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.
M 14 and M14/16 howitzers captured by Italy during the war and received as reparations after the war, when they were put into service with the designation of Obice da 149/13. Some 490 were on hand in 1939 and weapons captured by the Germans after the Italians changed sides in 1943 were used as the 15 cm sFH 400(i). Surviving weapons were impressed into German service after 1943 as the 15 cm sFH 401(i). Czech and Slovak weapons were known as the 15 cm hrubá houfnice vz. 14 and 14/16.
