機甲師団
On 14 December, Panzerbrigade 150 was assembled near Bad Münstereifel and on the afternoon of 16 December it moved out, advancing behind the three attacking Panzer divisions, the 1st SS Panzer Division, the 12th SS Panzer Division, and the 12th Volksgrenadier Division, with the aim of moving around them when they reached the High Fens. However, when the 1st SS Panzer Division failed to reach the start point within two days, Skorzeny realized that Operation Greif's initial aims were now doomed.
