The 20 mm AA Machine Cannon M/38 was produced by the Danish company Dansk Industri Syndikat (Danish Industry Syndicate) - maybe better known under the abbreviation DISA - in Herlev near Copenhagen and was used by the military of Denmark in different types of mounting. This cannon was originally constructed by Colonel V. H. O. Madsen and was therefore widely known as the 20 mm Madsen Cannon. A version with a necked-out 23 mm round was also produced, generally known as the 23 mm Madsen.

The mountings were also produced by DISA in the following types:[2]

  • Light Field Mount - Primary AT mount, could be folded up and stowed on a motorcycle sidecar
  • Universal Mount - Dual purpose mount, fitted with wheels it could be towed by its crew.
  • Mobile Anti-Aircraft Mount - Dedicated AA mount.
  • Tri-axial Mount - Light weight mount intended for fortifications and naval use

There were also a number of locally designed mounts.

This type of machine cannon was a very well functioning weapon,[citation needed] which was exported by DISA to several countries.

The 20 mm machine cannons of the Danish Army were responsible for knocking out eleven armoured cars and two Panzer I's during the German invasion before the order to surrender came through.[3]
