On the same day President Donald Trump told reporter that the United States could send up to 15,000 military personnel to the border Peterson Air Force Base announced it was providing support. Fort Carson is also providing support according to Peterson officials.

According to Peterson Air Force Base the Secretary of Defense approved the following forces and support in response to the Department of Homeland Security's request:

-Military planning teams to coordinate operations, engineering, medical, and logistic support

-Helicopter companies to support the movement of CBP tactical personnel

-Engineer battalions to erect temporary vehicle barriers and fencing

Deployable medical units to triage, treat and prepare for commercial transport of patients

-Temporary housing to support CBP and military personnel

-Light towers, barrier material, barbed and concertina wire, as well as cases of meals ready-to-eat

President Trump told reporters at the White House on Wednesday that "we'll go up to anywhere between 10 and 15,000 military personnel on top of Border Patrol, ICE and everybody else at the border."

At this time, it isn't clear how many personnel from Fort Carson or Peterson will be sent to the border.

The president says the move would be aimed at preventing the entry of a caravan of migrants traveling from Central America. The caravan is still nearly 1,000 miles from the border.

President Trump says that the U.S. was "going to be prepared" and that the migrants are "not coming into our country."

Currently there are 2,100 National Guard helping at the border. The Pentagon says an additional 5,200 active-duty troops could join them.

The following military units have been identified to deploy to the southwest border in support of this operation. The number of troops deployed will change each day as military forces flow into the operating area, but the initial estimate is that the Department of Defense will have more than 7,000 troops supporting DHS across California, Arizona and Texas.
