In the
Polish army (from the 15th century to the mid-20th century) a
rotmistrz commanded a formation called a
rota. However, a
rotmistrz of
hussars was a commander of between 100 and 180 hussars, with a lieutenant of hussars as his second-in-command. The Lithuanian term was
rotmistras. In earlier times, the
rotmistrz served as the commander of an
infantry or
cavalry company, though sometimes he would temporarily be assigned field rank tasks e.g. commanding an entire
regiment or even a larger formation. In the cavalry, the rank continued until 1945 as a company level title. Applied to the commander of a
troop, it was equivalent of a modern-day
captain. The rank was also adopted by
Russian
New Regiments as
rotmistr (ротмистр) and later formalized in
Table of Ranks as the cavalry post; until 1798, and between 1883 and 1918, a lower-ranking
shtabs-rotmistr (штабс-ротмистр) also existed, representing the ranks of Senior Captain and Junior Captain in the Russian Imperial Guards Cavalry, Army Cavalry, Gendarmerie and Border Guards by 1914. In British and Commonwealth military forces, a Riding Master is not a rank. In the
Household Cavalry Regiment a suitable
Warrant Officer with the rank of
Riding Instructors is appointed Riding Master. The duration of this appointment is determined by the commanding Lieutenant-Colonel and, once appointed, the Riding Master is the person in the lead of training of recruits and horses of the
Household Cavalry Regiment. == NATO code ==
