A parade in Washington, D.C., commemorating the 250th anniversary of the armed services and coinciding with the birthday of President Donald Trump, kicked off Saturday with a grand showing of the military's power throughout the National Mall.

Eighty-four military vehicles, including 28 Abrams tanks, 6,700 marching soldiers and other military presentations, were all on tap for the celebration, which also happened to fall on Trump's 79th birthday.

ABC News observed some people in the crowd wearing MAGA hats and others burst into singing "Happy Birthday," as the parade was about to begin. The parade started a half hour early -- at 6 p.m. -- due to weather.
