[1] He was awarded the Honoured Master of Sports of the USSR title in 1976.

Born in Leninakan, Armenian SSR (now Gyumri, Armenia), a city famous for its world class weightlifters,[2] Militosyan took up weightlifting in 1964 under the guidance of Hakob Faradzhyana and joined the Soviet national team in 1975.

Militosyan set four world records during his career, all in the clean and jerk.

In 1980, Militosyan completed his weightlifting career after he was not selected to join the Soviet team at the 1980 Summer Olympics.

Ironically, Vardan was the first Soviet-Armenian to win an Olympic medal in weightlifting, and Israel was the last.
