Berets are usually worn at special ceremonies and roll calls, although units with a special esprit de corps, especially armoured and mechanized infantry (Panzergrenadiere) battalions, wear their berets all the time. German berets are always pulled to the right, with the badge visible over the left temple. Military bands wear the beret colour of their respective division (e.g. black in the 1st Panzerdivision).

Previously maroon beret was also experimented and even reversible (green to camo) "multi-purpose" berets were produced, but the standardization started on the 1975 military parade. In 1982 military secondary school students were issued with green berets too, while in 1987 River Force troopers received dark blue beret. After the collapse of the communism the beret as "mark of the elite trooper" received more and more popularity among soldiers. Light green (with border guard's badge) berets were issued for Border Guard reaction forces between 1990 and 2007.
