The Trump administration will send more than 800 troops to the U.S.-Mexico border ahead of the illegal invasion by the orchestrated group of migrants who rejected Mexico’s offer for amnesty.

Most of the troops are active-duty Army soldiers who specialize in logistics and engineering. Others are medical staff and an Air Force contingent to assist with aerial evacuations.

They will join more than 2,000 National Guard troops already deployed to the region in April.

“You’re going to see a very secure border. You just watch,” President Trump has been telling supporters at political rallies this week. “The military is ready. They’re all set.”

National Guard troops are not involved in patrolling or arresting illegal immigrants or smugglers, they provide logistic and communication and office support to enable Border Patrol to stay in the field.

Mexican officials estimate the caravan totals roughly 3,630 people mostly from Honduras. Among them MS-13 gang members.

“This caravan deal presents an opportunity for incredible criminal activity,” said Chris Farrell, Judicial Watch’s director of investigations. Farrell was in Central America tracking the caravan and saw men wearing MS tattoos.

He also saw what Border Patrol agents call, “special interest aliens,” people from countries not normally from those that send economic migrants.

“President Trump’s use of military force to protect America’s southern border is mandated by the commander in chief’s oath of office and constitutional duties,” said Rep. Mo Brooks, Alabama Republican.
