President Trump is hosting a parade celebrating the 250th anniversary of the U.S. Army today, bringing tanks and soldiers to the streets of Washington, D.C., for the capital's first major military parade in more than three decades.

Millions of American soldiers have marched in military parades since the Civil War, which marked the tradition as a fundamental ritual of American unity.

The military parade to mark the Army’s 250th anniversary and its convergence with President Donald Trump’s 79th birthday are combining to create a peacetime outlier in U.S. history. Yet it still reflects global traditions that serve a range of political and cultural purposes.

President Donald Trump praised the United States Army as the “greatest, fiercest and bravest fighting force” at the conclusion of a grand display of military might in the nation’s capital Saturday as the Army celebrated its 250th birthday with a parade.

Washington, D.C. is gearing up for one of the largest military parades in recent history as the U.S. Army marks its 250th anniversary this Saturday.
