Halfway through our major incident exercise in Cyprus, I'm in the med center on Comms.
Call comes on through the emergency line from one of the RMP to the effect of there being a fractured fuel line, fire, disaster, civi houses at risk... Fortunately the SMO was in the room and the call was on speaker. Three times I asked him to confirm if this was exercise or noduff. Noduff called each time, immediate endex called and noduff major incident declared.
All military med centres and akrotiri hospital placed on standby, RAF rescue helicopter, one tonne ambulances called in from the infantry, etc
Surprise surprise, it was an exercise call.
I was several offices away from the SMO (and at least 2 sets of closed doors) and I could hear quite clearly how upset he was while he debriefed the RMP OC.
On the plus side the response was by the book and went smoother than a well oiled smooth thing
I've only got one dit of that sort but it's not identical. I was over in BATUS, manning the Ops Room as staff, enduring another day of trying to keep the Battlegroup and OPFOR guys and gals killing themselves on the range roads by speeding like the complete braindead idiots they were, when a call came in over the net reference the MO's Rover that was tasked to go on an exercise casualty having managed to roll itself over.
(If anyone's been to BATUS they know how slippery the roads were on the training area, so rollovers and excursions into ditches were pretty common.)
It was quite exciting for a few minutes trying to sort the CASEVAC out after confirming that it was a genuine emergency. Especially since one of the main callsigns tasked with sorting stuff out happened to be the one that was involved in the proceedings...
