Operation Panzerfaust
The second Budapest mission, Operation Panzerfaust, can be said to have been, officially, the 600's first mission although the new battalion was not formally mustered until 9 November 1944 in Neu-Strelitz, their garrison town. The soldiers of the 500th who survived long enough to see the formation of the 600 were also given back their previous ranks and the right to wear the sig rune on 9 November 1944.
