The armed forces swear to defend the Constitution and there is nothing in that document that disallows attacking an ally if ordered to do so.
I don't believe the US military is capable of mutiny beyond unit level and then it's unlikely.

I get the feeling that the Army has too too many obots with stars. Once obambi is out of the White House, providing he isn’t removed violently, then the Army along with everything else will get better.
The Army has led the way with black officers, with nearly double the percentage at times over the past three decades as the other services. Blacks represented 11 percent to 12 percent of all Army officers during that time, compared with 4 percent to 8 percent in the Navy, Air Force and Marines.
