The 8 cm kanon vz. 30 (Cannon model 30) was a Czech field gun used in the Second World War. Guns captured after the German invasion of Czechoslovakia in March 1939 were taken into Wehrmacht service as the 8 cm FK 30(t). It was used by a variety of German units during World War II, including I./SS-Artillerie-Abteilung 3 between 1939 and 1940.
It was modified from an earlier Skoda design, the 7.5 cm kanon vz. 28, that attempted to combine the field, mountain and anti-aircraft roles into one weapon. It proved to be fairly successful at the first two, but was a failure at the third. The Czechs decided to adopt it to replace their plethora of aged Austro-Hungarian field guns. They deleted the firing platform of the original design and modified it to use standard Czech ammunition. It shared the same carriage that could break down into three pieces for transport as the 10 cm houfnice vz. 30.
