I want to discuss about damage of HE shells (basically medium (75-76-mm) and large (88-90-128) calibers).
At strat I show several examples in my past games:
Spoiler: show
I divide light-armored (i adduces only front armor) vehicles on:
a) "soft" vehicles with armor <20-mm : all types of HTs, scout cars, M18 Hellcat, M8 Greyhound, M20 Command car, Nashorn, Marder I/III, Gepard, Tetrarch, Bren Carrier, Daimler Armored Car...
b) very light-armor vehicles with armor 20...30-mm : some heavy recon cars (Pumas, Staghound), Chaffee, Mobelwagen & Wirbel/Ost-wind (good hull, but weak turret)...
I sure, that medium and large HE-shells must to make more damage against this soft vehicles (majority of soft vehicles have open cabin).
For example, medium HE-shells require 1, rarely 2 hits against "soft" and 2, rarely 3 hits against "very light-armor" vehicles; large HE-shells reguire 1 hit against "soft" and 1, rarely 2 hits against "very light-armor" vehicles.
Thanks for attention!
