I want to know the answer to the following question:
Why did the USAF change its training methods on UAVs in 2014?
All the background I'm provided with is that "In spite of an urgent need for UAVs or drones to provide round the clock coverage for American troops during the Iraq War, the USAF did not establish a new career field for piloting them until the last year of that war and in 2014 changed its RPA training syllabus again, in the face of large aircraft losses in training, and in response to a GAO report critical of handling of drone programs.". Is that enough to answer the question?
Answer: yes
