And if USF decide to turtle with fighting positions (LT?)/captain, howitzer and/MHTT how is Ostheer going to push?
Smoke and flank.
These two don't jive with each other.
But switching the AAHT and the Stuart just serves to reverse the very goals you're purportedly seeking. It'll always be LT first, with a decision to rush a stuart or go for an ATG.
Captain would become more a teamgame tier and lieutenant 1vs1 tier. On teamgame you can rely on your parnter HMG and you focus atg and pak.
