Çavuş
Çavuş, also anglicized Chaush and Chiaus (from / , "messenger"), Arabic 'shawish, شاويش', (from Old Turkic "Çabuş" or "Çawuş", "person who gives order, person who yells") was an Ottoman title used for two separate soldier professions, both acting as messengers although differing in levels. It was a rank below "agha" and "kethüda" (from Persian, kad-khuda, "magistrate"), in units such as the Janissaries and Sipahi, and was also a term for members of the specialized unit of "çavuşān" (, also "çavuşiyye", "çavuş(an)-i divan(i)") consisting of combined cavalry and infantry serving the Imperial Council (as in Ottoman Egypt). The leaders of the council 's "çavuş" were titled "çavuşbaşı" / (or "başçavuş" / ). The çavuşbaşı was an assistant (or deputy) to the Grand Vizier, dealing with security matters, accompanying ambassadors visiting the Grand Vizier, and also carried out the first examination of petitions submitted to the Council, and led council meetings when the Grand Vizier was not present. The title has its origin in Uyghur use, where it was the title of ambassadors, and then entered Seljuq use for Byzantine imperial messengers, and Persian and Arabic use for various court attendants. The word gave rise to surnames, such as Çavuş (Turkish), Çavuşoğlu (Turkish), Čaušević (Serbo-Croatian ), Čaušić (Serbo-Croatian), Baščaušević (Serbo-Croatian), Çaushaj (Albanian), Ceaușu (Romanian), Ceaușescu (Romanian), Τσαούσης (Tsaousis in Greek), and others. It is also the stem of place names, such as Çavuş (in Turkey), Çavuşlu (in Turkey), Çavuşlar (in Turkey), Çavuşköy (in Turkey), Çavuşbayırı (in Turkey), Čauševac (in Bosnia), Čauševići (in Bosnia and Serbia), Čaušev Do (in Bosnia), Čauševina (in Bosnia), Čaušlije (in Bosnia), Čaušlija (in Macedonia), Chavusy (in Belarus), Çaushi (in Albania), and others. In the past in former Yugoslavia, the word "čauš" was also sometimes applied to the wedding-planner. Modern Turkish military usage. In the modern Turkish Armed Forces, the  rank of "Çavuş" is equivalent of "sergeant" (and NATO OR-5 rank), and ranks above the rank of "Onbaşı" ("corporal"). The insignia is two inverted chevrons, in red or camouflage pattern, depending on the dress.
