Hobart's Funnies


Hobart's Funnies is the nickname given to a number of specialist armoured fighting vehicles derived from tanks operated during the Second World War by units of the 79th Armoured Division of the British Army or by specialists from the Royal Engineers.
They were designed in light of problems that more standard tanks experienced during the amphibious Dieppe Raid, so that the new models would be able to overcome the problems of the planned Invasion of Normandy. These tanks played a major part on the Commonwealth beaches during the landings. They were forerunners of the modern combat engineering vehicle and took their nickname from the 79th commander, Major General Percy Hobart.
The vehicles converted were chiefly Churchill tanks, and American-supplied M4 Sherman tanks

History

Plans to invade continental Europe were completely revised after the failure of the raid on Dieppe in 1942. Allied units in Normandy would need to overcome terrain, obstacles and coastal fortifications if the invasion were to succeed. General Sir Alan Brooke, Chief of the Imperial General Staff decided in 1943 to create special units and assigned responsibility to armoured warfare expert Percy Hobart for the development of vehicles and training crews to use them in action.
Many of the ideas had already been tried, tested or were in experimental development both by Britain and other nations. For example, the Scorpion flail tank had already been used during the North African campaign to clear paths through German minefields. Soviet T-34 tanks had been modified with mine-rollers. Close-support tanks, bridgelayers, and fascine carriers had been developed elsewhere also. However, the Funnies were the largest and most elaborate collection of engineering vehicles available.
By early 1944, Hobart could demonstrate to Generals Eisenhower and Montgomery a brigade each of swimming Duplex Drive amphibious tanks, "Crab" mine clearers, and AVRE engineer tanks along with a regiment of Churchill Crocodile flame-thrower tanks.
Montgomery considered that the US forces should use them. A third of the "funnies" were offered to the Americans of all the vehicles available, but take-up was minimal. Eisenhower was in favour of the DD tanks but left the decision on the others to General Bradley. None of the other designs was used, because it was thought that they required specialised training and an additional support organisation. Also, the Americans were reluctant to make use of funnies based on the Churchill tank as they did not want the logistical complexity of adding another tank model to their inventory.
Bradley requested 25 flail tanks and 100 Churchill Crocodiles shortly after the demonstration in February 1944 and the British War Office agreed to supply them as well as British-crewed AVREs. In the event though there was insufficient time to produce the vehicles and train the crews so on the day American forces were limited to DD tanks and their own Sherman bulldozer tanks and armoured bulldozers while 42 Assault Brigade instead of supporting the US beaches became a reserve for the British and Canadian beaches.
In light of operations during the US landing on Omaha beach, Bradley's decision has been criticised as it was felt that use of the range of "Funnies" would have saved American lives. After D-Day, American forces did make limited use of the Sherman Crab mine-clearing tank.

Designs

The majority of the designs were modified forms of the Churchill tank or the Sherman tank. Both were available in large numbers. The Churchill had good cross-country performance, heavy armour, and a roomy interior. The Sherman's mechanical reliability was valued.
Among the many specialist vehicles and their attachments were:
AVREs were also used to carry and operate equipment such as:
Many of the prototypes and their auxiliary equipment were developed by AEC.

Post-Second World War use

The Centaur bulldozer continued to be used by the British Army for some years after the Second World War and saw action during the Korean War, as did the Churchill Crocodile. Also, small numbers of Churchill AVREs and Sherman BARVs were used until the 1960s when they were replaced with similar vehicles based on the Centurion Tank. The Royal Engineers subsequently used modified Centurion and Chieftain tanks that are designed to fulfill the same roles in battle as the Funnies. The last examples of FV4003 Centurion Mk 5 AVRE 165 saw combat in the Gulf War/Operation Granby of 1991. The most recent vehicles in this line are the Titan and Trojan variants of the Challenger 2 tank.
Other nations developed their own armoured bulldozers after the war, such as the Soviet IMR variant of the T-72 tank, the US army's Rome plow, and the Israeli Armored CAT D9. Armoured bulldozers are still in use today for counter-insurgency by the Israel Defense Forces, the Egyptian army, and the Lebanese army.
