It was a long time tradition for the army of the Austro-Hungarian Empire to use mountain guns, and in the beginning of the 20th century, mountain guns Mark 75 and Mark 99 were widely used. These types, however, were becoming outdated quite quickly becauseof rapid development of artillery techology of those times. The Skoda Works in Pilsen, a traditional supplier of artillery armament, had since the beginning of the century been developing several projects of mountain guns with various calibers. When a 7cm Gebirgskanone M.9 had been built in small production run, a new and heavier caliber (7.5cm) gun was developed, which eventualy became to be produced in 1912, mainly on basis of an interest from foreign customers. The last production batch of this gun, that had been intended for Chinese government, was taken over by the Austro-Hungarian Army and put into service as a 7.5cm Gebirgskanone M.14. But, already a year ago those guns had been tested by the military and requirements for a new model of a mountain gun had been defined. As the First World War broke out, it accelerated everything. Prototype guns with some improvements made on basis of requirements from the military were tested during 1914 and production of the new model followed shortly. The new gun was put into the service with the Austro Hungarian army as a 7.5cm Gebirgskanone M.15. It was possible to dismantle the weapon to six main components that were to be carried by draught animals. Another three horses or mules carried the ammunition shield, the sights and standby supply of ammunition.
