Updates in light of Ukraine war

[jp10]

I have noticed that few of the destroyed Russian armor seemed to be trying to use the terrain in a hull-down position. I believe the game does do Hull-down calculations based on adjoining hex terrain and a % but it is shot by shot, not a long term bonus like being in an emplacement.
Russian tanks because of their low profile and auto loaders do not as easily hull-down. Perhaps one take-away from the current news is this ability should not be allowed for those post T-55 era tanks built like that. (T-55/62/64/72/80...etc).
Also as each shot is displayed could a color/symbol/text indicate if a non-penetration was due to a hull-down advantage?
