Mongol Military: Hierarchy

There were no ranks in the Mongol Empire in the modern sense of a hierarchy of titles, although the army was organized into a hierarchical command. The organization of the Mongol army was based on the decimal system, much like that of the Achaemenid Empire of Persia. The army was built upon a squad of ten (aravt) led by an appointed chief. Ten of these would then compose a company of a hundred (zuut), also led by an appointed chief. The next unit was a regiment of a thousand (myangat) led by an appointed noyan. The largest organic unit was a ten thousand man unit (tumen) also led by an appointed noyan. The Mongalisen is what we would call General of the Army.
