In the same way that during the outdoor survival/ escape and evasion phase in the Black Mountains the South Cerney staff (1962) put it about that the SAS would come down from Hereford and participate - so woe betide you if you were caught. What actually happened was that one flight was detailed off to double back from a night navigation exercise and raid the camp shouting 'SAS' and other unlikely battle cries.
