Yugoslavia organized the Yugoslav People's Army (Jugoslavenska narodna armija, or JNA) from the Partisan movement and became the fourth strongest army in Europe at the time. The State Security Administration (Uprava drzavne bezbednosti/sigurnosti/varnosti, UDBA) was also formed as the new secret police, along with a security agency, the Department of People's Security (Organ Zastite Naroda (Armije), OZNA).
