While extra track links and palm logs and sandbags did add some expedient armor protection, for the most part it wasn't going to stop a 75mm or 88m round from disassembling a tank. As long as it takes multiple hits in-game from a 75mm or 17lber. to kill a WW, or Sherman, all this does is convolute the issue. I posted this up a long time ago...and I'll do it again...this is what happens to Shermans and Panzers and T-34s when they're hit. If we're to go on the premise of semi-historical accuracy versus balanced gameplay, then it doesn't make much sense.

75mm round on the side of a Stug III. Perfect example of one-shot, one kill.

Panzer IV - or what's left of it. The caption says it was killed by a 45mm ATG.

I agree we need more tanks - I'd love to see a low-profile Jagdpanzer IV/L70, a Hetzer, Stug III, non-perked Sherman (M4A2 early for example). If you want an up-armored Sherman, look at the M4A3E2. We're still lacking a Panther, Jagdpanther, King Tiger, JS-1, JS-2, the entire KV-series of tanks, Su-85, 100, 122, and JSU-152. Then you add in the MW and EW Panzer III and IVs, Matildas, Crusaders, Lee/Grant, etc...
But...who's absolutely dying for a Semovente??? Italian or Japanese tanks? What about Humbers, or Staghounds, or 8-rads?
I think the key is to ensure balance. King Tiger vs. JS-2, both highly perked, both able to dominate the battlefield in most cases. Jagdpanzer IV L/70...spawn camping under some trees? Damn near impossible to see, much less hit. Same with Su-85 and Su-100. Rolling into a base take with JSU-152s?? Wow.
I think for the sake of gameplay, it takes several rounds or a lucky one-shot to kill a tank. No M8 driver is going to run around shooting at Tigers or Panzer IVs, he's going to get the hell outta Dodge. If we want to add in expedient armor, then GVs need to die like real GVs did in order for it to make a difference... in order to do that, we need more GVs types to balance things out even further, or to increase the probability of running into a GV that you can go nose-to-nose with in a fight.
Donning my Kevlar and heading for the bunker now...flame away.
