Might I ask which camp that was?I think that would mainly have been Home Guard use.
In early 1980's in NI a UDR base in a sizeable old house that had been taken over at the start of the troubles was being vacated and sold off. The search team checked the place thoroughly and I signed off the FFE certificate. House duly sold off and renovations start.
A few weeks afterwards I am called to the Ops Room to explain myself as the ATO task is called in as builders have discovered a sizeable ammo cache! Fortunately it was as they broke down a wall and found a secret cupboard with a stash of WW2 date stamped ammo in a hideaway that had been plastered over. Probably in preparation for an invasion.
