I'll have you know I was rocketed 12 times in KAF. I was personally targeted - out of 12,000 inhabitants - by a war lord and had to seek sanctuary in Timmy Horton's. I tracked him down years later, where he was working as a dog-fondler for a charity in Kabul. He has now been successfully rehomed in Rotherham.I think most people (particularly single blokes looking to impress) make their time sound more interesting, whether it was landing at Normandy a week after D Day or coming under attack from the Taliban because they fired a rocket into KAF, some people then cant retract their stories when the adoring public ask more questions and build up a picture of a hero fighting bravely for Queen and country.
Of course some bellthronks go full on Bugsy and come out with the most unbelievable fibs about the SAS. but generally they would be the type to own several Lamborghinis which are all in the garage, have a highly paid CEO job while scrounging the cost of a pint and have a penthouse somewhere on the council estate where they reside.
