Were you floating fuel? Did you check his fuel income? I mean getting the fuelpoint doesn't mean starving him from it.
Yes, I had more fuel to spend but point is I did not have enough MP.
Vehicles have higher upkeep than inf, right? OKW can rely only on inf in fact.
I need some vehicles to counter that inf, for example:
2x Raketen, 2x MG, 1x Stormpios, 4x Volks with schrecks, 2x Obers = 208 MP income
Major, Lieutenant, 3x Rifles with LMG or Zooks, 1xRE, 1xMG, 1x Jackson, 1x Priest, 1x Ambulance, 1x M20 = 187 MP income.
It's 11 vs 11 but pop cap is 76 for USF and 62 for OKW!
These are really big differences.
OKW always has MP advantage so when OKW has enough fuel, it can easily spend it.
As any other faction you fuel to spend but you are missing MP all the time.
Also vetted Volks or Obers models are really hard to kill because of recived acc bonus so it helps to collect man power.
