Which military service celebrated its 250th anniversary with a 2025 parade connected to America250?

The military service celebrated with the 2025 parade connected to America250 was the United States Army.

The United States Army was established on June 14, 1775, when the Second Continental Congress created a unified Continental Army during the American Revolutionary War. Its 250th anniversary therefore came one year before the nation’s semiquincentennial in 2026.

The parade took place on June 14, 2025, in the Washington, D.C., area. Its route ran from the Pentagon in Arlington, Virginia, toward the National Mall. The event included soldiers, military vehicles, aircraft, horses, musical performances, and historical elements.

The date also coincided with Flag Day, which commemorates the adoption of the Stars and Stripes on June 14, 1777. The Army celebration is distinct from America250’s national anniversary because it honors the founding of one military service rather than the Declaration of Independence.
