You're failing to account for the fact there are 4 times the number of men in the environment than women. If the number of male vs. female rapists are proportionate to the number of men and women in a population--and it usually is--that rate should be 4x not 3x. If the number of male vs. female rapists are proportionate to the number of men and women in a population--and it usually is--that rate should be 4x not 3x.

Actually this is far from certain. Part of the problem with sexual abuse in the military is that there's a clear power discrepancy between different levels of command, and the huge disproportion of men to women in the chain of command makes even small differences very extreme. If there is a single female officer in every 200 soldiers abusing her power and sexually coercing multiple men, that will drastically skew the numbers far more than a single male officer per 800 men abusing his power to sexually coerce multiple women.

By proportion women are more likely to be rapists in the military than men.

Assuming no repeat offenders, yes, the difference is exactly 1%. Not statistically significant, but it's there.

Wouldn't it make more sense and be more productive to address rape as a non-gendered issue of mental health intervention rather than shoe horning it into "woman-as-victim" narrative?

It would make more sense if context was removed, but we can't remove the context. We can't just ignore WHY this has been a problem for so long: the people who are targeted (to avoid the use of the word "victim") feel unable to report their experience or get help because the chain of command and military justice system are dominated by people who think "men can't be raped" and "women who claim rape did something to instigate it." Such people, traditionally and in this case, happen to be men.

You keep saying that women shouldn't think of themselves as powerless, but acknowledging that they do not have power within a system does not make them powerless. Acknowledging that they felt powerless doesn't give them a "victim mentality." They are expressing how they honestly felt in the circumstances they were in. And they are moving on from that and pushing for change.
