Troops from all the services will take part in the southern border buildup, either on duty to back up U.S. Customs and Border Patrol (CBP) in the border states or serving as base support in other areas, according to U.S. Northern Command.
Base Support Installations chosen for Operation Faithful Patriot include Davis-Monthan Air Force Base and Fort Huachuca in Arizona; and Marine Corps Air Station Miramar, Marine Corps Base Camp Pendleton; Naval Air Facility El Centro, Naval Base Coronado, Naval Base San Diego, and Naval Base Point Loma in California.
In Texas, the Base Support Installations will be Fort Bliss, Lackland Air Force Base, Naval Air Station Corpus Christi, Naval Operations Support Center Harlingen, and Naval Air Station Kingsville, NORTHCOM said in a statement.
Those bases will serve troops actually going to the border, who will be strictly limited to supporting CBP and will not have law enforcement authorities of detention or arrest in the event of the arrival of the "caravan" of migrants and political asylum seekers now heading north through Mexico.
The NORTHCOM statement also identified units that have already been notified to deploy in support of CBP, but said the actual number of troops on the border will change daily with the flow of units.
NORTHCOM said the initial estimate is that about 7,000 total active-duty troops will deploy, in addition to the 2,000 National Guard troops who have been on the border since April, although President Donald Trump said earlier at the White House that the number of troops could rise to as many as 15,000.

At a welcoming ceremony for South Korean officials at the Pentagon on Wednesday, Defense Secretary Jim Mattis said the deployments are not unusual and should not be seen as other than routine military support occasionally provided for other federal agencies, according to a released pool report.
He also rejected the charge that the border buildup is a "political stunt" by Trump to boost support for Republicans in the midterm elections.
"The support that we provide to the Secretary for Homeland Security is practical support based on the request from the Commissioner of Customs and Border police, so we don't do stunts in this department," Mattis said.
He likened Operation Faithful Patriot to the military assistance provided after hurricanes.
"We do this following storms, we do this in support of the Department of Homeland Security. This is a different aspect of it, but that's what we are doing," he said.
Air Force Gen. Terrence O'Shaughnessy, commander of NORTHCOM, gave the first indication that all services would be involved at the border at a gaggle with Pentagon reporters Tuesday.
He said that "every airman, soldier, sailor, and Marine going there" would be fully trained for the mission at the border.
Citing an internal document, The Washington Post reported this week that the deployed force will include a special purpose Marine air-ground task force, among other elements.
However, a Marine Corps spokeswoman said earlier Wednesday that no specific Marine units had yet been tasked by NORTHCOM for the operation.
