Which U.S. military branch marked its own 250th anniversary during the America250 buildup in 2025?

The United States Army marked its own 250th anniversary during the America250 buildup in 2025.

The Army’s 250th Birthday Grand Military Parade and Celebration took place on June 14, 2025, in Arlington, Virginia, and Washington, D.C. It commemorated the Army’s establishment on June 14, 1775, making the branch older than the Declaration of Independence adopted the following year.

The parade was described as part of the celebrations leading toward the United States Semiquincentennial. It also coincided with Flag Day and President Donald Trump’s birthday, making the event notable for several overlapping reasons.

The Army is often confused with the U.S. military as a whole. The event marked the anniversary of one branch, not the founding of all six armed-forces branches. The Army’s date comes from the Continental Congress’s creation of the Continental Army in 1775.
