History

Collar Tabs for foreign units in the Wehrmacht were introduced on May 29, 1943. There may have been different collar tabs specifically made for foreign troops before this date, but more information on this is needed.
They usually have insignia in silver tress on a dark backing with coloured piping.

Member of Turk units wore patches with piping in a colour determined by their region of origin. Piping for units from Turkistan is light blue, light green for units from Azerbaijan, pink for units from Georgia, golden-yellow for units from Armenia, and brown for units from North Caucasus.

Patches for Lieutenant Colonel rank have a dark blue-green base with aluminum braid all around, with one bar parallel to the front edge braid and one gold-coloured pip.
