Posse Comitatus doesn’t apply to the USMC?

[EBH]

Navy and Marines.
The Posse Comitatus Act proscribes use of the Army or the Air Force to execute the law. It says nothing about the Navy, the Marine Corps, the Coast Guard, or the National Guard. The courts have generally held that the Posse Comitatus Act by itself does not apply to the Navy or the Marine Corps.Nov 20, 2017
