The Day of the Unknown Soldier is observed in Russia every December 3, commemorating all Russian and Soviet soldiers who died in the line of duty, particularly those whose names remain unknown. The day marks the anniversary of the reburial of unknown soldiers' remains from the 1941 Battle of Moscow, which were interred at the Kremlin Wall in the Alexander Garden in 1966. Officially declared a memorial day by the State Duma in 2014, it primarily honors soldiers from the Second World War but also recognizes all Russian soldiers who have died or gone missing in various conflicts. Observances include a wreath-laying ceremony at the Tomb of the Unknown Soldier and commemorative events at monuments dedicated to unknown soldiers across Russia. The Tomb of the Unknown Soldier serves as a significant symbol of remembrance for the sacrifices made by these individuals.
