the Task Unit Raider and Task Unit Thunder (built around GROM) would become the task force's primary direct action assets, operating in conjunction on multiple occasions. Det One's first "real" mission - a close target reconnaissance operation - was aided by a GROM sniper, in which the target (a suspected insurgent sniper) was apprehended by the GROM sniper. Task Unit Raider first operated in and around Baghdad before being ordered by CJSOTF-AP to send its snipers to al-Najaf (a stronghold for the Mahdi Army) to relieve pressure on the 11th MEU. Det One proceeded to demoralize the militiaman by "wiping out" dozens of enemy combatants, confusing them as to the point of origin of the unrelenting lethal fire. In addition, Det One kept their marksman on their SR-25s around the clock-providing no respite for the militia. Det One's Scout snipers also carried out two successful countersniper operations, obliterating Shia insurgent positions and the snipers themselves with .50-caliber Barret M82 fire. In preparation for the Second Battle of Fallujah, Marines from the Det One, along with Green Berets from the 5th SFG, SEALs, and Marine Force Recon, were heavily involved in shaping operations prior to the 7 November D-DAY when coalition forces entered the city. However, the deployment also revealed interservice tensions. The Navy commander of Naval Special Warfare Squadron One did not utilize Det One as a cohesive unit but parceled its capabilities as needed. In particular, the intelligence section was parceled out to other Navy units, instead of supporting Det One operations, as the Navy lacked intelligence personnel who understood ground combat. Following the conclusion of the deployment in September 2004, the Marine Corps and USSOCOM continued to negotiate details of the long-term relationship through 2005, while Det One trained for a possible second deployment. Though deployment proposals were rejected on the basis that Det One was to provide the nucleus of the future permanent MARSOC organization, it was disbanded on 10 March 2006 and its members dispersed throughout the Marine Corps. The experience of Det One provided critical intelligence on the organization and integration of a Marine special-operations force into USSOCOM and was instrumental to the planning of MARSOC.
