Carpathian Sich (also the Carpathian Sich National Defence Organization) was a military organization in Carpatho-Ukraine in 1938–9, formed in November 1938 from units of the Ukrainian National Defence. The organization’s headquarters were in Khust, and there were 10 individual district commands with subordinate local sections, which conducted military and political training involving several thousand men. Five permanent garrisons conducted regular military training, and a number of the Sich soldiers served in the local police force and with the border guards. The Carpathian Sich adopted uniforms and ranks modelled on those of military formations in Ukraine during the struggle for independence (1917–20). It was also involved in cultural and educational work among the local population.
