The big scotsman in question from my few dealings was nothing more than a large obnoxious glaswegian bully. He took great pleasure in picking favourites and then physically abusing those not in said category.
Possibly his finest moment came in the "Street", for those who remember the old Sgt's mess at Aldergrove, when a certain mild mannered crewman asked him to leave as he was being his usual punchy self. On trying to stand his ground in his sad time honered fashion he failed to realise that "our jack" was a tae kwondoo master who proceedeed to batter f@@k out of him much to the joy of all around.
Various stories have done the rounds since he left the service none more satisfying than the the rumour that he ended up in Barlinnie. Not sure how true the story is but seems quite a fitting end for said individual.
