The U.S. Army is planning a historic parade through the streets of Washington, D.C., on June 14 that will coincide with and be part of the Army’s long-planned 250th celebration.

The parade will involve some 6,600 soldiers, tanks and infantry vehicles, helicopter flyovers and parachute jumps, according to several people familiar with the planning effort, and will also occur on Donald Trump’s 79th birthday.

The timing and White House involvement in planning efforts have stoked speculation that Trump is using the Army’s birthday as an excuse to get the kind of grand military parade he wanted during his first term in office. That event was scrapped after estimates topped $90 million.
