Military restricts domestic travel, visits to Pentagon

"This restriction will halt all domestic travel, including Permanent Change of Station, and Temporary Duty," the Pentagon added.

Also, all civilian hiring at U.S. military installations is being put on hold.

All of these new restrictions take effect March 16, and are currently set to last through May 11.

As for the Pentagon, the giant military office facility just across the Potomac River from Washington, D.C., operations there will also change.

"All unofficial visits are suspended, to include personal guests and friends of DOD personnel and contractors," the new guidance states. "All large gatherings, such as retirement and promotion ceremonies, shall cease."

Like the U.S. Capitol, Supreme Court, Smithsonian Museums, and more, the Pentagon is also ending public tours.

Also, the military has suspended any visits by international allies to the Pentagon.

Despite the precautions, Pentagon officials have said the threat to service members from the Coronavirus remains low.
