The Armenian army's history is described to have gone through three stages of development. It entered the first stage in February 1988, from the beginning of the Nagorno-Karabakh conflict, when Armenian militias were formed to combat Azerbaijani units in Artsakh. On 20 September 1990, the first military unit was created, the Yerevan Special Regiment, with the first oath being held in the Republican Assembly Point and was attended by the first President of Armenia Levon Ter-Petrosyan, Prime Minister Vazgen Manukyan, Vazgen Sargsyan. The second phase of the development of the army began in 1992, several months after Armenia declared its independence from the Soviet Union. Ter-Grigoryants and civilian officials in the Armenian Ministry of Defense, including Vazgen Manukyan and Vazgen Sargsyan, sought to establish a "small, well-balanced, combat-ready defense force." The third phase began after the end of the war and continues to today.
