The battalion was responsible for security for three bases south of Baghdad and corresponding route security along main supply routes between Baghdad and Kuwait. The battalion was reorganized and retrained for this deployment which included all but one of the companies (Bravo) deploying as provisional infantry units. The battalion returned to California in March 2005 where it was restructured into a Combined Arms Battalion shortly thereafter. First battalion's Bravo Company, was equipped with M1 Abrams. The first battalion's Bravo Company (along with other attached battalion elements to specified active duty units) received a Valorous Unit Award for actions as part of the 1st Brigade, 25th Infantry Division in early 2005 as part of operations in support of Iraq's first elections after the fall of Saddam Hussein. 2005–06 Iraq

In Iraq, Bravo Company was responsible for the security of more than 2,200 detainees at Baghdad Central Prison (formerly known as Abu Ghraib) until June 2006 when the camp was closed. During their time at the prison, Bravo Company Soldiers foiled several escape attempts. Upon the closure of the prison, it was then the responsibility of the unit to transport approximately 5,000 detainees to various holding facilities throughout Iraq. Following that mission, Bravo Company Soldiers were responsible for convoy security and operational control of a forward operating base where the company's convoy team operated without any coalition or civilian casualties for more than 10,000 miles. In December 2006, Bravo Company demobilized at Fort Lewis, Washington before returning to San Diego, California. The second battalion's Bravo Company received one Iraq Campaign streamer with the following inscription: NATIONAL RESOLUTION. Bravo Company also received a Meritorious Unit Commendation as part of the 43rd Military Police Brigade, Rhode Island Army National Guard.

In turn, the first battalion was augmented with Alpha and Bravo companies from the first battalion, 184th Infantry Regiment. After mobilization, the first battalion completed training in Fort McCoy, Wisconsin, and arrived in Iraq in October 2008. While in Iraq, the first battalion's Echo Company and Alpha and Bravo companies from the first battalion, 184th Infantry Regiment were attached to the 30th Support Battalion. The remainder of the first battalion performed a security force mission throughout Multi-National Division-North at COB Speicher near Tikrit, Iraq.

The first battalion's Echo Company received two Iraq Campaign streamers with the following inscriptions: IRAQI SURGE and IRAQI SOVEREIGNTY and a Meritorious Unit Commendation. 2008–09 Kosovo

In October 2008, the first battalion's Alpha Company was mobilized under the command of the 184th Infantry Regiment for a deployment to Kosovo as part of the 40th Infantry Division as the only mechanized infantry company. The company mobilized ahead of other units and conducted most of its training separate from its parent unit, because of the need for specialized gunnery training on the company's Bradley vehicles. This training was conducted at Fort Irwin in November and Camp Shelby in December. Once the gunnery training was completed, the company traveled to Camp Atterbury to join its parent unit to complete the required training. The company traveled to JMRC Hohenfels for additional training, before arriving in Kosovo in February. The company was utilized as one of three maneuver companies tasked with providing a safe and secure environment and ensuring freedom of movement in accordance with United Nations Resolution 1244. While accomplishing this mission, the company also was required to both maintain their Bradley Fighting Vehicles as well as their proficiency with using them. In November 2009, the company departed Kosovo to conduct demobilization operations at Fort Lewis near Seattle, Washington and returned to California a few weeks later. While the battalion did not receive campaign participation credit, those Soldiers who served with Alpha company during this deployment received the Kosovo Campaign Medal and the NATO Non-Article 5 Medal. Redesignation
On 2 February 2016, the 1st Battalion of the 185th Armor Regiment was redesignated as 1st Battalion of the 185th Infantry Regiment, due to the transition of the 81st Armored Brigade Combat Team to a Stryker brigade. This unit inherits the lineage of the 185th Armor and is not connected with the previous 185th Infantry. Subordinate units
