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. A further limitation was that the Boys rifle was relatively heavy and unwieldy to carry. 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 (NFB) commissioned a
training film,
Stop That Tank! (1942), from
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
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, at least one of the two
Type 95 tanks was perforated by several shots from a Boys. During the
Battle of Jitra a Boys gunner of the
1/14th Punjabi Regiment knocked out two light Japanese tanks, blocking the bridge that was the route of Japanese advance. The Boys rifle was also equipped and used by the
Philippine guerrilla and resistance forces as well as the
United States Army Forces in the Philippines – Northern Luzon (USAFIP-NL) during the
Second World War against the
Japanese occupation and to aid the
Allied liberation. In the post-Second World War era, it was operated by the
Armed Forces of the Philippines including
Philippine Army and
Philippine Constabulary during the
Hukbalahap Rebellion against the Hukbalahap Communist fighters in
Central Luzon and by the
Philippine Expeditionary Forces to Korea (PEFTOK) 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, Ireland. ==Performance==
