[3] Listed in military records as an Azerbaijani, Hazi Aslanov was born on 22 January 1910, in Lankaran, Russian Empire (now Azerbaijan).

After his father died in 1923, Aslanov took his place at the Lankaran Brick Factory, while completing Likbez educational courses.

Aslanov was transferred for the second time that year on 12 December to command a platoon in the Vehicle Repair Workshops at Kharkov.

[6] Aslanov was transferred to the Separate Tank Company of the 2nd Caucasian Rifle Division in June 1933, where he commanded a platoon.

[12] In this role, he took part in the Soviet invasion of Poland with the forces advancing into western Ukraine and the breakthrough of the Mannerheim Line during the fighting on the Karelian Isthmus in the Winter War.

When the battalion lost all of its tanks, he was appointed assistant commander of the 10th Motor Rifle Regiment for equipment on 25 August.

The brigade was reorganized as the 55th Separate Tank Regiment in October, reassigned to the 4th Mechanized Corps, and Aslanov, by then a lieutenant colonel, appointed its commander.

In December, he was sent to the Academic Courses for the Improvement of Officers at the Military Academy of the Armored and Mechanized Forces for further training.

After completing the courses, Aslanov returned to command the 35th Guards Tank Brigade in April 1944, having promoted to major general on 13 March.

During the Soviet offensive against the Courland Pocket that began on 23 January, Aslanov's brigade was sent into action on the Pauzeri and Ceļmaļi axis.

Finding impassable swamps and minefields along its march route, the brigade conducted a flanking maneuver to the right and reached Katrīnes manor, where it encountered strong German resistance that stalled its advance.

The second was supposed to be given for the crossing of the Berezina river, under the recommendation of General of the Army Ivan Chernyakhovsky, but he received it posthumously, 46 years later, on 21 June 1991, after a special appeal by Azerbaijani intelligentsia to Mikhail Gorbachev.
