the army here sends it bad boys to Colchester(Colly) and it's certainly true that most SNCO's have spent some time there, the army believes they are better soldiers for going there. In the RAF and Navy though you'd probably spend your time there but be dismissed though they won't admit that. It could be something the young man would find useful!
