While the report will show that the number of reported assaults in fiscal year 2012 rose only 6 percent to 3,374 — up from 3,192 a year before — the number of people who made an anonymous claim that they were sexually assaulted but never reported the attack skyrocketed from 19,000 in FY11 to 26,000 in FY12.

Members of Congress will be briefed on the report early tomorrow afternoon, and then Major General Gary Patton, the Director of the DoD Sexual Assault Prevention and Response Office (SAPRO), will brief the media.
