In the 1950s, a company called H.L. Yoh submitted several ideas for new tanks and vehicle improvements to the U.S. Army. Each of their projects featured unique shapes and innovative mechanics that seemed more or less feasible to implement. Collectively, these vehicles have been dubbed Yoh tanks. While they never reached the prototype phase or gained much attention from the U.S. Army, their unusual look and original features are well worth a closer inspection.
Let’s check out some of the ideas and proposals by the H.L. Yoh company that inspired the new branch of American heavy tanks in World of Tanks, even though not all of the ideas will find their way into the game.
Gun Shield and Turret Concepts

The new gun shield incorporated many desirable factors. The primary feature consisted of the weight being concentrated aft of the trunnion, helping to balance the gun. The shield was composed of a lightweight cast core to which the gun cradle was attached, permitting the gun to recoil. The sloped front provided excellent obliquity. The turret opening was completely sealed by the unique contour that maintained a minimum gap between the shield and turret.
