The Leon Sedov Brigade (Arabic: لواء ليون سيدوف) was a Syrian Third camp Trotskyist militant group in the area of Aleppo. Although its founders were Argentinian foreign fighters, the overwhelming majority of its members were local industrial workers and, due to its stance against foreign involvement in the Syrian civil war, was solely funded by members' wages and ran by officers elected by them. It is named for Leon Sedov, the first son of Leon Trotsky. It is the military wing of the International Leninist Trotskyist Fraction and thus shares its basic positions of opposing both Salafi jihadist groups (including Hay'at Tahrir al-Sham and the Islamic State) and pro-Western liberal Free Syrian Army factions as counter-revolutionary, and all foreign involvement in the Syrian civil war (including the Turkish-backed Free Syrian Army and the US-led coalition-backed Syrian Democratic Forces) as imperialist.^[3]
