English: U.S. Army Sgt. Mario Nelson, a 26-year-old infantryman from Brooklyn, takes a break during a foot patrol with Iraqi soldiers June 11, 2006, in Hit, Iraq � a city of 30,000 in Al Anbar Province. Nelson was killed Oct. 1 in combat operations in Hit. Spc. Luis Enrique Tejeda, a 20-year-old soldier from Lynwood, Calif., was also killed during combat operations the day prior to Nelson. Both were memorialized recently by fellow soldiers and Marines � Tejeda Oct. 6, Nelson Oct. 4. The battalion is attached to Regimental Combat Team 7, the Marine Corps command responsible for providing security to more than 30,000 square miles of Iraq�s western Al Anbar Province. Both soldiers were members of the battalion�s Alpha Company. Tejeda and Nelson were the battalion�s fourth and fifth soldiers killed in action since the unit arrived in Iraq in February. The battalion has spent the past eight months providing security in Hit, a city of 50,000 in the western Al Anbar Province, where arguably some of the fiercest fighting in Iraq takes place. The soldiers face small-arms fire and improvised explosive attacks daily. The battalion, also known as �Task Force 1-36,� was recently extended for six more weeks of duty in Iraq.
