Jackson was born to Irish parents who, at the time of his birth resided in Birmingham, England. For the first eight years of his life that's where he grew up but following the death of Jackson's older brother the family returned home to Ireland. This uprooting of his life explains why Jackson accent is unique in it's blend of recognisable Irish overtones with an underlying hint of Birmingham for good measure. When returning to Ireland the family decided that it would be ideal to move closer to their other relatives and as such they settled on Londonderry, a town right on the border of Northern Ireland and the Republic.
Jackson was too young to remember the heyday of the IRA, though his family had felt the full effects of their devastation. As mentioned his older Brother, Filip, had passed away while the Family were still in Birmingham. It had been a cruel irony that the Irish family lost their oldest son to the 1996 Docklands bombing in London, where Filip worked. Of course furthering this irony Londonderry was a hotbed for IRA activity, though fortunately upon his return to Ireland the ceasefire was soon to be called and all of the violence would slowly wind down.
After leaving school Jackson joined the Londonderry Fire service and slowly but surely progress his way up the chain of command until such a time that he became a chief fire officer, it was while in this position in 2009 that Jackson was contacted by an official member of UN engagement on behalf of the United Kingdom, to this day the selection process and how Jackson ended up chosen is lost on him, but he was given the chance to sign on as a replacement for one of the late members of the UN's Liquidators. These men would be tasked with Nuclear and Humanitarian containment should an event transpire. The men and women of this organisation were representatives from different countries and backgrounds but all shared this one commitment.
Years of training went on before Jackson was called upon in any official capacity to full fill his role as part of the Liquidators and at a moments notice on a late evening sometime in early July 2017 he was told to collect his belongings and report to Ebrington Barracks, Derry where he would be given further instructions. Upon arrival he was briefed about the days that lay ahead but little information as to the true nature of this call was given, it wasn't until he had been flown out to mainland Europe and then on to a small black site within Russia, not far from the Chernarus border that he learned of what he was there for.
He along with a hundred or so other men and women were to enter Chernarus and aid in the containment of an unknown "plague" that had ravaged most of the country.
