The Gebirgskanone M.15 was an Austro-Hungarian mountain gun with a caliber of 75 mm from the First World War and the interwar period. Its first prototypes were created shortly before the outbreak of the Great War, and serial production started in 1915. The initial velocity of the projectile oscillated around 380 m / s, and the rate of fire was up to 20 rounds per minute, with a maximum shot range of 6,650 meters.
Gebirgskanone M.15 was created in the Skoda plant based in Prague, Czech Republic. It had a single-tail double-wheeled bed with a semi-automatic wedge lock. It was made of nickel-plated steel. The missiles for the Gebirgskanone M.15 were separately loaded. As a gun for mountain infantry units, it performed well. Its advantages include a relatively small weight, small size (especially width!), The ability to transport the entire gun only by soldiers, without the use of pack animals or motor vehicles, and a high rate of fire. During World War I, guns of this type were also used by the German army as an infantry support gun, in which, however, the role of the Gebirgskanone M.15 was rather poor. After 1918, production continued at the Skoda plant until the 1930s, and the gun served in the Austrian, Czechoslovak, Italian and Hungarian armies.
