Mothers, the military and ism: men what's your POV.?

i answered a question earlier in the parenting forum from a young mother who wanted to join the navy and it made me think about something. isn't it ist in a way that mothers to be have the option to get out of the military but fathers to be do not? i wondered that quite a bit actually when i was married to an airman. this young lady was concerned about college money as are a lot of enlistees which i understand. i suggested she apply for student loans. i have a friend who did get out of the air force when she had her baby and i see why she did that. so i guess i have two questions. one, should mothers/parents join the military? two, should women be given the option to get out of the military when they are pregnant?
