but the enemy also attacks me with Granadiers or Volks, meaning I have no manpower for defending and flanking. After this engegement, I reatreat, leaving my enemy to make defences. For some reason, I dont have enough ammunitions for anything ( even though I didnt spend much, leaving me with no Browning (doesn't make sense to make mines), but I have enough fuel, so I buy AA gun to help my already weakened infantry. Then I lose it to some armour dive, beacause they have more fuel than me. I lose and lose more man, so I get a Major, then, a Sherman. It really helps with those elite units. But then enemy brings in P4 or Panther, and we know P4 or Panther > Sherman. I get more shermans, but then more tanks come in, including king Tigers. Frustrated, that the tiger always attacks, kills a bunch of stuff, and then leave makes me frustrated, making me dive the tiger(my bad) .Then I gradually lose everything to infantry and tanks( sometimes artillery) and then lose. Also my commanders are the Airbourne one, ranger- calliope, and Pershing doctrine. I hope it was specific
