Ordnance QF 3 inch howitzer was a howitzer fitted to British cruiser and infantry type tanks of the Second World War so they could fire a smoke shell in "close support" of other tanks or infantry. HE shells were also available.
Earlier British tanks were fitted with a 3.7 in howitzer, based on the QF 3.7-inch mountain howitzer.
The doctrine covering the CS tanks was to "smoke parts of the enemy force" and so isolate them from the battle [1] so the gun tanks could deal with the remainder with a local, if temporary, numerical advantage [2]
While on most tanks the howitzer replaced the turret armament, on the early marks of the Churchill tank, the howitzer was fitted in the front of the hull which, although it allowed the tank to retain its main gun, limited the range and arc of fire.

A field artillery version seems to have been developed or under development in 1941 [lower-alpha 1]
Later in the war a larger QF 95 mm howitzer was employed for the same purpose.
The Infantry Tank Mark II, best known as the Matilda, was a British infantry tank of the Second World War.
The Tank, Infantry, Mk IV (A22) Churchill was a British infantry tank used in the Second World War, best known for its heavy armour, large longitudinal chassis with all-around tracks with multiple bogies, its ability to climb steep slopes, and its use as the basis of many specialist vehicles. It was one of the heaviest Allied tanks of the war.
The Tank, Infantry, Mk III, Valentine was an infantry tank produced in the United Kingdom during World War II. More than 8,000 of the type were produced in eleven marks, plus various specialised variants, accounting for approximately a quarter of wartime British tank production. The many variants included riveted and welded construction, petrol and diesel engines and a progressive increase in armament. It was supplied in large numbers to the USSR and built under licence in Canada. It was used extensively by the British in the North African campaign. Developed by Vickers, it proved to be both strong and reliable.
The Cromwell tank, officially Tank, Cruiser, Mk VIII, Cromwell (A27M), was one of the series of cruiser tanks fielded by Britain in the Second World War. Named after the English Civil War-era military leader Oliver Cromwell, the Cromwell was the first tank put into service by the British to combine high speed from a powerful, reliable engine and reasonable armour. The intended dual-purpose high velocity gun could not be fitted in the turret, so a medium velocity dual purpose gun was fitted instead. Further development of the Cromwell combined with a high velocity gun led to the Comet tank.
The Tank, Cruiser, Mk I (A9) was a British cruiser tank of the interwar period. It was the first cruiser tank: a fast tank designed to bypass the main enemy lines and engage the enemy's lines of communication, as well as enemy tanks. The Cruiser Mk II was a more heavily armoured adaptation of the Mark I, developed at much the same time.
The Tank, Cruiser, Mk II (A10), was a cruiser tank developed alongside the A9 cruiser tank, and was intended to be a heavier, infantry tank version of that type. In practice, it was not deemed suitable for the infantry tank role and was classified as a "heavy cruiser".
The Comet tank or Tank, Cruiser, Comet I (A34) was a British cruiser tank that first saw use near the end of the Second World War, during the Western Allied invasion of Germany. The Comet was developed from the earlier Cromwell tank and mounted the new 17 pdr High Velocity (HV) gun, in a lower profile, partly-cast turret. This gun was effective against late-war German tanks, including the Panther at medium range, and the Tiger.
The Ordnance Quick-Firing 17-pounder was a 76.2 mm (3 inch) gun developed by the United Kingdom during World War II. It was used as an anti-tank gun on its own carriage, as well as equipping a number of British tanks. Used with the APDS shot, it was capable of defeating all but the thickest armour on German tanks. It was used to 'up-gun' some foreign-built vehicles in British service, notably to produce the Sherman Firefly variant of the US M4 Sherman tank, giving British tank units the ability to hold their own against their German counterparts. In the anti-tank role, it was replaced after the war by the 120 mm BAT recoilless rifle. As a tank gun, it was succeeded by the 84 mm 20 pounder.
The infantry tank was a concept developed by the United Kingdom and France in the years leading up to World War II. Infantry tanks were designed to support infantrymen in an attack. To achieve this, the vehicles were generally heavily armoured to allow them to operate in close concert with infantry even under heavy fire. The extra armour came at the expense of speed, which was not an issue when supporting relatively slow-moving foot soldiers.
The Ordnance Quick-Firing 6-pounder 7 cwt, or just 6-pounder, was a British 57 mm gun, serving during the Second World War as a primary anti-tank gun of both the British and United States Army. It was also used as the main armament for a number of armoured fighting vehicles.
The Ordnance QF 2-pounder, or simply "2 pounder gun", was a 40 mm (1.575 in) British anti-tank gun and vehicle-mounted gun employed in the Second World War.
The Alecto, initially known as the Harry Hopkins Mk 1 CS, was a self propelled gun developed by the British during World War II.
The Tank, Cruiser, Ram was a cruiser tank designed and built by Canada in the Second World War, based on the U.S. M3 Medium tank chassis. Due to standardization on the American Sherman tank for frontline units, it was used exclusively for training purposes and was never used in combat as a gun tank. The chassis was used for several other combat roles however, such as a flamethrower tank, observation post, and armoured personnel carrier.
The Tank, Heavy, TOG 1 was a prototype British heavy tank produced in the early part of the Second World War in the expectation that battlefields might end up like those of the First World War. It was designed so it could cross churned-up countryside and trenches. A single prototype was built, and followed by an improved model, but interest faded with the successful performance of another cross-country design, the Churchill tank, and the mobile war that was being fought.
The Ordnance QF 75 mm, abbreviated to OQF 75 mm, was a British tank gun of the Second World War. It was obtained by boring out the Ordnance QF 6-pounder 57 mm anti-tank gun to 75 mm, to give better performance against infantry targets in a similar fashion to the 75 mm M3 gun fitted to the American Sherman tank. The QF came from "quick-firing", referring to the use of ammunition where the shell has a fixed cartridge. The gun was also sometimes known as ROQF from Royal Ordnance Quick-Firing.
This article lists British armoured fighting vehicle production during the Second World War. The United Kingdom produced 27,528 tanks and self-propelled guns from July 1939 to May 1945, as well as 26,191 armoured cars and 69,071 armoured personnel carriers.
The Ordnance QF 32 pounder or (32-pdr) was a British 94 mm gun, initially developed as a replacement for the Ordnance QF 17-pdr anti-tank gun.
The Ordnance QF 95-mm howitzer was a British howitzer built in two versions during the Second World War. The tank howitzer version was accepted for service use, but the infantry version was not.
