The Führer Grenadier Brigade (formerly Führer Grenadier Battalion later Führer Grenadier Division) was an élite German Army combat unit which saw action during World War II. The Führer Grenadier Brigade is sometimes mistakenly perceived as being a part of the Waffen-SS, whereas it was actually an Army unit and technically assigned to the Großdeutschland Division. This misconception comes from its original duty of guarding Adolf Hitler's East Prussian Wolfsschanze Headquarters, a task which sounded similar to the original one of Waffen-SS 1. Panzer Division "Leibstandarte SS Adolf Hitler", which in turn stemmed from the Führer's original bodyguard corps. Fighting on both the Eastern and Western Fronts, the brigade surrendered to U.S. forces in Austria in 1945.
