Ukrainian People's Army

The Ukrainian People's Army (Ukrainian: Армія Української Народної Республіки, romanized: Armiia Ukrainskoi Narodnoi Respubliky), also known as the Ukrainian National Army (UNA) or by the derogatory term Petliurivtsi (Ukrainian: Петлюрівці, lit. '"Petliura's people"'), was the army of the Ukrainian People's Republic (1917–1921). They were often quickly reorganized and Ukrainized units of the former Imperial Russian Army and newly formed volunteer detachments that later joined the national armed forces. The army lacked a certain degree of uniformity, adequate leadership to keep discipline and morale. Unlike the Ukrainian Galician Army, the Ukrainian People's Army did not manage to evolve a solid organizational structure, and consisted mostly of volunteer units, not regulars.
