1976 Norfolk Tanker Base, middle of a 10 day TACEVAL and everyone getting a bid hacked off, but at least we could go and have a few drinks at lunchtime before we started a night shift couldn't we? Anyway a couple of us were tasked to guard the back gate by the golf course so off we trot with our pick axe handles, not allowed SLRs during an exercise, and man the gate. Later that night nature works its course and my fellow guard needs to relieve himself rather desperately but the only problem was we still had another 30 minutes on guard. Easy solution I keep eye on gate while he trots off into the trees by golf course and starts to relieve himself. At which point there is an almighty scream and a camouflaged figure jumps up from the undergrowth. Turns out the intruder had been there for a few hours waiting for his moment to head out across the airfield and didn't expect "rain" that night. Needless to say we were heroes that night, but decided to ease off on the lunchtime sessions.
