According to Ugo Cavallero, most of the insurgent forces were led by former officers of the Kingdom of Yugoslavia until the end of October 1941. During preparation for uprising in Montenegro, the Communist Party of Yugoslavia came in touch with active and reserve officers of the former Royal Yugoslav Army, because there were many young people in the ranks of the insurgents who did not know how to handle a firearm. Thus Lašić became a member of the Partisan Military Committee for Andrijevica. When Axis Albanian units started to concentrate toward the liberated territory, Lašić was co-opted in the District Military Command. Lašić often spoke out against the communist leadership of the uprising. The leadership itself didn't have illusions of prolonged cooperation with Lašić, but were trying not to aggravate relations with him until the Partisans liberated Plav and Gusinje. When the Royal Italian Army began its offensive against the Partisans, Lašić on 4 August abandoned his position in partisan District Military Command and joined the anti-communist group of Ljubo Vuksanović, who opposed further struggle against Axis occupation. After Partisan withdrawal from Berane and Andrijevica in early August, Lašić was a member of the delegation sent to meet the Royal Italian Army. On 5 September Lašić in Lijeva Rijeka gathered people and called for combat against communist rebels.
