Lt. Gen. Brett Sylvia, a high-ranking officer on the Pentagon's Joint Staff, was recently removed from his position as director for strategy, plans and policy, according to two sources familiar with the situation. The removal occurred earlier this week, and Sylvia has since retired.

Sylvia held the J-5 position, an office responsible for long-term strategic planning within the Joint Staff. His departure makes him the latest senior military official to be sidelined amid an investigation.
