Mongolian Military Day, observed in Mongolia every March 18, celebrates the country's armed forces and serves as an informal male equivalent to International Women’s Day. The holiday commemorates the anniversary of the Mongolian Armed Forces, which trace their origins back to the Mongol Empire and are closely linked to the Mongolian Revolution of 1921. On this day, Mongolian troops led by Damdin Sükhbaatar, supported by the Soviet Red Army, attacked a Chinese garrison, marking a significant event in Mongolia's history. Celebrations typically include a wreath-laying ceremony and a gun salute at Sükhbaatar Square in Ulaanbaatar, along with various award ceremonies, military tattoos, concerts, and other events. Established in 1946, Mongolian Military Day honors all Mongolian men, many of whom have served in the military due to mandatory conscription.
