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:

  • Field Mount
  • AA Defence Mount
  • Sidecar mounting with the Danish motorcycle Nimbus
  • Maritime mount

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

20 mm machine cannon in side-car mounting was without doubt the weapons system that made the most remarkable contribution[citation needed] to the defence when Germany attacked Denmark in Operation Weserübung on the 9 April 1940.
