A colleague and myself visited the Merlin Force at RAF Benson last week and while I wouldn't normally plug a piece of ours so openly here, I believe this one might actually provide a response (through quotes from the Merlin Force itself) to some of what is being posted here.

As you will see, the Merlin Force WAS involved with exercises in Morocco, and while it doesn't feature in the script here, I can assure you that they were involved with the most recent MRX too...
