DALLAS -- The Army & Air Force Exchange Service is honoring Vietnam veterans with a 53-foot rolling billboard. For the second year in a row, the Exchange created a custom truck design that appears on three of the Department of Defense retailer's tractor-trailers that deliver merchandise across the United States.

The trucks also deliver a message to Vietnam veterans: "On behalf of a grateful nation, thank you for your service and sacrifice."

Alongside the message is an image from the National Archives of a young warfighter, and in the background names carved into the Vietnam Veterans Memorial Wall can be seen.

The Exchange created the custom truck design to express gratitude to Vietnam veterans. As a proud partner with the United States of America Vietnam War Commemoration, the Exchange plans and conducts events to recognize the service, valor and sacrifice of Vietnam veterans and their families.

"It's so important we always remember these veterans' service," said Exchange Director/CEO Tom Shull, who served in the Army during the Vietnam era. "The Exchange is grateful for our Vietnam veterans and for the opportunity to thank them with this special truck design."

Maj. Gen. (retired) James Jackson, Commemoration director, praised the design's message.

"The Exchange's truck design is a rolling tribute to Vietnam veterans," Jackson said. "Every time these trucks are on the road, they are supporting the Commemoration's mission of honoring our brave Vietnam veterans and their families."

Exchange Facilities Management Office foreman and Vietnam-era veteran Eldon Ashley watched the new truck design being applied at the Exchange's Waco Distribution Center in Waco, Texas.

"I think it's great because it lets everyone who served know they were appreciated," said Ashley, who served in the Air Force on active duty for four years and in the Reserves for 21 years. "That's all they want, just to be appreciated."

Ashley said he likes that the truck communicates who the Exchange is serving -- the men and women who have worn the nation's uniforms.

"When I went overseas, that was the one thing we looked forward to: seeing the Exchange there," Ashley said. "It felt like home when you walked in."

The trucks also highlight that all honorably discharged veterans can now shop the Exchange tax-free for life at ShopMyExchange.com. Since the benefit launched in November 2017, veterans shopping the Exchange online have saved nearly $5 million in sales tax.

The three trucks will transport goods from the Exchange's continental U.S. distribution centers to service members throughout the country. The Dayton, Ohio truck terminal; Dan Daniel Distribution Center in Newport News, Va.; and the Waco Distribution Center will each have a truck in service on their standard delivery routes.

The United States of America Vietnam War Commemoration is a program administered by the Office of the Secretary of Defense to commemorate the 50th anniversary of the Vietnam War. The Commemoration was authorized by Congress, established under the secretary of Defense and launched by the president in 2012. It will continue through Veterans Day 2025.
