Major operations that the battalion participated in during its deployment included Operations Matador, New Market, Spear, Sword, River Bridge, Outer Banks, and Quick Strike. The battalion rotated out of Iraq in late September 2005, and deactivated on January 3, 2006. Forty-six Marines and two Navy Corpsmen serving with the battalion in Iraq were killed in action. The company received the most combat losses of any infantry unit since the Vietnam war. A memorial paying tribute to them was erected at the Battalion headquarters in Brook Park, Ohio and was dedicated on November 12, 2005.
