The brigade's Headquarters Company managed the engineer battalions but it also undertook its own missions, including humanitarian missions and public affairs assignments. It was supported by the brigade's Special Troops Battalion which provided a wide range of duties for the Headquarters. The task of detecting and removing IEDs proved particularly difficult for the brigade, as IEDs were a serious issue for coalition forces and the leading cause of casualties at the time. The 54th Engineer Battalion under the 130th was specially tasked with counter-IED operations on the over 300 kilometers of roads that the brigade was responsible for. The 249th Engineer Battalion was charged with maintaining the power grid throughout Iraq. They were required to assess 200 power stations throughout the country and make repairs to each one individually. The 84th Engineer Battalion was tasked with most construction projects in the Forward Operating Bases. These projects involved expansion of many of the larger FOBs as smaller ones were shut down and consolidated. One of the main focuses of the Battalion was the expansion of living quarters at Al Asad Air Base. The 565th Engineer Battalion was responsible for maintaining the supply yards housing building materials for the rest of the Brigade's battalions, and to ensure that the materials were dispersed and used as efficiently as possible. The brigade's mechanical and vehicle maintenance duties were provided by civilian contractors. These contractors also handled transportation of construction vehicles and vehicle parts to the theater.
