What is a Tank, Anyway?
In three words: Mobile Protected Firepower. Implicitly, it is also ground-based. This discussion will involve three other somewhat related but important qualities — autonomy, responsiveness, and availability — which will be covered in more detail later. However, Mobile Protected Firepower is the fundamental nature of the tank.
A tank is mobile because it moves faster than a man on foot; also, practically, it moves faster over certain terrain types than motor transport vehicles. It is protected likewise because it requires more firepower to kill than a man on foot. And it itself has more firepower than a man on foot. The comparison to the infantryman is not only for historical reasons but because he is the fundamental component of warfare.
