The Army on Wednesday started loading up some of the tanks that will take to the streets of the nation's capital during the 250th anniversary celebration of the service next month, which will feature hundreds of military vehicles and aircraft and thousands of soldiers. 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. AP Video shot by Jim Vertuno
