The particular nature of drone warfare is also a contributor to the higher stress levels. While the number is very small, officials who conducted the study said they did encounter a handful of pilots who suffered symptoms of PTSD — post-traumatic stress disorder — directly linked to their experience running combat operations.

They watch someone’s pattern of life, see people with their families, and then they can be ordered to shoot. –NPR.org » Report: High Levels Of ‘Burnout’ In U.S. Drone Pilots.
