I am not and have never been aircrew, but do have a view on this.
I feel that UAS/RVP crews should get campaign medals as they are involved in the campaign and are killing people.
I imaging they see exactly what they are doing, and taking of life while at in a comfy chair (I see no connection at all to computer games here at all) could well take a huge mental toll at some point.
In my previous role I can only say that the 'it's him or me' scenarios have left no lasting effect on me, whereas the 'its going to be him, because that's my job' situations have had a much greater effect on me.
