Most of the special operations personnel I had worked with were engaged in nighttime capture or kill operations, focused on specifical Qaeda—associated targets. As a group of highly trained operators, those men would step into their Humvees, helos, and Strykers at night alongside other highly trained men. Provided with the best possible intelligence and the best possible equipment, special operations forces snuck up on and attacked their targets. The night gave them the cover of darkness, and generators whirring in the cities often masked the sound of their approach.
