President pulls troops out of Syria, places military on US border

The Posse Comitatus Act is a United States federal law signed on June 18, 1878 by President Rutherford B. Hayes. The purpose of the act – in concert with the Insurrection Act of 1807 – is to limit the powers of the federal government in using federal military personnel to enforce domestic policies within the United States. It was passed as an amendment to an army appropriation bill following the end of Reconstruction, and was subsequently updated in 1956 and 1981........................The Posse Comitatus Act of 1878 was passed to prevent US military personnel from acting as law enforcement agents on US soil. This was common practice before 1878, particularly in areas of the West where the US military was often the only law enforcement to be found. Soldiers often enforced civilian laws whenever it was necessary. The Posse Comitatus Act banned this practice, and the Act still remains in effect. The text (18 U.S.C. Section 1385), reads: "Whoever, except in cases and under circumstances expressly authorized by the Constitution or Act of Congress, willfully uses any part of the Army or the Air Force as a posse comitatus or otherwise to execute the laws shall be fined under this title or imprisoned not more than two years, or both."

I thought that there could be no standing U.S. soldiers on domstic soil unless stationed on mlitary bases.

However each state's Naional Guard would be able to assemble at the borders of their respctive states.

If I'm wrong about this please let me know.
