Minor variation&#8217;s were the Mk 4 NA 75 locally fitted with the US 75mm gun replacing the 6 Pdr used in Italy. The Crocodile was a Mk 7 with a flame thrower and trailer and the Mk 8 a CS Mk 7 with a 95mm Howitzer. The AVRE was a modified Mk 4 or 3 with a Petard spigot mortar and there were other up armoured versions (Mk&#8217;s 9, 10 and 11) from early 1945, plus many experimental types (E.g. 3 in Gun carrier) and various turret less vehicles like the Ark and ARV&#8217;s. The Churchill saw action from 1942 until the end in Europe, middle and far east, Russia and then on to Korea in 1950. The final user was the Irish Army which still had up armoured versions as late as about 1969.
