ABC News reported that on May 21, the US military said it was planning to move Abrams tanks from Fort Cavazos base, Texas, to Washington, D.C. to participate in a parade to celebrate the 250th anniversary of the military's founding on June 14.
Transportation of the increased trains to trains is expected in the coming weeks.
In addition to the 28 previously confirmed Abram M1 tanks, the parade in Washington also featured other armored vehicles such as Bradley fighter jets, Strykers, World War II vehicles such as the M4 Sherman tank, Douglas C-47 transport aircraft and P-51 Mustang fighter jets.
In addition, according to US officials, the Cobra and Huey helicopters will also participate, along with 50 other aircraft, 34 horses, 2 muzzles, 1 chariot and 1 dog.
The authorities said heavy equipment will be gathered at West Potomac Park before the parade. The parade will move along Constitution Avenue and end near the White House, where the army's Golden Knights will run down Ellipse.
A parading soldier will solemnly hand the folded flag to President Donald Trump. After the parade, Trump is expected to preside over the constitutional swearing-in ceremony for about 250 new recruits and re-enlisted soldiers.

The America250 organization said that the event will " left behind the 250-year journey of the army, from the American Revolution to future soldiers", with performances of soldiers and vehicles from each period, military music performances and spectacular flights.
The US military plans to spend between $25 million and $45 million on this year's event series, but the final figure could be higher due to many additional costs.
The event was classified by the US Secret Service as a "special national security event," requiring the mobilization of large security forces. However, the security cost has not been specifically announced by the Ministry of Home Security.
The military is also responsible for repairing any damage to roads in Maryland and Washington. To minimize risks, heavy vehicles will be equipped with new rubber chains and sharp, curved sections will be lined with metal plates.
About 6,700 soldiers are expected to arrive in Washington on June 11, temporarily resting on their beds in unused federal buildings such as the Department of Agriculture headquarters.
Mobile bathing areas will be built in security areas. Each person is subsidized with $69/day, two portions of fast food and a hot dinner provided by the contractor.
Many soldiers will participate in the parade in costumes from each period, including the American Revolutionary War uniforms provided by a film production company, to recreate 250 years of military history.
