The A22 Infantry Tank Mark IV Churchill was the first British tank to be designed entirely during World War II.

It remained in production throughout the war and was one of the most popular British tanks during the war.

The first model, which had a 3 inch (76.2 mm) close support howitzer in its nose and a 2 pounder gun in its turret, was built in 1941.

The Churchill had thick armor and performed well cross country, although it was slow.

It was the first British tank to mount US 2.95 inch (75 mm) guns after guns and mantlets were salvaged from Sherman tanks that were knocked out in Tunisia.

Because they were built so quickly, there were many problems with the early A22s, including frequent breakdowns.

The size of this tank was limited by the loading gauge restrictions of the British railway.

By 1944-45, the A22 was undergunned compared to German tanks, although its heavy armor compensated for this.

Nevertheless, the Churchill was very adaptable and was used for many different specialized roles during the 1944 invasion of Europe. These specialized tanks were known as the Funnies.  They included:

  • Churchill Ark Mark I, Mark II and Mark III - These carried bridges and were used to span defense craters and ditches or to lay ramps across sea walls
  • Churchill Armoured Vehicle Royal Engineers (AVRE) Mark I and Mark II - They carried assault engineers who were sent to breach heavy defenses. The Churchill AVRE had an 11.42 inch (290mm) spigot mortar for demolition tasks as well as a two speed winch, an earth spade at the rear and demountable jibs at the front and rear
  • Churchill with Bobbin/Twin Bobbins - Had mat layers which were used at beach landings.
  • Churchill Anti-Mine Roller Attachment (AMRA), Anti-Mine Reconnaissance Castor Roller (AMRCR), Canadian Indestructible Roller Device (CIRD), Plough, Snake, Conger - These were used to detonate mines. They had various mine-clearing systems, which were usually front-mounted.
  • Churchill with Mine Plough (A-D, Farmer, Bullshorn/Jeffries Ploughs)
  • Churchill Oke/Crocodile -These had flamethrowers.
