Here are some definitions of the word "tank"[SIZE=-1]
Slower? it went about as fast as the Tiger Iits just asking for a slower, but more heavily armored Tiger 1 tank basically.
Numerous statements have been made that the Tiger II was too heavy, too big, too slow, "a casemate", etc. One is left with the impression that it was lucky to move at all. These banal generalities, stated as incontrovertible facts, are never substantiated by actual specifications, test reports or after-action accounts from the units that used the Tiger II. In spite of these frequently repeated remarks, the capability of the Tiger II to negotiate obstacles and cross terrain was equivalent to or better than most German and allied tanks.
