The 15 cm schwere Feldhaubitze M 14 was a heavy howitzer which served with Austria-Hungary during World War I. 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. Postwar war modifications were common to make it suitable for motor traction and to address other issues.
