Mr. Mansfield will serve as the principal advisor on all matters relating to the management, readiness, and strategic mobilization of the Navy and Marine Corps Reserve forces to both the Secretary of the Navy and the Assistant Secretary of the Navy for Manpower and Reserve Affairs.

“For too long, we have treated our Reserve forces as a separate, supplementary capability rather than an extension of our active-duty combat power,” said Secretary Cao. “Mr. Mansfield’s appointment is a clear message: we are modernizing our strategic reserve and fully capitalizing on the civilian expertise of our citizen-Sailors and Marines to win the future fight.”

Mr. Mansfield will oversee Navy and Marine Corps reserve force requirements. His immediate focus is modernizing Navy Reserve force generation, integrating civilian skills, and removing bureaucratic obstacles to rapid combat power delivery. He will also maintain vital coordination with the Navy and Marine Corps Reserve Policy Boards, congressional committees, and national veterans and reserve organizations to ensure cohesive policy execution in alignment with the National Defense Strategy.

“The challenges facing our Reserve components are not solved by doing things the way we always have,” said Mansfield. “To unlock the lethality of our Reserve forces, we must bridge the gap between active-duty requirements and the sophisticated capabilities our Reservists build in their civilian careers—particularly in cyber, logistics, and emerging technologies.”

Mr. Mansfield’s career uniquely prepares him to lead this transformation. Beginning his service as an enlisted Sailor, he deployed aboard USS Tripoli (LPH 10) and USS Tarawa (LHA 1) during Operation Desert Storm. Commissioned as an intelligence officer in 2000, he later deployed to Iraq alongside special operations units with Helicopter Combat Support Squadron 84 (HSC-84) "Redwolves" and the Joint Special Operations Air Command.

His command tours include leading high-performing units at the Navy Expeditionary Combat Command, the Naval Aviation Warfighting Development Center, and U.S. Pacific Command’s Joint Intelligence unit. In his civilian career, he retired as the Chief Operating Officer of a global energy trading firm.
