[October 20, 2026] As noted in earlier articles (links here and here), I’m laying out the major elements, strategies, and inner-workings of the Iraq War as we approached the “Surge.” We were undergoing Base Development for a large increase in troop and equipment strength. The idea is that I will later turn this into a manuscript or book.
Multi-National Corps–Iraq (MNC-I) was the 3-star headquarters that ran day-to-day combat operations. It sat under Multi-National Force–Iraq (MNF-I), commanded in late 2006 by GEN George W. Casey Jr., and it was the counterpart to MNSTC-I which generated and trained Iraqi forces. MNC-I fought the war and employed both coalition and, once they were fielded, Iraqi units.
Headquarters was Al-Faw Palace at Camp Victory, on the Victory Base Complex west of Baghdad International Airport. In December 2006 it controlled more than 160,000 U.S. and coalition troops. On 14 December 2006, Casey passed the MNC-I flag from LTG Peter W. Chiarelli to LTG Raymond T. Odierno. That handover was a normal rotation, not a strategy change, though Odierno’s tour became the Surge element.
MNC-I was the tactical-level headquarters. Under it were the geographic Multi-National Divisions (and Force-West), plus supporting transition/advisory teams and enablers.
MND-Center (MND-C) was not yet a major element in the earliest part of 2007. It was created later in the spring/summer of 2007 (with the 3rd Infantry Division headquarters) as part of the Surge to take responsibility for the southern and eastern Baghdad belts.
The main internal staffs of MNC-I were these:
Command group. Commanding general, deputy commanding generals (operations and support), chief of staff, and command sergeant major. Brigadier generals sat over the main functional areas and ran the battle-update assessment.
Coordinating staff. These were the sections that advise, plan, and coordinate actions in their functional areas or warfighting functions, and they exercise planning and supervisory authority over designated special staff officers. Per FM 6-0 Mission Command: Command and Control of Army Forces(August 2003).
- C1, personnel. Strength, replacements, casualty reporting, and morale and welfare for the corps and its divisions.
- C2, intelligence. Enemy situation, collection, and the intelligence estimate. This was Annex B of the corps order.
- C3, operations. The largest section, split between current operations and plans. Current ops ran the daily fight, the BUA, and the commander’s critical information requirements. Plans wrote the campaign order. COL Murray was the C3 in January 2007. Annex C of OPORD 07-01 covered population control, Iraqi security-force development, reception and onward movement, ISR, engagement and reconciliation, and information operations. A C3 Air cell handled aviation, airspace, unmanned aircraft, and MEDEVAC.
- C4, logistics. Supply, maintenance, movement, and life support for a force that was about to grow by five brigade combat teams with as little extra support structure as Odierno could accept. Annex D.
- C5, plans and policy. Future operations and the campaign design, often nested with C3 Plans. This is where the surge concept of operations was built before the extra brigades closed.
- C6, signal. Communications and the network, published as Annex K.
- C8, resource management. Funding and contracting interface.
- C9, civil-military operations. Governance, economics, essential services, internally displaced persons, and the link to provincial reconstruction teams and the Embassy. That work appeared as Annex G (economics, effects, force generation, assessments).
Special staff. They provide specialized professional or technical expertise in specific areas and are organizaed by those technical/professional responsibilities rather than by broad warighting functions.
- C7, Engineer. Construction, basing, route clearance, and reconstruction. In January 2007 the engineer chief was COL Juan Fernandez. The immediate problem on his desk was housing the incoming Surge brigades with the existing engineer force.
- Fires. Corps artillery and targeting.
- Provost marshal. Law enforcement and detention operations.
- Staff judge advocate.
- Surgeon, chaplain, public affairs, inspector general, and political advisor.
- Special technical operations.
- Meteorological and oceanographic.
The practical split inside the palace was simple. C3 and C2 ran the current fight. C5 and the effects and C9 cells built the campaign. C4 logistics and the C-7 Engineers had to beddown the incoming Surge without a matching surge in support troops. The Iraqi Assistance Group and the partnered transition teams were the Corps’ link to the forces MNSTC-I was generating.

I think i can see where you’re headed with this article. And a new series that will tell us more about how the work worked from the view of an engineer officer.
