For the second year in a row, the Army & Air Force Exchange Service (AAFES) will honor Vietnam veterans on National Vietnam War Veterans Day, March 29. In partnership with The United States of America Vietnam War Commemoration, AAFES will give away a free Vietnam Veteran Lapel Pin to everyone who served on active duty during the period from Nov. 1, 1955, to May 15, 1975. Along with the pin giveaway, many exchanges will be conducting ceremonies with local organizations. For more information on the times of the ceremonies at local exchanges, visit the exchange website.
