The Somali National Army was made up of the army, navy, air force, and air defense command. The Somali Government's demise led to the de facto dissolution of the national armed forces. Efforts by the Transitional National Government to reestablish a regular armed force have made little progress. Various groups and factions control militias ranging in strength from hundreds to thousands. These militias are in general poorly trained and lightly armed, although some groups possess limited inventories of older armored vehicles and other heavy weapons and small arms are prevalent throughout Somalia.
