He was born in Stepanakert in 1965 to an Armenian family. Mnatsakanyan began his military service in 1983 when he moved to the Belarusian SSR to work in the Soviet Army's Belarusian Military District. In 1989, he graduated with honors from the Karl Marx Institute of Polytechnic. During the period after the Soviet Union fell apart when Armenia began to build up its military, Mnatsakanyan served in artillery units in the Artsakh Defense Army and the Armed Forces of Armenia. He graduated from the Military Academy of the General Staff of the Armed Forces of Russia in 2005, which resulted in him returning to Artsakh later that year to become the deputy commander of the defense army.
He was appointed by President Bako Sahakyan in 2015 as defense minister, a position he served in for just over 3 years before he was replaced in December 2018. He was then appointed to the post of Director of the State Service of Emergency Situations. He was dismissed in June 2019 and was made Chief of Artskah Police. He is currently married and has three sons.
