Tribune (Latin: Tribunus "Tribal Officer") - Commanders of the six Cohorts which comprised a Legion, were members of a Legate's (Legatio's) Staff, sometimes termed Senior or Junior to designate rank.The Tribune assigned as second in command of the Legion was drawn from the Senatorial Class and was titled as "Tribunus Laticlavius". The other five junior Tribunes termed "Tribunus Angusticlavius" came from the Equestrian Class and were in the midst of their careers. They were primarily administrative and had no defined military command responsibilities.
