280SU 1974'ish - TACEVAL. I'm on the Ops roof at night looking for the nasty invaders - the SAS in this case.. I spot 2 guys at the perimeter fence, one on the others shoulders, who then leaps into the compound and does a runner. I pick up the field telephone at my end of the roof, only to find it's dead. I then run over to the other side of the roof and pick up the second field telephone handset whilst sitting myself on a bunch of 'sandbags'. The 'sandbags' say to me..."...and that bugger won't work either"... oh the moments when you discover the true colour of adrenaline!
