I've been playing the game War Thunder recently. It is common knowledge in the game that angling a tank's armor, even slightly, will significantly increase the effectiveness of protection against enemy fire. This led me to wonder: was the concept of angling tank armor consciously employed or recognized as a doctrine during World War II?
I understand that sloped armor, such as that used on the German Panther or the Soviet T-34, was designed to increase the chances of deflecting incoming rounds by creating an oblique impact angle. It seems that tank designers during the war were aware of this concept, as it effectively increased the thickness of the armor relative to the incoming shot. However, I’m curious if there was formal military doctrine that instructed tank crews to actively angle their vehicles in combat to take advantage of this phenomenon, or if this was more of a result of battlefield improvisation or tactical adaptation?
Were there any notable examples where angling armor was explicitly trained for or utilized in combat?
