Green beret
U.S. Special Forces wear the green beret as a distinction of excellence and uniqueness within the Army.
Guías de Navarra
The Carlist troops had lacked a regular uniform and had used instead the black beret that was already worn in the Basque region. Zumalacárregui gave these troops distinctive red berets, purchased in France, as a type of uniform. At first, the red berets were accepted with joy by Carlist officers, but they then realized that Liberal sharpshooters found the red berets to be a good target. The red berets were thus retired and hidden in a house in Eulate. When he created the Guías de Navarra, Zumalacárregui ordered that these red berets be brought to him and given to this new battalion, which was, in any case, used for the most dangerous missions.
