Oh MONRAD,
By definition, a "tank" is any fully tracked AFV with a turret mounted large caliber weapon system designed to be employed in combat to defeat the enemy by maneuver, firepower and tactics when used in combination with air support, artilllery and infantry (read Blitzkreig, or more recently Combined Arms Operations).
