Every Memorial Day weekend since 1988, Rolling Thunder/Ride for Freedom has been held in Washington, DC, to raise awareness of the Prisoners of War–Missing in Action of all wars.

United States Marine Corps Veteran Staff Sergeant Tim Chambers is known to the world as The Saluting Marine for standing at attention for hours in the middle of the street during Rolling Thunder. In the video below, filmed in 2013, he held the salute for 3-4 hours while standing on concrete, surrounded by the bikers who zipped passed and around him. Despite having a broken wrist, Sgt. Chambers stood strong to perform his powerful act honoring veterans everywhere.

Sgt. Chambers stands with his makeshift memorial — boots, a rifle, flack jacket and Kevlar — displayed proudly at his feet. Over the years, families of fallen soldiers have donated personal items to symbolize their body and spirit.

The courageous feat is never lost on those who take part in Rolling Thunder. Many veterans stop on their bikes to salute to Sgt. Chambers, and thank him in return for upholding such a revered tradition.
