youth leader of the German Hitler Youth (Hitlerjugend, or HJ) – Custom Printed Brick Block Figure

Based on the visual details, the figure appears to represent a German WWII Panzer (tank) Commander.

Here’s a description of the figure:

• The minifigure is wearing a black uniform, which is characteristic of German Panzer crews during World War II.
• It has a black peaked cap, also typical for Panzer commanders, featuring a diamond-shaped insignia with red and possibly white or silver elements.
• The torso printing details a black jacket with collar tabs (insignia on the collar), what appear to be silver or grey buttons, and outlines suggesting pockets and a belt.
• The legs are black with printed details suggesting creases or boots.
• The facial expression is stern.

The panda logo on the figure’s arm is likely a brand mark from the manufacturer of the custom minifigure and not part of the historical uniform.

Therefore, the character is a German WWII Panzer Commander.
