Tank Crewman’s Day is observed in Armenia every October 8 to commemorate the formation of the country's tank forces, which was officially established in 1992. This professional observance honors both active and retired members of tank crews in the Armenian Armed Forces. The day has its origins in the Soviet era, where a similar holiday was celebrated annually on the second Sunday of September. Following Armenia's independence, the date was changed to October 8 to mark the establishment of the Armenian tank battalions. On this day, individuals who have served as tank crew members receive congratulations and gratitude for their contributions to national defense. The Armenian Ground Forces currently operate three independent tank battalions, utilizing tanks produced in the Soviet Union and Russia, including T-90 and T-72 main battle tanks.
