The migrant caravan of about 4,000 to 5,000 men, women and children left Mexico City Friday morning to continue their journey to the US via Tijuana, according to several media reports.

The US Justice Department and Department of Homeland Security also posted "an interim final rule" on Friday that migrants who cross the border illegally will not be able to apply for asylum.

President Donald Trump has 5,600 troops to the border ahead of the immigrant caravan. They aren't the only ones there sporting military gear.

And the Washington Post reported that US Border Patrol agents are gearing up with military equipment to prevent the migrants, many of whom are reportedly looking for asylum or a better life, from crossing illegally.

Here are some of the weapons and gear Border Patrol agents are carrying.
