Maritime Expeditionary Security Force

Specialized units work together with MESF squadron staffs providing intelligence and communications.

Two Maritime Expeditionary Security Groups in San Diego, California and Virginia Beach, Virginia provide centralized planning, control, training, coordination, equipping, and integration of deployable units trained to operate in high density, multi-threat environments.

Units conduct force protection of strategic shipping and naval vessels operating in the inshore and coastal regions, anchorages and harbors, from bare beach to sophisticated port facilities.

Members of this community are highly encouraged to earn their Expeditionary Warfare Specialist Designation.
