The 2 cm Flakvierling 38 was vehicle towed anti-aircraft gun used by German forces during world war II. Apart from the towed version, it was also used as for self-propelled guns. It joins four automatic cannons with a newly designed carriage. The Flakvierling 38 was more reliable and quick firing than its predecessor. The block 2186 of the gun rotates round its own axis and moves up and down.
