The viral video shows Polish tanks during a military parade in the country’s capital, and it predates President Trump’s second term.

Some 1,500 U.S. troops have been ordered to the U.S. southern border by President Donald Trump. Here's a glimpse into some of the duties they'll be tasked with when they arrive.

Defense Secretary Pete Hegseth has said that he and President Donald Trump want to “bring the warrior culture back to the Department of Defense.”

The deployment signals the military’s increased role in a much more aggressive immigration policy under the second Trump administration.

This is just the beginning,” one Defense official said about the deployment of active-duty troops to the border with Mexico.

It's unclear who'll take over at the Pentagon and the military services when the top leaders all step down Monday as President-elect Donald Trump is sworn into office.

U.S. officials say the Pentagon will begin deploying as many as 1,500 active duty troops to help secure the southern border in the coming days

Texas Gov. Greg Abbott deployed the troops to the Rio Grande Valley, where he said they'll work side-by-side with U.S. Border Patrol agents to keep migrants from illegally entering the country. Some of those troops left from the U.S. Naval Air Station Joint Reserve Base in Fort Worth Monday morning. The others left from a base in Houston.

That is more than five times the $853 cost of a one-way first class ticket on American Airlines from El Paso, Texas, the departure point for the flight, according to a review of publicly available airfares.

The president has directed the U.S. military to reinforce the border, and the acting secretary of defense on Wednesday announced the Pentagon is sending around 1,500 active duty troops to the country’s southern border, joining 2,500 active duty personnel already there.

The decision to allow law enforcement officers to use facilities at Buckley Space Force Base in Aurora, Colo., plunges the U.S. military deeper into President Trump’s order to secure the southwestern border.
