When you sign up for the military you sign a contract most people don't read there contract either because there to young and eager to join or either the recruiter is rushing them to sign. Within that contract you are to serve 4 yrs active duty and 4 yrs as a non reservist. I served my 4 yrs in the Navy and loved it met my husabnd and had 4 kids I have 4 mths left on my contract as a reservist if they call me back in before the end of July I will have to serve the rest of my contract. What she can do is show that she has nobody to take care of her kids her husband has to be disabled in order for her to get out of the contract.
