Operation Iraqi Freedom
In Operation Iraqi Freedom, 6th ESB was responsible for fueling coalition forces as they moved northward through Iraq, and were entrenched in combat during the Battle of Nasiriyah. They also provided purified water supplies to the Marine Corps desert and urban encampments during Operation Iraqi Freedom. During Iraq's worst sandstorm in 20 years, Reserve Marines of the 6th ESB led by active duty Marines of 7th ESB Bulk Fuel Company detached to them constructed the longest fuel line in the history of the Marine Corps.
Continued support in 2004 to 2005 was given by Engineer Support Company from Portland, Oregon (reinforced by Detachment 1 Bulk Fuel Company A from Fort Lewis, Washington), and Bridge Company A from Battle Creek, Michigan. During this time Engineer Support Company was re-designated as Combat Service Support Company 113 (CSSC-113). Missions during this time included base operations in over a dozen different locations and resupply convoys during Operation Phantom Fury in November 2004. Four Marines were killed in action during this tour. Bridge Company A was attached to the US Army's 155th Engineer Group and rebuilt and maintained bridges all over South/Central Iraq. Their most significant repair mission was to repair a highway bridge at Checkpoint 34A (South of Camp Striker) on Main Supply Route Tampa during early November 2004 that had been damaged by VBIED attacks in order stop the flow of supplies and reinforcements to Fallujah during the campaign there. Projected to take 7 days to repair, Bridge Company A repaired the bridge while under fire in less than 32 hours.  
Operation Enduring Freedom

The majority of the company was based out of Camp Leatherneck, with small detachments of Bulk Fuels and Utilities Marines supporting more than a dozen sites throughout the Area of Operations. Combined teams from the engineer, motor transport, and heavy equipment platoons conducted extensive construction projects and road repairs for infantry and special operations units throughout the northern half of Helmand Province.
From 2012 to February 2013, 200 Marines from various units in the battalion, supported by individual augments from 6th Communications Battalion, deployed under the title of Engineer Company Bravo. The company integrated into Combat Logistics Battalion 2, serving in a similar role as the OEF 11-2 deployment.
