There's some proper garbage being written here.
The scene of the attack is not on camp.
None of the OMQs or AMQs are behind the wire and I don't believe there were routine patrols in quarters on the day (my guess). I'm pretty sure there's no CCTV in the area near the Costcutter, unless it's on the shop front.
The part of the road that was closed was on Squires Hill, not within the village or the married patch, the local BBC TV report actually showed a camera shot looking away from Camp and there were no houses in view. A fact anyone of the jogging persuasion is grateful for as after a lap or two of the village Squires is a proper pain in the lungs..
How do I know the geography? I was stationed there for 9 years and 7 of those were in AMQs. I no longer serve but still live in the area and have occasion to visit from time to time.
