The 12 cm Kanone M 80 was a light siege gun used by Austria-Hungary during World War I.

The steel-bronze[1] (see Franz von Uchatius) was considered inferior to steel as early as 1870s, but due to the lack of steel industry in Austria it was used for the barrel, and the iron carriage lacked any system to absorb recoil other than the traditional recoil wedges placed underneath and behind the wheels of the carriage.

These wedges helped to absorb the recoil force and encouraged the wheels to run forward to bring the gun back into battery.

Generally a wooden firing platform was constructed for these guns in action to provide a level and smooth surface.

While designed to penetrate the walls of fortifications the 12 cm siege gun was no longer useful against modern armored fortresses by the outbreak of World War I and its combination of long-range and light weight saw many in the field to fill the need for long-range artillery.
