Marine Detachment (CV 41)
U.S. Marine Corps
The Marine Detachment (MARDET) aboard USS Midway (CV-41) was established to provide security, ceremonial duties, and support for shipboard operations. Activated with the commissioning of the carrier in 1945, the MARDET played a key role during major conflicts, including the Korean and Vietnam Wars, manning gun stations and overseeing the security of nuclear weapons. Marines from the detachment also participated in humanitarian missions and liberty port security throughout the ship’s decades-long service. The MARDET was eventually deactivated in the late 1990s as the Navy phased out Marine detachments from aircraft carriers.

Marine Support Battalion
U.S. Marine Corps
The Marine Support Battalion (MSB) was established in 1955 to provide specialized signals intelligence (SIGINT) and communications support to the United States Marine Corps and joint military operations. Originally activated at Camp Lejeune, North Carolina, the battalion deployed detachments worldwide, offering critical intelligence collection and analysis during the Cold War, Vietnam War, and subsequent conflicts. In the 1990s, the battalion was reorganized, with its operational elements absorbed into the Marine Cryptologic Support Battalion (MCSB) under the National Security Agency. Throughout its history, the unit earned recognition for its vital role in enhancing situational awareness and supporting combat operations with timely, actionable intelligence.

Moffett Field California
U.S. Marine Corps
Moffett Field, located in California's San Francisco Bay Area, has a rich military history dating back to its commissioning in 1933 as Naval Air Station (NAS) Sunnyvale, later renamed in honor of Rear Admiral William A. Moffett. Originally established for the operation of rigid airships like the USS Macon, the base played a key role in early naval aviation and anti-submarine warfare during World War II. Throughout the Cold War, Moffett Field hosted patrol squadrons equipped with P-3 Orion aircraft, supporting maritime surveillance and reconnaissance missions. The base was officially closed as a military installation in 1994, transitioning to NASA Ames Research Center, but it still serves as a site for military reserve units and aerospace research.

MSSG 15
U.S. Marine Corps
The Marine Expeditionary Unit Service Support Group 15 (MSSG-15) was a logistics unit within the United States Marine Corps, primarily tasked with providing combat service support to the 15th Marine Expeditionary Unit (MEU). Established to enhance the operational reach and sustainability of the 15th MEU, MSSG-15 participated in numerous deployments, including humanitarian missions and combat operations such as Operation Enduring Freedom and Operation Iraqi Freedom in the early 2000s. The unit excelled in delivering supply, maintenance, transportation, health services, and other critical support functions during amphibious and expeditionary missions. In 2006, MSSG-15 was redesignated as Combat Logistics Battalion 15 (CLB-15), reflecting broader changes in Marine Corps logistics structure.
