About 10% of sexual assaults in the military were males sexually assaulting males.
You can see the report here (2011):
This is interesting because the estimates for homosexual males in the military are about 1-2% of all military personnel. And yet homosexual male sexual assaults were 10% of all assaults.
That is much higher than their respective representation. And with the repeal of DADT, it will only climb. However there will be tremendous pressure, and much greater pressure than before, to cover up and lie about any homosexual perpetrator, in order to prove for political reasons that repealing DADT “worked.”
