The 15 cm Autokanone M. 15/16 was a heavy field gun used by Austria-Hungary in World War I. Guns turned over to Italy as reparations after World War I were taken into Italian service as the Cannone da 152/37. Austrian and Czech guns were taken into Wehrmacht service after the Anschluss and the occupation of Czechoslovakia as the 15.2 cm K 15/16(t). Italian guns captured after the surrender of Italy in 1943 were known by the Wehrmacht as the 15.2 cm K 410(i). They weren't used much by the Germans, probably because of their unique ammunition, and generally served on coast-defense duties during World War II.

The M. 15 was a thoroughly conventional design for its day with a box trail, iron wheels and a curved gunshield. It was notable as being the first Austro-Hungarian gun to be designed for motor transport, hence the Autokanone designation. For transport the barrel was generally detached from the recoil system and moved on its own trailer. The original M. 15 weapons had a maximum elevation of only 30°, but an elevation of 45° was demanded early in the gun's production run, mainly to engage high-altitude targets in the mountains. 27 M. 15 guns were completed before production switched to the improved M. 15/16 with greater elevation in the first half of 1917. A total of 44 barrels and 43 carriages were completed by the end of the war[1].
It seems likely that surviving M. 15 guns were rebuilt after the war to M. 15/16 standards. During the Twenties, guns in Italian service had been refurbished by Vicker-Terni and given new wheels.
