My two penneth worth.
One of the worst phrases in the military is "because we've always done it that way".
The RPAS crews are tangibly involved in the current campaign. They don't meet the criteria for risk and rigour but perhaps this should be revisited.
I would go for a campaign medal that recognises those who have served on the ground or in the skies over Iraq and Syria. Fleshy bodies who have actually flown or served in Syria and Iraq would get the medal and rosette.
Apologies to the Engineers without which none of us would ever get to where we need to be. One team one fight and all that.
