Washington DC is set to a host a military parade on Saturday to mark the 250th anniversary of the US Army.
The event will also coincide with the 79th birthday of US President Donald Trump, who says the parade will be "like no other".
The event - which the Army has said could cost up to $45 million (£33 million) - will include over 7,000 uniformed soldiers, dozens of tanks and military vehicles, plus marching bands and a fireworks show.
Meanwhile, 'No Kings' protests against the Trump administration are planned in more than 1,500 cities across the US. Organisers are billing the demonstrations as a "nationwide day of defiance" in response to "corruption" in the government.
The military parade is scheduled to begin at around 18:00 local time (23:00 GMT) on Saturday, 14 June and take place around the National Mall which includes the Washington Monument Grounds.
