This was done because many of the military occupational specialties of the Marines in a MWSS are identical to that of the Logistics Combat Element (LCE) required by a MSSG.

From February to September 2006 and for the first time in over 10 years MWSS-274 deployed to Al Asad Airbase in Iraq as a complete squadron under her own guidon to conduct Aviation Ground Combat Support.

In December 2007 the squadron was again re-designated from a wing service support squadron to a security battalion and after pre-deployment work ups, the unit in February 2008 again deployed to Al Asad Air Base in Iraq this time as a security force in support of Operation Iraqi Freedom.

Under command of Lt Col. Anthony Ference and Sgt Major William Grigsby, the unit deployed under its own guidon, conducting Aviation Ground Combat Support, only for the second time in two decades.

In February 2010, MWSS-274 deployed to Camp Leatherneck in Helmand Province, Afghanistan in support of Operation Enduring Freedom (OEF).

MWSS-274(-) worked diligently with Redeployment and Retrograde in support of Reset and Reconstitution Operations Group to return salvageable USMC equipment to the U.S. while also disposing of materiel excess.

In November 2014, MWSS-274 won the MajGen WPT Hill Award for best expeditionary field mess in the Marine Corps.
