2nd Heavy Brigade Combat Team deployed to Baghdad, Iraq in November 2010 in an advise and assist role as part of Operation New Dawn under the command of COL Paul T. Calvert. The brigade HQ was located at Victory Base Complex, where it was co-located within the USD-C Division HQ building and shared the same TOC. This unique C2 relationship earned the brigade the moniker of the "Luckiest Brigade in the Army" from the USD-C commander. The brigade was placed under USD-C (initially 1st AD, then 25th Infantry Division after Dec 2011) and was single-handedly responsible for the entire province of Baghdad. As the brigade responsible for the "center of gravity" (i.e. Baghdad) for United States Forces-Iraq, the 2nd "Dagger" Brigade was responsible for advising and assisting 50% of the Iraqi security forces within Iraq to include two Iraqi corps HQ (the Karkh Area Command and Rusafa Area Command) and seven Iraqi divisions (6th IA, 9th IA—Mechanized, 17th IA, 11th IA, 1st FP, 2nd FP, and 4th FP) and 50,000 Iraqi policemen.
