Quinn is an experienced Sergeant, who has spent longer in His Majesty's Marines than he has spent in the Royal Marines, simply due to his enlisting at a young age, before most of the men under his charge were even born.
His service at sea began quickly when he was sent to join HMS Crescent, 28, and he was aboard during the frigate's brief service in the Mediterranean. Shortly after the Action of 30 May 1781, Crescent was captured by the French and Quinn spent the next two years as a prisoner of war.
He tempers discipline with patience and a willingness to work with his Marines to help them learn and progress.
He is currently an NPC.
