The 7 cm Gebirgsgeschütz M 75 was a bronze-steel mountain gun used by Austria-Hungary during World War I. Despite its 7 cm designation it actually fired a 66 mm (2.6 in) projectile. The Austro-Hungarian Army rounded up to the nearest centimeter for their designations. The gun had an early form of Krupp horizontal sliding-block breech and it fired separate-loading, bagged charges and projectiles. Due to its low profile, its breech could recoil into the ground so its angle of elevation was restricted which was a significant handicap for a mountain gun which needed high angles of elevation. For transport, the Gebirgsgeschütz M 75 could be broken down into two loads.
