The 15 cm schwere Feldhaubitze M 14 was a heavy howitzer which served with Austria-Hungary during World War I.

Design
The Škoda 15 cm M 14 was developed and built at the Škoda works in Pilsen. Like other guns of the time it had two crew seats mounted on the Gun shield. It broke down into two loads for transport. The M 14 was modified to improve elevation and range as well as to strengthen the carriage as the M 14/16.

Users
The successor states to the Austro-Hungarian Empire continued to use the M 14 and M 14/16 after the First World War. Postwar modifications were common to make it suitable for motor traction and to address other issues. Former enemies such as Romania and Italy also operated this series of guns whether they were captured, bought or received as war reparations after the Treaty of Versailles.
