I did read somewhere that one of the Para units had a habit of "recovering" items after bomb blasts in N.I. back in the 70's.
After one tour everyone had a nice shiny wristwatch and could afford an overseas holiday.
It ended after a DMS footprint was left in one establishment and the RMP got lucky by hitting the only loose ceiling tile and finding a kitbag full of swag.
Er, allegedly.. that pretty much happened after every bombing of a jewelers mucka. .. problem, so i'm ..er ..told was that the watches often damaged by the blast and shock wave, never lasted long and nor did loads and loads of gold chains get wrapped around cardboard and posted home, oh, no they never did .
Nor where the RUC often first on the scene and we, ...er ..some would arrive just in time for them to say.. 'Ok, you're here , so we're off ' while smiling like people who had just happened upon something shiny.
