[edit] Development

By the early 1920s the French army realized the armour-piercing capability of the 37 mm TRP infantry gun would be insufficient against modern tanks. In 1926 Hotchkiss proposed a 25 mm in-house design that was eventually accepted for service in 1934, under the designation canon de 25 mm semi-automatique modèle 1934 (generally shortened to canon de 25) . At the outbreak of WWII, it was the main anti-tank weapon of the French infantry.

[edit] Foreign use

When it landed in France in 1939 the British Expeditionary Force had insufficient numbers of anti-tank weapons such as the Ordnance QF 2 pounder. They were issued canons de 25 which became known as Anti-Tank Gun, 25-mm. Hotchkiss, Mark I on 25-mm. Carriage, Mark I in British service.

Examples captured by the German forces were operationally used under the designation 2.5cm Pak 112(f).

In 1935 Hotchkiss 25 mm anti-tank gun was purchased for evaluation by the US Army^[1].
