The infantry tank was a concept developed by the British in the years leading up to World War II. They were intended to work alongside infantry. As such, high speed was not a requirement and they were able to carry heavier armoured. It was thought that they would develop a breakthrough in the enemy lines, opening gaps for cruiser tanks to exploit.

In practice, although able to take hits the infantry tanks were underarmed and unable to hand them out, and were left behind as tank design progressed during the war.

Well known infantry tanks include the Matilda Mk I and II, Valentine and Churchill.
