A-9 

Type: Cruiser tank

Nationality: Great Britain

Named A-9 or Cruiser Mark I. The British doctrine planned, besides infantery tanks, a "Cruiser" tank for the armor mission in large tank units. The A-9 was the first tank aimed at that.
The A-9 was far from perfect. Its armor was flimsy and it was mechanically fragile. It represented the quarter of all cruiser tanks at the onset of the war. It took part in the campaign in France and then fought in Africa against the Italians.
Its intervention in Greece in 1941 cost much due to numerous mechanical breakdowns. It appeared for the last time on the battlefield during the disastrous operation "Battleaxe" in June 1941.
Identification: Like the Valentine or the A-10, it had an running gear with two bogies with three road-wheels each. Its tracks were narrower than those of the Valentine, whereas it had an auxiliary turret with MG's in front of the vehicule, while the A-10 had none.
