Colonel Bravo character jug produced at Mayer Pottery of Trenton, New Jersey, circa 1890. Colonel is a senior military officer rank used in many countries. It is also used in some police forces and paramilitary organizations. In the 17th, 18th and 19th centuries, a colonel was typically in charge of a regiment in an army. Modern usage varies greatly, and in some cases, the term is used as an honorific title that may have no direct relationship to military service. The rank of colonel is typically above the rank of lieutenant colonel. This brave colonel has earned the nickname Colonel Bravo by his troops for his brave and sometimes daring tactics used during conflict.
