  • Very inaccurate with extended bursts
  • Slow reload


The MK 103/38 was developed as an anti-aircraft twin-mount variant of the MK 103, a dual-purpose anti-armour and air-to-air autocannon developed by Germany in World War II. With the gradual loss of the Luftwaffe (German Air Force) starting in 1943, the Germans began aggressively developing new self-propelled anti-aircraft designs to counter the threat of Allied bombers. While the first generation models like the Wirbelwind and Ostwind were open-topped designs, the Germans were moving towards a newer fully enclosed vehicle for better crew protection. At the same time, the increasing inadequacies of their main anti-aircraft gun, the FlaK38 led to larger, more powerful guns being used for these new designs. The airborne MK 103, in a twin-mounted purpose-built oscillating turret, was mounted on the chassis of the Pz.IV, creating the Kugelblitz (ball lightning). However, the state of German industry late in World War II meant that only five prototypes were built.


Excellent additions to the article would be video guides, screenshots from the game, and photos.
