Binbas

Binbas is a common variation in spelling for the Ottoman and Turkish military rank of Binbaşı. This rank corresponds to the grade of lieutenant colonel in many Western militaries. The etymology of the title comes from the Turkish words "bin," meaning thousand, and "başı," meaning head or chief, literally translating to "head of a thousand." Historically, this designation indicated the officer in command of a battalion-sized unit, which traditionally consisted of approximately one thousand soldiers.

Within the Turkish Armed Forces organizational structure, the rank is senior to a major, known as Yüzbaşı, and subordinate to a colonel, known as Albay. Officers holding this rank typically serve as battalion commanders or hold key positions on staff. The rank insignia usually features a straight bar and a star, or a star and a crescent, depending on the specific historical period and branch of service. The title reflects the continuity of military traditions from the Ottoman Empire into the modern republic.
