British armor doctrine in the 1930s up to the outbreak of WWII called for 2 types of tank - more mobile cruiser tanks and heavy, slow infantry tanks. The Valentine was a prolifically produced example of the latter 7,315 units, more than 30 of British tank production in WWII. It was based upon existing cruiser tank designs and relatively easy to manufacture, a critical point for the British military after it had lost so much material during the Dunkirk evacuation in 1940. The Valentine would see extensive action in North Africa, particularly the Mk.II and Mk.IV variants they had different engines depicted by this kit. Over 4,500 were also handed over to the Soviet Union under the lend-lease agreement, the Red Army using them mainly for recon work.
