Not sure I understand your post. In the version of COH2 that I play, the OKW AT gun is Tier 0, flame nades and panzerfausts are free with any completed truck and the MG34 is available after any truck is converted - making their cost for the unlocking team weapons and tech among the cheapest and fastest.
and in the version I play the USF mortar is tier 0, officer cone for free, panzerfaust come after set up and cal 50 come just after 35 fu unlike the mg 34 55 fuel (soon to be 50)
To put I simply, u are comparing osther and Soviet tech to USF , when we know it’s an unique tech structure like okw with branching choices, so u cherry pick what u like and what u don’t , btw last time I checked 15 + 40 + 20 is 75 not 70 , and I don’t see smoke nade or double lmg on any green or pgren
To put it even simpler u want the best of each faction in 1 faction with no draw backs , so u want both cakes
