The Boys anti-tank rifle (officially Rifle, Anti-Tank, .55in, Boys, and sometimes incorrectly spelled "Boyes"), is a British anti-tank rifle used during the World War II, 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 (Mark I) which had a circular muzzle brake and T-shaped monopod, built primarily at Birmingham Small Arms, BSA in England; a later model (Mk I*) built primarily at the John Inglis and Company in Toronto, Canada, that had a rectangular muzzle brake and a V shaped bipod; and a third model made for airborne forces with a 30-inch (762 mm) 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 PIAT hollow charge weapon mid-war.

Design and development

The firearm was developed by Captain (British Army and Royal Marines), Captain Henry C. Boys, Assistant Superintendent of Design—1885-1937, who was a member of the British Small Arms Committee and a designer at the Royal Small Arms Factory, Enfield Lock, Enfield. It was initially called ''Stanchion'' but was renamed after Boys 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 (firearm), magazine, the weapon was large and heavy with a bipod at the front and a separate grip below the padded Stock (firearm), butt. In order to combat the recoil caused by the large 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 Rim (firearms)#Belted, belt added firing a bullet. At its introduction, the weapon was effective on light armour thick at . Two main service loads were used during the Second World War: The W Mark 1 a AP projectile fired at , and the W Mark 2 ammunition, AP at . The W Mark 1 could penetrate of armour at , 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 . The Boys' effective range against unarmoured targets (for example, infantry), was much greater. Despite its recoil slide and rubber-cushioned buttpad, the recoil of the weapon (along with noise and muzzle blast) was said to be painful, frequently causing neck strains and bruised shoulders. Consequently, the Boys was almost never fired as a free weapon (that is, not affixed to a support) except in emergencies.

Operational use

The Boys rifle was used in the early stages of the Second World War against lightly vehicle armour, 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 Battle of France, France and North Africa Campaign, 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 Government of Canada, Canadian government, through the Directorate of Military Training, Department of National Defence (Canada), The Department of National Defence and National Film Board of Canada (NFB) commissioned a training film, ''Stop That Tank!'' (1942), from Walt Disney Studios (division), Walt Disney Studios to counter the rifle's "jinx" reputation. Nonetheless, in the European theatre, it was soon replaced by the PIAT (Projector, Infantry, Anti-Tank) 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 (AP), armour-piercing incendiary (API), and armour-piercing incendiary tracer (APIT) 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 Breda Model 35, 20mm Breda cannon. The weapon was standard issue to British and Commonwealth forces which attempted to stem the Japanese onslaught through the Pacific War, Pacific theatre. At Battle of Milne Bay, Milne Bay, the weapon proved completely ineffective. It also failed to stop List of Japanese tanks and armoured vehicles of the WWII period, Japanese tanks in British Malaya, Malaya. Some accounts claim that the 1st Punjab Regiment, 1/14th Punjabi Regiment knocked out two light Japanese tanks at a roadblock. During the Battle of Singapore, the The Cambridgeshire Regiment, 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 fight 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 Raiders, Marine Raider Battalions against enemy bunkers and aided in the destruction of 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 of the Philippines, Japanese occupation and to aid the Philippines Campaign (1944-45), Allied liberation. Following the Post-Second World War era, it was operated during the Hukbalahap Rebellion against the Hukbalahap Communist fighters in Luzon, Central Luzon and by the Philippine Expeditionary Forces to Korea, Philippine Expeditionary Forces to Korea (PEFTOK) against the North Korean and Chinese Communist forces. In September 1965, members of the Irish Republican Army (1922–1969), IRA hit the British fast-attack patrol boat HMS ''Brave class fast patrol boat, Brave Borderer'' with a Boys rifle, crippling one of her turbines while she was paying a visit to Waterford, Republic of Ireland.

Performance

The contemporary training manuals for the Boys directed that it was for protecting the platoon against light armoured fighting vehicles: penetrating "their armour up to about 500 yards range" and "inflict casualties on their crew, although it may not seriously damage the vehicle itself." A manual on the Boys published for the Home Guard in 1944 gave the expected performance against armour ranging from 0.91 in (22.3 mm) at 100 yards square on to 0.35 in (8.8 mm) at 500 yards hitting at a 40 degree angle. The manual also noted that maximum penetration against other materials was of brick walls and of sandbags.
