Cormac was born to a poor family in the Belfast slums, his family had always been associated with the IRA and naturally Cormac developed a deep love for his country and a deep hate for the invaders. Growing up Cormac was a very wild child always getting into trouble and fights, around the age of 14 is when he got involved with a underground knife fighting ring which is where he gets most of his scars including the nasty one on his face. Also around that time his father began introducing him into the life of being a member of the IRA, taking him to various training activates, this is where he learned how to use firearms effectively and also how to make improvised explosives, he also learned additional skills from his father that most other members don't get, he learned various methods of "information gathering" and it was these lessons that he took a real liking too. By the time he was 17 he was a full member of the IRA and took part in various operations both in Northern Ireland and in the attacks that took place in London during the early 2000s. Cormac loved doing his part for the cause, especially when it included interrogating servants of the Monarchy. He would often get... creative in his methods and often got carried away with his "interrogations" this earned him the nickname "Bloody Mac" among both his comrades and his enemies. He continued perfecting his craft as both a guerilla fighter and as a information gatherer through out the 2000s, but in early 2017 he and his comrades caught word that the British Military was on the hunt specifically for Cormac "Bloody Mac" Gallagher, and they wanted to bring him in to answer for his "war crimes" or to put him down if necessary, hearing this Gallagher's commanders decided to send him on a mission to Chernarus in late June in order to 1. Get him out of the country and 2. To secure more weapons for the eternal struggle. The job was only supposed to last a couple of months at most and then it was supposed to be back to Ireland for the freedom fighters, but God had other plans for the Irishmen. When the outbreak broke out in early July Mac and his comrades were in northern Chernarus attempting to make a deal with some Russian arms dealers and didn't have time to make it back to the airport or to the docks to catch an emergency ride out of the cursed country. Ever since then Mac has watched every single one of his comrades he arrived in Chernarus with die in horrible ways, whether it be by the hands of infected or of his fellow survivors. Now he just wanders the wastes of Chernarus offering his "services" to any who would be interested... and even to some who are not. Cormac doesn't have many defined goals at the moment besides wanting to sate his lust for seeing others suffer at his hands, and to one day return to his beloved Island.
