Thousands of Americans flocked to downtown D.C. in "Make America Great Again" hats and patriotic gear displaying Old Glory despite the balmy weather and thunderstorms brewing.

The military parade is slated to start at 6:30 p.m. ET tonight and run until about 7:45 or 8 p.m., according to schedules posted by the Army and the city of Washington. The Army will conclude the event with fireworks on the National Mall around 9:45 p.

For its 250th birthday, the Army put on the largest show of military might in the capital in more than three decades.
