The mission of the 303rd Military Intelligence Battalion, "Longhorns," is to, on order, conduct multi-disciplined intelligence collection, exploitation, and limited analysis operations in support of the commander's information requirements during worldwide contingency missions within assigned areas of a Division, Corps, or Joint Task Force area of operations.

Commanded by Captain Emory L. Jones, the 3253rd trained until 8 June at Wincham Hall, Cheshire and then moved to quarters at Burton Bradstock, Dorset.

In 2004, the 303rd Military Intelligence Battalion deployed in support of Operation Iraqi Freedom, earning the Meritorious Unit Commendation for its Service during OIF.

The unit's numerous partnerships with military transition and provincial reconstruction teams greatly contributed to the increased readiness and capabilities of both the Iraqi army and police forces.

Soldiers with the 303rd MI Battalion Task Force Longhorns conducted more than 1,600 combat operations, generated 25,000 intelligence reports, captured 45 high-value targets and located 48 weapons caches and strongly supported the Afghan reintegration program, a top priority for the government of Afghanistan.
