Millions of demonstrators mobilized around the country as a smaller, subdued crowd gathered to witness the display of grandeur and might in the nation’s muggy capital.

The procession featured more than 6,000 soldiers, 128 Army tanks, aircraft flyovers, military bands, even robot dogs. Troops wore uniforms representing the Army’s history, including outfits from the Revolutionary War, Civil War, World War II, the Vietnam War and the Global War on Terror.
