 Beside the federal Yugoslav People's Army, each constituent republic of the former SFR Yugoslavia had its own "Territorial Defense Forces".The Non-Aligned Yugoslavia was concerned about an eventual aggression from any of the superpowers, especially by the Warsaw Pact after the Prague Spring, so the "Territorial Defense Forces" were formed as an integral part of the total war military doctrine called "Total National Defense".Those forces corresponded to military reserve forces, paramilitary or militia, the latter, in the military meaning of the term (like military formation).
