The US Army (and the Reserve Component of each branch of the US Military) actually has a mechanism in place to prevent the problem Leslie faces in the film. Leslie states that her husband is deployed with the Army National Guard (a Reserve Component of the US Army) and that if she does not return to work soon, her children will lose their health insurance. Part of her husband's mobilization training would have included a briefing for the unit's spouses on the benefits they (and their children) are entitled to while their family members are deployed, including enrollment in the (free) military family health insurance program Tricare. Even if Leslie chose not to attend the briefing, her husband would have been aware of the availability of Tricare to her and the children (and would have told her about it). Even if by some calamity he didn't tell her about Tricare, someone from the unit's family support organization (the Family Readiness Group) would have told Leslie about the availability of Tricare.
