SD2:Sd.Kfz. 10/4

 is a German Anti-air unit in Steel Division II.

Background
The smallest German half-track, Sd.Kfz. 10 was designed by Demag between 1934 and 1938, immediately entering service once the design phase was concluded. The Sd.Kfz. 10 was a versatile light vehicle used primarily as a prime mover for smaller towed guns, such as the 2 cm FlaK 30 or the 3.7 cm PaK 36 anti-tank gun, capable of carrying up to 8 soldiers in addition. About 14,000 were produced until the end of the war, making it one of the most ubiquitous and versatile designs of Reich.

The 10/4 designation refers to a converted haltrack carrying the 2 cm FlaK 30 autocannon on a special platform with folding panels. It was designed to provide mobile formations with anti-aircraft protection and served until the end of the war.
