When I first read this thread, I could already hear what my mother would say. I'm a military brat (although my dad got out when I was young and I don't remember much of it). If you enlist, you are making a commitment. Whether during peace time or when our country is at war, you have a commitment to do your job and do what you signed up for. It's not like someone, especiallly now, doesn't know what they're getting into. When I was born, we were stationed overseas. We weren't at war, but my mom and I had to both have passports (I'm only a few days old in my picture) so if something happened and my dad was sent to war, my mom and I would both be sent home immediately. They had some friends who were parents and both in the military. Those parents purposely made friends with the non-military spouses so they would have someone to watch their kids if need be. Being overseas, no one had family there to help out, the other members of the military and their families WERE a family. If a person does not want to have to leave their child(ren), they should either not be in the military, or not have kids. There are too many preventitive measures these days for some to "accidently" get pregnant. Yes, it does happen, on occassion. However, as STEADFAST mentioned, this woman could have left the military when she realized she was pregnant. Also, knowing that you're going to be deployed, don't you think you would talk with the person who is supposed to watch your child when you leave? This woman should have known long ago that it would be too much for the grandmother to watch the child.
To me it's the same thing as any other job. If you don't complete your REQUIRED job duties, which you are already aware of, you'll be fired for being in noncompliance. Doesn't matter if your children are sick for 3 weeks, find an alternative care giver. You cannot just refuse to do your job without consequences. If she wanted a child, she shouldn't have enlisted.
I know it sounds like I'm being harsh, but these issues, along with others, are what I discussed with my parents before I graduated high school. I was contemplating going into the military. I chose not to for a number of reasons. Bottom line, this woman CHOSE to enlist and CHOSE to have a child and CHOSE to apparently not discuss the "plan" with her mother. Her CHOICES have led to this situation, there is nothing in this situation that was beyond her control.
