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). Due to their unique ammunition, the Germans did not use them that much, and generally served on coast-defense duties during World War II.
