Born on 21 December 1917 into a peasant family in the Georgian village of Mathondzhi, he attended a high school in Tbilisi. Afterwards Adamia joined the Soviet Navy in 1938 and served in coastal defenses as anti-aircraft gunner. In 1940 he graduated from the Odessa Military Naval School and became platoon commander.
Serving at the front lines since 1941, he decided to become active as sharpshooter by own will and in 1942 due to his impressive efficiency with the rifle was given instructor status and ordered to train more than 70 marines of the Soviet 7th Marine Brigade stationed in Sevastopol in sniper warfare. He had mastered sharpshooting by himself and was engaged in the most dangerous areas of the district. Within two months he had all candidates prepared for combat. Up until becoming platoon commander Adamia was credited with killing more than 200 enemy soldiers and knocking out two enemy tanks. On 21 June 1942, facing encirclement by German troops, the petty officer led a small 11 man strong sniper detachment to break the ring in which they succeeded, killing more than 100 enemy soldiers. The fierce battle went on even out of the encirclement.
Sniper tactics
From December 1941 Adamiya became pioneer of the Sevastopol sniper movement. In the beginning his primary targets were enplaced positions but he soon moved on for active hunts using both the Simonov PTRS-41anti material rifle and the Mosin–Nagantsniper rifle to take out soft and lightly armored targets. To one of the Soviet army news papers he said: Adamiya went on describing how he started to learn calculation of range, observing and slowly mastering the effects of humidity and other aspects of shooting from long distance. One day he took point on a tree covered high ground and observed German troops moving around their entrenched positions to keep themselves warm. He was able to take out six targets over a range of 600 m with his Mosin–Nagant and improved his rate each day after, going out for several days with only a loaf of bread and little water. Adamiya tried to determine when enemy forces would concentrate on a specific position for example by observing if improvised latrines or similar points were built. Yevgeniy Ivanovich Zhidilov wrote in his book "We defended Sevastopol":
Death
Adamia met his fate a day before Sevastopol fell to Axis forces on 4 July 1942. He was one of the 60,000 Soviet defenders who were not evacuated. On 3 July Adamia was killed in the area of Gasfort, Kamysheva Bay. He was buried in Sevastopol along with 86 soldiers of the 7th Marine Brigade.
