A tug (Mongolian: туг [tʰʊɡ], Turkish: tuğ, Ottoman Turkish: طوغ ṭuġ or توغ tuġ, Old Turkic: 𐱃𐰆𐰍, romanized: tuğ) or sulde (Mongolian: сүлд, Tibetan: བ་དན) is a pole with circularly arranged horse or yak tail hairs of varying colors arranged at the top. It was historically flown by Turkic tribes such as Tuğluğ Confederation[2] and also during the period of the Mongol Empire, and later used in derived Turco-Mongol khanates. It was also used by the Ottoman Empire, a state which was founded by Turkic Oghuz tribes.[3] In the 17th century, it was also adopted by Slavic cavalry (cossacks, haidamaka), under the name bunchuk (Ukrainian: бунчук, Polish: buńczuk) which is the reflection of the original Turkic word boncuk. It is still used by some units of the Polish military.[4]
