(3) Panzer 4 ...1941 Changes
In 1941, as more powerful guns were being used against tanks, 1.50 inches of additional armor plate was bolted against the plates on the front of the superstructure and on the upper and lower nose-plates. The 1.20-in. basic plates were face-hardened to a Brinell hardness of 600 to 800 and 1.25-in additional plates were the same. About a year later, in January 1942, the tank appeared with a basic armor of 1.97 inches on the front and back, the side-armor thickness remaining unchanged at 1.50 inches. This armor was chromium-molybdenum and performed well against monobloc shot.
(4) 1942 changes
Therefore, in June 1942, a .79-inch additional plate was bolted on the gun mantlet and front superstructure as a means to defeat a shot with a piercing cap. Between this plate and the basic armor was an air gap or space, varying from 4 to 8 inches. The plate conformed roughly to the shape of the section covered. The spaced armor seems to have been a field expedient, resulting undoubtedly from the demonstrated fact that the spare section of track carried on the front of German tanks gave additional protection. This method of adding armor was officially recognized, as later models had brackets fitted for installing spaced armor when desirable.
now tell me a piece of shrapnel from a bomb dropped at any diistance would penetrate that with the ease it does in this game.
if you actually believe that you need a physics lesson.
