Hello Sergeant. Brandenburgers were the German Armys version of out future Green Berets. There was even a Panzergrenadier Division named Brandenburg.

They started out as a Construction Training Company, that eventually became Panzergrenadier Division Brandenburg.

On June 26 1942 they were known as: Training Regiment Brandenburg z.b.V. 800 and were qualified as being battle ready by the German High Command.

The unit was scattered for billeting in: Havel, Freiburg in Bresigau for regmt #1.
Rgmt #2 in Duren, and also in Weilburg/Baden.
