On Tank Design

What is the Jack In A Box effect that Soviet and Russian tanks are prone to?

To understand this one must see how those of particular ideology see others.

A Collectivist will see another person as something to be used.  An Individualist will see another person as something to be protected.  One can see this in tank design.  

Western tanks (Abrams, Leopard 2, Merkava) are designed to prioritize crew protection.  Soviet (Russian) tanks don’t prioritize crew protection.  The Abrams and Leopard 2 are designed with blowout panels with blast doors for ammunition storage to protect the crew.  The Merkava series was designed with a front engine and an escape hatch in the rear to protect the crew.  Soviet (Russian) tanks are designed simply to shoot.  The crew is simply part of mechanism.
