The Air Force are more married and less divorced than the general population is - for men. Air Force women are more divorced than the general population - 12.5% vs. 11.6% of American women in general.
Deployments are a big factor in military divorces, for men and women. This has long been known. The surprising finding a new study is that flight nurses - the most female part of the Air Force, and among the most likely to be deployed overseas - have the highest divorce rate, at 11.6%. Combat doctors, who are overwhelmingly men, are only 3.3% divorced. (Officers in general have a much lower divorce rate than the enlisted, at 4.4% overall).
I think I know what this means. Men are most jealous of the possibility that their wives would be sexually unfaithful. Military nurses in combat would be subject to more pressure, and temptation, to sexual infidelity than those same women would be at home, and more pressure and temptation than deployed men would be. Even if deployed female nurses are not, in fact, less faithful than they would be at home, it is reasonable to expect that some of their husbands would suspect that they were. Since another effect of deployment is to make communication much harder, dealing with those suspicions would be hard in that situation. Adding to the problem is the fact, also reported in this study, that non-military husbands at home are much less likely to use the Air Force's marriage support program than non-military wives are, the home husbands of deployed wives are more likely to do things that lead to divorce.
