National Guard has authorized 25K troops for the inauguration. That's almost 2 divisions. I'm not concerned at all anymore about the "MAGA army" marching on Washington, if they try, it will be the most one sided battle of all time.
https://www.nationalguard.mil/Resources/Press-Releases/Article/2474123/25k-authorized-50-states-three-territories-and-dc-supporting-presidential-inaug/The Defense Department has agreed to provide up to 25,000 service members to support the Presidential Inauguration National Special Security Event federal law enforcement mission and security preparations, as led by the U.S. Secret Service. The Department of the Army and the National Guard Bureau are working on a sourcing solution now to support this request.
Every state, territory and the District of Columbia will have National Guard men and women supporting the inauguration.
