CINCLANTFLT MARINE DET.

The **CINCLANTFLT Marine Detachment** (Commander in Chief, Atlantic Fleet Marine Detachment) served as a specialized unit of United States Marine Corps personnel assigned to the staff of the Commander in Chief, U.S. Atlantic Fleet (CINCLANTFLT). Established to provide security, ceremonial, and administrative support, the detachment was based at CINCLANTFLT headquarters in Norfolk, Virginia. Marines of this detachment played vital roles in both the day-to-day operations and special events, representing Marine Corps professionalism to senior Navy leadership and visiting dignitaries. Throughout its existence, the CINCLANTFLT Marine Detachment embodied the close cooperation between the Navy and Marine Corps, supporting Atlantic Fleet missions until organizational changes in the late 20th century led to its deactivation.
