The development of the [[tank]] during [[World War I]] prompted some nations to experiment with forming them into division-size units. Many did this the same way as they did cavalry divisions, by merely replacing cavalry with [[armoured fighting vehicles|AFVs]] (including tanks) and motorizing the supporting units. This proved unwieldy in combat, as the units had many tanks but few infantry units. Instead, a more balanced approach was taken by adjusting the number of tank, infantry, artillery, and support units.

The terms "tank division" or "mechanized division" are alternative names for armored divisions. A "[[Panzer division]]" was an armoured division of the ''[[Wehrmacht]]'' and the ''[[Waffen-SS]]'' of Germany during [[World War II]].

Since the end of the war, most armoured and infantry divisions have had significant numbers of both tank and infantry units within them. The difference has usually been in the mix of battalions assigned. Additionally, in some militaries, armoured divisions are equipped with more advanced or powerful tanks than other divisions.
