In late 1993, segments of the battalion deployed to Colombia, South America to participate in the construction of several community and infrastructure projects. Those segments returned to Fort Rucker in early 1994. In mid-1994, the battalion is relocated to Fort Polk, Louisiana due to the Base Realignment and Closure (BRAC) and to support the Joint Readiness Training Center (JRTC). This relocation did not include Bravo Company.

B Company and HHC were primarily operated from Camp Ramadi. Elements of the battalion participated in the Battle of Ramadi (2006) establishing combat outposts (COPs) and patrol bases throughout the city. These operations were often executed under direct fire and/or indirect fire. Four members of the battalion were KIA during the duration of the deployment—two due to mortar attacks and two to improvised explosive devices.
