Firmenich

Mario Firmenich was the leader of the Montoneros, a significant leftist Peronist guerrilla group in Argentina during the 1970s. Under his leadership, the organization conducted a series of high-profile attacks against the military and government officials, including the attack on the Regimiento de Infantería de Monte 29 in Formosa. Firmenich's ideology and strategic decisions were pivotal in shaping the group's trajectory as they sought to challenge the Argentine state through armed struggle.
