during this deployment. On 1 August 2004, the 4th Infantry Division (Mech) was ordered to restructure and reorganize under the U.S. Army's concept of modularity. This would set the division to become the Army's first fully digitized modular division. The 2nd Brigade Combat Team would lead the conversion and become the Army's first modular Brigade Combat Team – "Unit of Action". Under the restructure the Thunder Battalion reorganized and became the first modular "fires battalion". This meant the battalion would no longer be assigned to the Division Artillery but would fall under the total control of the 2 Brigade. On 1 January 2005 the Thunder Battalion completed its conversion with the activation of its support company, G Company, 204th Support Battalion. The unit's mission was to maintain warfighting readiness and on order, deploy by land, sea, or air to conduct combat operations by coordinating fire support that provides safe, timely, and lethal fires in support of the 2nd Brigade Combat Team, 4th Infantry Division. As of January, 2006, OIF 05-07, the 3rd Battalion – 16th Field Artillery Regiment was deployed to Forward Operating Base Duke, located in Najaf, Iraq, as well as Forward Operating Base Kalsu and FOB Falcon in Southern Baghdad in support of Operation Iraqi Freedom. Most of the unit, along with the rest of the 2nd Brigade, 4th Infantry Division was tasked with training Iraqi Security Forces so that they can conduct operations independently of coalition troops, with the exception of 2 squads from B Battery, guns (M109A6 PALDIN) B15 and B18 who conducted live counter-fire operations in support of 1-67 Armour and 2-8 Infantry (Mechanized), both of 2nd BCT, 4ID.
