You guys are forgetting that the USF player invests 120Muni for that LMG upgrade (by far the most expensive upgrade for any infantry). Since USF buys LMG, he/she is going to lack air support (which is critical late game). Not to mention the devastating effect to the USF player if he loses his Para LMG squad.
Investing large sums of muni on Elite squad for capable AI ability is not OP.
Everytime I read this argument, I laugh my ass off, you make it look like you have to keep paying 120munis every X time or something.So Once you upgrade your unit, you have to keep upgrading it because if you dont, then the unit wont have that upgrade anymore? Lol. If you lose a squad, then yes, because its your fault.
But if you dont lose any upgraded unit.. you can farm muni for your precious airstrikes..
