U.S. Army tanks and other equipment arrived by train to the nation's capital to take part in military parade for the service's 250th birthday celebration on June 14, which will feature hundreds of military vehicles and aircraft and thousands of soldiers.

Among the equipment arriving Saturday from Fort Cavazos, Texas, are army tanks, Bradley fighting vehicles, Paladin howitzers, and other equipment.

The event has grown extensively in scope and size since Army planners started working on a festival two years ago to mark the day and have now added a military parade — which President Donald Trump had unsuccessfully tried to do during his first term.

The Army’s anniversary celebration is set for June 14, which also happens to be Trump’s birthday.

It will include concerts, fireworks, NFL players, fitness competitions and displays all over the National Mall for daylong festivities. The Army expects as many as 200,000 people could attend and that putting on the celebration will cost an estimated $25 million to $45 million.

On the day of the parade, tanks as well as 28 tracked Bradley Fighting Vehicles, 28 wheeled Stryker combat vehicles, four tracked M-109 Paladin self-propelled howitzers and other towed artillery will maneuver to the start of the parade route just off the National Mall.

They will travel toward the White House, driving over thick metal plating to protect the streets at some parade points where the vehicles make a sharp turn.

The Army said it’s also planning some additional asphalt work and putting new rubber padding on the tanks’ metal tracks to try to minimize street damage.
