For the UK regiments, the Centurion was the primary British tank of the post-Second World War period. Development of the tank began in 1943 and manufacture of the Centurion, began in January 1945. With the 20-pounder gun it first entered combat with the British Army in the Korean War in 1950, in support of the UN forces. It was noted for its high mobility, able to climb to the top of hills that were considered difficult for infantry, let alone tanks. Upgraded to mount the 105 mm L7 gun, it became the UK's first main battle tank.
