The rank system of the Klingon Defense Force bore some resemblance to various Earth ranking systems. A ceremonial sash of varying design and material was worn by commanding Klingon warriors to show rank and status in society. The sash could be made of many materials, most commonly of gold thread or silver metal, such as those worn by Worf and Martok. On the upper section of the sash was an emblem of their House affiliation and various other decorations.

Appendix
Background information
This rank system combined army ranks (general, brigadier, colonel, and possibly captain and lieutenant) with navy terminology (ship captains, commanders, and lieutenants). It was never mentioned if the Klingon Defense Force was a combined service (with colonel being equivalent to ship captain), or if their rank name terminology simply translated oddly compared to Earth systems.
The Klingon Dictionary translates the ranks of cadet (mangHom), ensign (lagh), sergeant (bu'), lieutenant (Sogh), commander (la'; ra'wI), captain (HoD), commodore (totlh), brigadier ('ech), general (Sa'), and admiral ('aj). (pp. 81, 123, 125, 134, 186-189)
