He was instrumental in David Bek's victories over the forces of Safavid Iran and the Ottoman Empire in Armenia's Syunik region. Their main headquarters were at the fortress of Halidzor which also served as the administrative center for Syunik. Mkhitar served as chief aide to David Bek and later his successor after his death in 1728.
