The 303rd Military Intelligence Battalion deployed in support of Operation Iraqi Freedom on three occasions between 2004 to 2009. As the Operations Battalion of the 504th MI Brigade, the Longhorns formed the Analysis and Control Element (ACE) for the III Corps Phantom Warriors.
The Battalion first deployed to Iraq in 2004 to support the CJTF-7 Headquarters, formed by III Corps. In 2006-2007, the Longhorns once again took their post within Camp Victory's Al Faw Palace as the Combined Analytical Control Element (CACE) and provided support to the Multi-National Force Iraq (MNF-I) and Multi-National Corps Iraq (MNC-I). The intelligence support that the Battalion provided was essential to the success of the "Surge" that changed the tide of the war.
The Battalion would deploy to Iraq one last time in late 2008 where they once again served as the Corps' CACE. Additionally, Charlie Company's HUMINT collection Teams (HCTs) provided direct support to four brigade combat teams and the 303rd's numerous partnerships with military transition and provincial reconstruction teams greatly contributed to the increased readiness and capabilities of both the Iraqi Army and its police forces
During the 303rd MI Battalion's time in Iraq, the Longhorns received 2 additional Meritorious Unit Commendations, citing the Battalion's providing of "valuable" and "actionable" operational intelligence that greatly enhanced mission success.
