@squippy, sorry for putting words in your mouth. What I meant was, defensive bonuses are better than nothing, but they were completely nonsensical on stuff like mortars and AT guns, essentially the coh1 implementation of global veterancy was flawed from the beginning and even if offensive bonuses were given. It ensured the bonuses would have to be poorer than the "earned" veterancy because of potential for late game spam of elite troops. Some might consider lategame fielding of elites only a cool defining faction perk, just like OKW forward bases and fuel penalty, but I simply think it is not possible to balance it alongside other factions that gain veterancy the "normal" way.
Fair enough. And in the interests of raising the tone of debate, let me say that I did read your more detailed argument, and while I think I ultimately still disagree with you, it's always much better to end up disagreeing over detailed well argued positions.
Although I will say, everyone has a moment where you're praying for that last PAK shot that will kill that tank marauding in your base, and which if you don't get will mean the tank kills your gunners and then everything else you have. Defensive resilience has its virtues.

Also, IIRC, one of Coh1's Wehr vet levels gave passive healing, so again they were a lot more survivable. And as ZombiFrancis mentions, you could always use the 5-man Volks squad to absorb fire before it arrived on your 4-man grens.
On top of this, the basic infantry units had different health values:
Rifleman: 55 health
Engineer: 55
Volksgren: 60
Pioneer: 70
Grenadier: 80
Tommies: 60
PE grens: 55
So a gren squad had a total heal of 320 and a rifleman squad had a total health of 330. But the difference in per model health meant that individual grens were more likely to survive a grenade that would kill most of the models in a rifleman squad. In both cases, the squad itself could well avoid being wiped.
EDIT:
According to the chart in the OP, CoH2 Grens, Conscripts, and Rifles all have 80. So in the respect the relationship that existed in CoH1 where Wehr models were tougher is gone, but the proportional squad sizes remain.
