Highway 1 through Baghdad, Taji, and on to Saddam Hussein's hometown of Tikrit, destroying resistance from Iraqi forces. The 1–67th Armor Regiment, in conjunction with other components of 2nd Brigade, 4th Infantry Division, secured and held multiple airfields and military complexes for later use by follow-on forces as far north as K2 Airfield near Bayji with all but one company of 1–67 Armor occupying FOB Scunion, which is located a short distance from Camp Freedom 1 (formerly known as Camp Warhorse). 1–67 Armor redeployed to Fort Hood with the rest of the 4th Infantry Division in April 2004. 1–67 Armor served a second tour of duty in Iraq from November 2005 to November 2006. The 1st Battalion – 67th Armor Regiment of 2nd Brigade, 4th Infantry Division, was operating out of Forward Operating Base Iskandariyah, located at the Musayyib power plant near the city of Musayyib, Iraq. The unit's mission, along with that of the 2nd Brigade, was to train Iraqi Security Forces to conduct operations independent of coalition assistance. 1–67 Armor Regiment was charged with patrolling, alongside Iraqi police and Army forces, the cities of Karbala, Musayyib and Jurf as Sakhr. During this tour, the battalion conducted a wide range of missions in support of OIF 05-07. These missions included stability operations, counterinsurgency, foreign defense, and high intensity combat operations.
