Tech. Sgt. Andrea Patterson performs her daily maintenance routine on a tactical meteorological operating system June 23 at Forward Operating Base Kalsu, Iraq. Sergeant Patterson and two other Air Force weather forecasters provide 24-hour-a-day weather updates to the Army 3rd Infantry Division's operations occurring in the Triangle of Death area. The instantaneous weather information the battlefield weathermen are able to provide are critical to the success, and to the safety of the 3rd ID's ground and aviation operations. Though Sergeant Patterson is attached to the 3rd ID, she officially falls under the recently formed 3rd Expeditionary Weather Squadron headquartered on Camp Victory in Iraq. She is deployed from Detachment 6 of the 7th Weather Squadron from Wiesbaden, Germany. (U.S. Air Force photo/Master Sgt. Jim Varhegyi)
