The Tank, Cruiser, Mk I (A9) was a British cruiser tank of the interwar period. It was the first cruiser tank: a fast tank designed to bypass the main enemy lines and engage the enemy’s lines of communication, as well as enemy tanks. A total of 125 were built. It was an effective tank in the French, Greek and early North African campaign, until the introduction of more heavily armoured Axis tanks.
