To thank Vietnam veterans for their sacrifices, the Army and Air Force Exchange Service is debuting a new truck design, part of the Department of Defense retailer’s efforts alongside the United States of America Vietnam War Commemoration to honor veterans during the 50th anniversary of the war. “The Exchange is privileged to have the opportunity to recognize Vietnam veterans through our fleet,” said Exchange Director/CEO Tom Shull, who served in the Army during the Vietnam era. “These trucks will serve as rolling billboards, expressing gratitude for all who served during this era.”
