June 7 (UPI) -- The U.S. Army celebrates its 250th birthday on June 14th in the nation's capital, which coincides with President Donald Trump's 79th birthday, and will be marked by a parade that may include tanks, rocket launchers and more than 100 military vehicles.

With the two birthdays occurring on the same day, the previously scheduled parade that was intended as a relatively small event at the National Mall in Washington, D.C., has grown in size and cost.

Up to 300 soldiers and civilians, the U.S. Army Band and four cannons were initially slated to honor the Army's 250th birthday, with seating available for 120 attendees, The Washington Post reported.

U.S. Army leaders last year sought a permit for the event, but Trump's election victory has changed its scope, while doubling as an unofficial celebration of the president's birthday.
