I dont think reducing initial cost is a good idea. That would require further balancing to keep riflemen spam at bay. Beside usf has already pretty good start versus ostheer so it would be bad for that matchup.
The problem in usf vs okw matchup is you bleed MP so heavily, there is high chance you will end up with your squads near ambulance, waiting for your MP to refill for reinforcing. It also doesnt help that rifles are slow to vet and they get at nade at vet1 instead of useful combat bonuses. Also, volks are getting stronger much sooner than rifles. Their weapon upgrade is easier to get and they get combat bonuses starting from vet1.
In my opinion dropping reinforcement cost to 26mp and moving part of vet2 and vet3 bonuses to vet1 (alongside at nades) would be best solution. Also dropping MP cost of ambulance to 100MP would be good too.
