One point on the new medal that sprung to mind - why, if in the DIN when it states the purpose the GSM is to fill a gap in metallic recognitin when an event doesn't warrant an OSM or campaign medal, does the medal state 'For Campaign Service' on the back?
What's the difference between an operation, a campaign and a sub-operation/campaign? If it's linked to scale, duration, intensity then why did 13 years in Afghanistan warrant an Operational Service Medal whilst Iraq was a campaign medal?
