Short Friday Fun video grabbed by Reto.Blitz showing some of his debugging work on the new Vehicle Gameplay Update. Here an unfortunate Panzer IV (with its sibling in the background) is forced to tumble around on the ground.

This is done to test how impacts are registered on the various components on the tank. The different components can be seen in the debug info field in the top right. 

ADam is “Armor Damage” and IDam is “Internal Damage” ie, damage to the outer layer of armor and damage to the tanks internal “vital” organs. Upper part is the body, lower part is the turret.
