Unfortunately they do not, even if he has tons of evidence on his side.  It also doesn't help that the UCMJ (military rules that apply to all servicemembers) prohibits adultery, which means if you are caught having relations with someone else while you are legally separated or in divorce proceedings, your career could be in jeopardy as it's a chargeable offense. I know one guy that wanted to leave his wife so he kicked her out.  She called his 1st Sergeant (enlisted liason to the unit's commander) and then he got a phone call from him saying he can't do that, he has to be the one to leave and stay somewhere else (like the barracks on base).  I knew another guy that found out his wife got together with another co-worker during her deployment.  She had put up pictures of them together travelling all over Europe (we were stationed in the UK) on her Facebook and seeing him in his truck (easily identifiable) all over base, but was told he couldn't do anything.  I knew other who divorced his wife because she was cheating and doing drugs, and the judge in the state they got married decided to ignore that and give the mother FULL custody of their child because the military is an unstable lifestyle. Additionally, if they were married long enough the wife (10 years while in the military) is entitled to a portion of his retirement regardless  of the divorced status.
