Yes, like many others, General Vance had to be protected because he was seen as a rising star during his career and therefore a good move for the military. It wasn't in the interest of the Forces to cast him aside or investigate him due to an allegation of sexual misconduct or assault. You don't want to tarnish the career or cause the loss of a valuable co-worker who is your right-hand man, for example. So General Vance's superiors or peers certainly had an interest in hiding these things, because they liked his work, operationally speaking.
