Senior Airman Santos Rodriguez, 28th Mission Support Group client system administrator, repairs and troubleshoots a computer here, April 16. Airman Rodriguez troubleshoots 35 to 40 computers per week, saving the Air Force thousands of dollars. If Ellsworth purchased new machines instead of having specialists repair them, it would cost about $18,000 in new computers. (U.S. Air Force photo/Airman 1st Class Joshua J. Seybert)
