Jayland, is correct and that was the basis for Clegg' s conviction.
Regarding BATCO' s comment, IMHO the RAF policy was immoral. Give a man a gun, he becomes a target. No ammunition and he is a lamb to slaughter or She even.
In 1972, at Akrotiri, we had a high security alert and a exercise was called. Air Cdre Stacey made the decision that everyone would be live armed. Our 9mm mags had the bullets secured with cellophane, more a precaution against loose rounds.
