Isn't recent suicidal history supposed to disqualify you from joining the military?

I know a woman(who happens to be a neglectful mother) who, not only physically abused her(now- ex-) husband when they were living on base. They are divorced now and have joint custody. CPS got involved last year because the 3 yr. old kept saying: "Mommy grabbed my neck". Because the Mom played nicety-nice with the CPS worker, the case was closed and no parenting cles or anthing else was ordered. This is a Mom who binge-drank vodka into the 2nd trimester of her pregnancy(while living on base with her soldier husband), and hid the entire pregnancy from a loving spouse and told NO ONE she was pregnant, including her mother and her identical twin with whom she is close. She sought no medical attention or alternative care although her first baby was an emergency C-section. Nobody knew she was pregnant until she went into labor. Not only that she had a suicide attempt in 2008, and now she is in the process of working with a recruiter to join the army? Her mother had to take her to the hospital to get her stomach pumped but she had no psychiatric intervention that followed. She is also extremely selfish, and a clearly unfit mother.
