Formations. Drills and maneuvers. Music and ceremony. President Donald Trump wanted a military parade that bests what he once witnessed in France. But raw displays of military power are more common to ones in Russia, China and North Korea, where such parades carry added meanings. Up to 7,500 troops, 120 vehicles and 50 aircraft will take to the streets and skies of Washington, D.C. on June 14 to celebrate the U.S. Army's 250th anniversary. The event coincides with Trump's 79th birthday. It also marks a rare example of an official military parade taking place inside the United States.
