The Pentagon said Thursday it has made a criminal referral in an alleged leak case, saying the removal of Army Lt. Gen. Brett Sylvia as the Joint Staff's director for strategy, plans and policy was necessary "to protect sensitive information," The Washington Post reported.
The unusual announcement followed reports that Sylvia had been abruptly removed from the post, known as J-5 and regarded as the Pentagon's top military planning job. In that role he reported to Gen. Dan Caine, the chairman of the Joint Chiefs of Staff.

The Pentagon's case has stunned some of Sylvia's colleagues, some of whom have questioned the narrative promoted by Defense Secretary Pete Hegseth's team, according to the Post.
When Sylvia was removed earlier this week, the Pentagon did not publicly explain the decision. A Joint Staff spokesperson thanked him for his 32 years of distinguished service. Sylvia has since retired.
He is the second officer in the J-5 post to be pushed out under Hegseth. His predecessor, Lt. Gen. Joseph McGee, was forced to retire last October, and nearly two dozen generals, admirals and other senior leaders have been fired or forced out under the defense secretary.
The shake-up comes as President Donald Trump weighs resuming major military operations against Iran.
