The Navy has a serious problem with rapes, sexual assaults and violations of "fraternization" rules at its Orlando, Fla., training center, and often has failed to seek appropriate punishment for offenders, the Washington Post reported Monday.

In the 18 months that ended June 30, the Navy's inspector general reported there were at least six rapes of female students or recruits at the Orlando Naval Training Center, but the Navy had not prosecuted any individuals, according to the results of a Pentagon investigation quoted by the Post.
