>>14740034mechs have much too many moving parts, and being bipeds/tripeds/whateverthefuckpeds makes them extremely vulnerable on the battlefield and they would not be able to move very fast. the advantage of a tank is heavy armor that is robust and mobile. if a mech is hit in the legs, it's over. virtually the entire structure will fall over and rendered inoperable. a shot out tank tread is repairable and the tank can still function well while being immobilized.
