Interesting question, I had my doubts so started googling away and found only three units have cuff titles. They are:
The German Army Aviation Corps - contains all of the army's helicopter units.
Panzerlehrbrigade 9 - Armoured Training Battalion (and School)
Wachbataillon -
Drill, ceremonial and guarding and security duties
From the numerous photos I came across, these are only worn on dress/service uniforms and not on combat fatigues.
A great site click here:
