Ciez, i agree with most of your points, but not about the stuart, it's good against infantry, but not that amazing against anything else. I haven't had too many stuart vs flak HT fights, so i'll give you that one, even if i remember it not being that awesome or one sided.
However pumas deats stuarts handily afaik, unless the ability for critical completely turn things around.
Stuart has little health and armor in my experience, i've found that m20 tends to live longer thanks to smoke and maybe smaller size making it harder to hit. but both go down in 2 hits from a decent anti tank weapon.
About rear echelon, the volley does need to take in account cover more, imo it shouldn't suppress ennemies in green cover, but maybe should suppress faster than atm in negative one.
But overall i find lethality to be a significantly too high on both side, sometimes unit just evaporate in 2 secs with the player being powerless against it.
obersoldaten lmg and maybe a mass of lmgs or bar tends to liquefy units too fast, even in green cover.
Late game, rear echalon have to hide.
I'd also like to point out it's hard to get rid of a forward truck without an AA ht. zookas just take ages, at guns work fairly well but are very vulnerable and slow, so it depends on terrain.
