Balli Kombëtar
During World War II Skënder Muço joined the ranks of Balli Kombëtar, one of the most important resistance organizations in Albania. At the end of November 1942, along with Hysni Lepenica, a former gendarmerie officer from Gjirokastër, he founded the first battalion of Balli Kombëtar in Vlorë named "Shqiponja" (). Muço also became head of Balli Kombëtar in the Vlorë region and a member of the organization's council. As commanders of "Shqiponja" Muço and Lepenica confronted many times the Italian and later Germans troops. One of the most important of those battles was the battle of Gjorm, in which Balli Kombëtar inflicted heavy losses on the Italian army.
