Cossacks
As a unit of the Cossack regiments, it is known from earliest records of the Zaporizhian Sich,

During the Cossack service in the Imperial Russian Armies the typical regiment had five sotnias or squadrons. The term was used in the foot or cavalry Cossack regiments. The unit term was retained until the establishment of Soviet Union in 1922 and termination of the Ukrainian People's Republic and Free Don Cossack Oblast.

Ukrainian National Army divisions
Each sotnia contained three or four chotas (singular chot - literally count; platoons), and each chot was assembled from three riys (singular riy (Ukrainian), literally 'a swarm'; Section or reinforced squad of 10 to 12 men). Every riy was usually equipped with one light machine gun, two or three other special weapons, and at least seven assault rifles.
