Members of the United States Military have sworn an oath to uphold and defend the Constitution and protect the American people from all enemies, both foreign and domestic. Soldiers, Airmen, Sailors and Marines have voluntarily accepted the duty to follow all lawful commands and whether Barack Obama & Co. likes it or not, lawful command begins with a lawful Commander-in-Chief. The US Constitution defines what a lawful Commander-in-Chief is, in Article II -- Section I -- Clause V.
