It's in the contract. This lawsuit is pure liberal crappola...
Yes. Here's what my Dad's WWII "Terms of Enlistment" says about length of service:
"Enlistment for the duration of the war or other emergency, plus 6 months, subject to the discretion of the President or otherwise according to law."
Since the Pres is the Commander-in-Chief, I assume that the "subject to the discretion of the President" phrase would still be in ALL service contracts...
