Overview
Colonel-in-chief is a ceremonial position in a military regiment. It is in common use in several Commonwealth armies, where it is held by the regiment's patron, usually a member of the royal family.
Some armed forces take a light-hearted approach to the position, appointing animals or characters as colonel-in-chief. The Norwegian Army, for example, appointed a penguin named Sir Nils Olav as a colonel-in-chief.
History
Historically a colonel-in-chief was the ceremonial head of a regiment, usually a member of a European country's royal family. The practice extends at least back to 1740 in Prussia when Frederick II held that position in the newly created Garde du Corps, an elite heavy cavalry regiment.
