Although the duel armor and the projectile won the last, the designers have continued the search for reserves the survivability of tanks and seemed to have found a way out of the impasse. So, relying on the blitzkrieg, Hitler’s engineers created a high-speed machine guns 37-55 mm caliber and two or three machine guns.
