In 1994, he resigned his commission in the Reserves and enlisted in the Active Army to become a Special Forces medical sergeant.[1] In 2005, he deployed to Afghanistan for Operation Enduring Freedom as a medical sergeant and a team's operations sergeant.[4]
On June 23, 2006, O'Connor and his team were ambushed by over 250 Taliban fighters in southern Afghanistan. During the ensuing 17½ hours of intense combat, two soldiers were seriously wounded. The Afghan translator with the team radioed for permission to kill the two wounded soldiers and himself to prevent the Taliban from capturing, then torturing, mutilating, and executing them.[5]
O'Connor started to crawl out to assist the two wounded soldiers but could not get low enough to avoid detection. He then removed his body armor and slowly crawled toward the two soldiers, taking a full 90 minutes to crawl 200 yards, while machine gun bullets passed close enough to cut down the grass around him. Eventually reaching the wounded, O'Connor gave them first aid, then moved them to a more secure position.[6] Afterwards the team sergeant was killed, at which point O'Connor took command of the team.[7]
Covered by a United States Air Force plane, the team was able to withdraw. They suffered two dead and one seriously wounded but had killed over 120 Taliban fighters.[8]

Citation:
The President of the United States of America, authorized by Act of Congress, July 9, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Distinguished Service Cross to Master Sergeant Brendan W. O'Connor, United States Army, for extraordinary heroism in combat as the Senior Medical Sergeant for Special Forces Operational Detachment Alpha 765 (ODA-765), Company A, 2d Battalion, 7th Special Forces Group (Airborne), in support of Operation ENDURING FREEDOM, in Panjawal District, Kandahar Province, Afghanistan. On 24 June 2006, while conducting Operation KAIKI, Sergeant O'Connor led a quick-reaction force to reinforce a surrounded patrol and rescue two wounded comrades. He maneuvered his force through Taliban positions and crawled alone and unprotected, under enemy machinegun fire to reach the wounded soldiers. He provided medical care while exposed to heavy volumes of Taliban fire, then carried one of the wounded 150 meters across open ground to an area of temporary cover. Sergeant First Class O'Connor then climbed over a wall three times, in plain view of the enemy, to assist the wounded soldiers in seeking cover while bullets pounded the structure around them. Sergeant First Class O'Connor assumed duties as the detachment operations sergeant and led the consolidation of three friendly elements, each surrounded, isolated, and receiving fire from all directions. Sergeant First Class O'Connor's distinctive accomplishments and dedication to his comrades are in keeping with the finest traditions of military service and reflect great credit upon himself, the Special Operations Command Central, and the United States Army.[9]
