Oerlikon 20mm cannon is an anti-aircraft gun of Swiss origin.
Based on an original German 20mm Becker design that appeared very early in World War I, the 20mm Oerlikon was widely produced by Oerlikon Contraves, with various models employed by both Allied and Axis forces during World War II.
While primarily designed for anti-aircraft warfare, the Oerlikon can also be used against ground units thanks to its high rate of fire, making it a dangerous weapon to infantry and lightly armoured vehicles.
In Battlegroup42, the 20mm Oerlikon is mostly found in its single mount variant, and it is the primary anti-aircraft weapon for France and Yugoslavia. It is also used as a mounted weapon on ships for both sides. The twin mount version can only be found on ships.
The weapon is also known by the French designation "2 cm mitrailleuse C.A. Oerlikon" in the mod.
