i said tier 1 not full unlock and u can see i counted it in the advantage of okw
Fair enough, although it's more comparable if we go for full onlocks on both tiers. The USF split was done for the sole reason that USF is not locked out of MG and AT gun for the late game by high pricing.
Also for the advantage list: It's not much use for USF to get the side techs before their first tier, since first you need the officer to even out the infantry numbers (building a fourth Rifle early is usually not a good idea and rarely done as you will have too much infantry and bleed for mid and late game) and you first need to get the mun for weapon upgrades (which both factions usually do not have before the 5 min mark).
Also if should be noted that USF does not have smoke and nade on a single squad which was patched out for good reasons some time ago. They pay for the mobility of their ambulance by constant pop cap use and high fragility of the unit, even in early game.
OKW also has standard snares on every unit (Riflemen can sometimes be snare-less before the first LV hits the field, although this is not a huge problem when dealing with the Flak half track, only with more aggressive vehicles). OKW has the snare problem against USF only in the doctrinal dodge car.
Also OKW gets 4 units unlocked with the first HQ, as they can also build the MG from the main base. And they have the incendiary from the very start, so saying that USF could get the upgrades earlier than OKW is a bit far fetched.
If USF would research the nade at the very beginning (something that OKW gets, and the nade is not straight up better than the incendiary), this would nullify the start fuel disparity and increase the early MP disparity at the disadvantage of USF. Both Tier 1 would then come at about the same time, USF could get the medic slightly earlier (at the cost of more MP) and get the weapon upgrade again slightly later as OKW (plus more MP).
