The more those who excitably object to the use of the word drone do so, the more some of us are likely to continue to use the term.
Besides, it's quite clear that the precise role of a drone is contextual, and not limited by a (useful) descriptor that everyone, whether serving or civvy, can grasp. Making up pompous military terminology (UAS,RPAS) reflects badly on those who do so. I guess it got some t**t promoted though.
