SD2:Marder I

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

Background
A conversion of a Lorraine artillery tractor undertaken by Major Alfred Becker of Baukommando Becker in 1942, in order to provide German units on the Eastern Front with firepower capable of taking down the T-34 and KV-1 tanks. Mounting a PaK 40 75mm anti-tank gun on the Lorraine proved to be a practical, effective solution.

Sturmgeschütz-Abteilung 200 of the 21. Panzer had some Marder I built on the Panzer 39H(f) chassis.
