The outrage over sexual assault in the military has focused largely on female service members, and with reason: A woman in uniform is much likelier to be targeted than a man, Pentagon surveys indicate. But because male service members greatly outnumber females, officials believe the majority of sexual assault victims — 53 percent in 2012 — are men. These men — an estimated 13,900 last year alone — are far less likely than women to report an attack. Only 13 percent of reports last year were filed by men, military data show. But the disparities do not end there. The Sun found that when men do report a sexual assault, military authorities are less likely to identify a suspect, to refer charges to court-martial or to discharge the perpetrator than in cases in which the victim is a woman. Through vignettes of men who were sexually assaulted, graphics, photography and video, The Sun explains how so many cases go unresolved.
