U.S. Marine 1st Lt. David Rooks, an operations advisor

U.S. Marine 1st Lt. David Rooks, an operations advisor with the 3rd Battalion, 3rd Marine Regiment Embedded Training Team, and 32-year-old native of Garland, Texas, uses binoculars to determine target placement for a machine gun range with Afghan National Army soldiers assigned to 2nd Kandak, 1st Brigade, 215th Corps, here, Feb. 21. As Afghan forces become more independent in the conduct of security operations in Garmsir district, the ETT Marines are focused on teaching ANA leaders how to employ their men in this mission. Rather than focusing solely on weapons handling and employment during the 20-day course, Marine instructors concentrated on developing ANA noncommissioned officers as machine gun team leaders.
