I know with the Corps it definitely effects their promotions, at the very least. Guys will get passed over time and time again if they have domestic violence in their reacords. Depending on the situation, results can be a dishonorable discharge, which I think is appropriate. Unfortunately, the strict policies on it can be a double edged sword for the guys. Example & true story: an E-5, married, living on base, having a get together at his house. His wife and himself are both drinking. Wife gets mad and tries to stab him with a kitchen knife. When he tries to take the knife from her, he cuts her on accident. PMO arrives, he gets slapped with a DV and it goes in his jacket. I'm not sure how that turned out in the end but the incident is still on paper with the military.

Also. Many women are vindictive. They will get upset with their husbands and give a false report of DV or adultery ONLY TO get their husbands in trouble (adultery is also something the Corps has no tolerance for) so I'm not sure how accurate statistics are on military abuse.
