Boys anti-tank rifle


The Rifle, Anti-Tank,.55in, Boys, commonly known as the "Boys Anti-tank Rifle", was a British anti-tank rifle in use during the Second World War. It was often nicknamed the "elephant gun" by its users due to its size and large bore.
There were three main versions of the Boys: an early model which had a circular muzzle brake and T-shaped monopod, built primarily at BSA in England; a later model built primarily at the John Inglis and Company in Toronto, Ontario, Canada, that had a square muzzle brake and a V shaped bipod; and a third model made for airborne forces with a 30-inch barrel and no muzzle brake. There were also different cartridges, with a later version offering better penetration.
Although adequate against light tanks and tankettes in the early part of the war, the Boys was ineffective against heavier armour and was phased out in favour of the hollow charge weapon PIAT mid-war.

Design and development

The eponymous creator of this firearm was Captain Henry C. Boys who was a member of the British Small Arms Committee and a designer at the Royal Small Arms Factory, Enfield. It was initially called Stanchion but was renamed after Captain Boys as a mark of respect when he died a few days before the rifle was approved for service in November 1937.
A bolt action rifle fed from a five-shot magazine, the weapon was large and heavy with a bipod at the front and a separate grip below the padded butt. In order to combat the recoil caused by the large 0.55 inch round, a muzzle brake was fitted on the barrel while the receiver was allowed to slide along the frame with a shock absorber attached to the rear of the rifle. The Boys had been designed with numerous small narrow-slotted screws of soft steel set very tight into the body of the weapon and its repair and maintenance proved difficult.
The.55 Boys cartridge was an adaptation of the.50 BMG, with a belt added firing a 47.6 gram bullet. At its introduction, the weapon was effective on light armour at 100 yards.
There were two main service loads used during the Second World War: The W Mark 1 and the W Mark 2 ammunition. The W Mark 1 could penetrate 23.2 mm of armour at 100 yards, about the thickness used on the frontal armour of a half-track or armoured car, or the side or rear armour of a light tank. Later in the conflict, a more effective round was developed, the W Mark 2, which fired a tungsten-cored projectile at 945 m/s. The Boys' effective range against unarmoured targets, was much greater.
Despite its recoil slide and rubber-cushioned buttpad, the recoil of the weapon was said to be painful, frequently causing neck strains and bruised shoulders. Consequently, the Boys was almost never fired as a free weapon except in emergencies.

Operational use

The Boys rifle was used in the early stages of the Second World War against lightly armoured German tanks and combat vehicles. Britain also supplied a large number of Boys anti-tank rifles to Finland in 1939 and 1940 during the Winter War with the Soviet Union. The weapon was popular with the Finns because it could deal with Soviet T-26 tanks, which the Finnish Army encountered in many engagements.
Although useful against early German and Italian tanks in France and North Africa, as well as in the Norwegian campaign, such as the Panzer I, Panzer II and early models of Panzer III, increases in vehicle armour during the Second World War left the Boys largely ineffectual as an anti-tank weapon. A shortened version was deployed in 1942 for issue to airborne forces and saw use in Tunisia, where it proved completely ineffective because of the reduced velocity caused by the shortened barrel. Another limitation was that the Boys rifle was relatively heavy and unwieldy to carry and set up.
The Boys' reputation after the Battle of France was such that the Canadian government, through the Directorate of Military Training, The Department of National Defence and National Film Board of Canada commissioned a training film, Stop That Tank!, from Walt Disney Studios to counter the rifle's "jinx" reputation.
Nonetheless, in the European theatre, it was soon replaced by the PIAT in 1943, which first saw service during the Allied invasion of Sicily. In other roles, the Boys saw some use against bunkers, machine gun nests and light-skinned vehicles but was rapidly replaced in British and Commonwealth service, as quantities of the latter weapon became available, by the U.S..50 BMG calibre M2 Browning machine gun.
Using armour-piercing, armour-piercing incendiary, and armour-piercing incendiary tracer ammunition, the.50 Browning was just as capable in armour penetration and more devastating when igniting thin-skinned vehicles using incendiary rounds than the Boys, and could also serve as an effective anti-aircraft weapon. The heavier Browning, however, was not "man-portable" at without tripod and with tripod. Even the British Special Air Service, which made much use of captured or cast-off weapons for their jeeps and reconnaissance vehicles, quickly got rid of their Boys rifles in favour of M2 Brownings or the Italian 20mm Breda cannon.
The weapon was standard issue to British and Commonwealth forces which attempted to stem the Japanese onslaught through the Pacific theatre. At Milne Bay, the weapon proved completely ineffective. It also failed to stop Japanese tanks in Malaya. Some accounts claim that the 1/14th Punjabi Regiment knocked out two light Japanese tanks at a roadblock. During the Battle of Singapore, the 1st Bn Cambridgeshire Regiment claims the Boys was very useful in knocking holes through walls during street fighting. After the war in the Pacific, the gun was used by Royal Malay Regiment to fought against communist insurgents during Malayan Emergency.
The U.S. Marine Corps purchased Canadian Boys rifles prior to the attack on Pearl Harbor. They saw limited use by the Marine Raider Battalions against enemy bunkers and aided in shooting down two seaplanes off Makin Island. The U.S. Army's 1st Ranger Battalion was also equipped with Boys, but they were not used in combat. The other five Ranger battalions were authorized Boys, but were not equipped with them.
The Boys rifles were also used by the Chinese Nationalist Army during the late Second Sino-Japanese War in both China and Burma.
The Boys rifle was also equipped and used by the Philippine Army and Philippine Constabulary during the Second World War against the Japanese occupation and to aid the Allied liberation. Following the Post-Second World War era, it was operated during the Hukbalahap Rebellion against the Hukbalahap Communist fighters in Central Luzon and by the Philippine Expeditionary Forces to Korea against the North Korean and Chinese Communist forces.
In September 1965, members of the IRA hit the British fast-attack patrol boat HMS Brave Borderer with a Boys rifle, crippling one of her turbines while she was paying a visit to Waterford, Republic of Ireland.

Users

The Boys Rifle was sometimes mounted on vehicles such as the Universal Carrier, Humber Light Reconnaissance Car and the Morris CS9, Standard Beaverette and Rolls Royce armoured cars.
