That guidance was signed on Feb. 7, 2025, and updated on April 1, 2025. On April 23, 2025, Secretary Hegseth further directed the USD(P&R) to provide additional guidance to the Military Department Review Boards, specifically, concerning the review of requests from service members and former service members who were adversely impacted by the COVID-19 mandate. That guidance was released on May 7, 2025.
