MWSS-374 Expeditionary Air Field EAF PVC Patch — No Runway, No Problem
Before the first jet lands in the fight, the Marines of MWSS-374 already built the airfield it's landing on.
Marine Wing Support Squadron 374 was the unit responsible for operating and maintaining the Twentynine Palms Expeditionary Airfield (EAF) at the Marine Corps Air Ground Combat Center in Twentynine Palms, California — the largest Marine Corps base in the world. The EAF mission traces back to March 1977, when the 26th Commandant of the Marine Corps activated the expeditionary airfield concept, initially placing a small detachment from MABS-11 in charge. Through a series of redesignations — from MAG-16 Detachment Bravo to MWSS-173 to the Aviation Ground Support Element — the unit was finally redesignated as MWSS-374 on April 1, 1999, and grew to over 500 Marines strong. Part of Marine Wing Support Group 37 and the 3rd Marine Aircraft Wing, MWSS-374 provided every essential aviation ground support function: runway construction and repair, bulk fuel operations, aircraft firefighting and rescue, airfield lighting, expeditionary power generation, and perimeter security. If Marine aviation needed a place to land, refuel, and rearm in an austere environment, these were the Marines who made it happen. The squadron deployed multiple times in support of Operation Iraqi Freedom — in 2004, 2006, and 2008 — building and sustaining forward operating airfields in some of the harshest conditions on Earth, and deployed again for Operation Inherent Resolve from 2014 to 2015. Elements of the unit also supported Operations Desert Shield and Desert Storm in the early 1990s. MWSS-374 was officially deactivated on March 31, 2022, during a sunset ceremony at Twentynine Palms, but their legacy lives on in every Marine who ever built a runway out of nothing. This EAF PVC patch is a tribute to the Rhinos and every Marine who knows that airpower starts on the ground.
