This work presents the history of the anti-tank group of the Das Reich from 1941-1944, thanks to the testimonies of two officers from this unit, the SS-Hstuf. Claudius Rupp, who would be an instructor at the Panzerjager school at Rastenburg, and the SS-Ustuf. Hans-Werner Woltersdorf. The story of this unit is illustrated by numerous photos of the engines used, including the Marder.
