A poor city kid from Houston Texas, surviving the apocalypse in Chernarus is not as uncommon a story as one might think. America had vested interest in the area prior to the collapse of modern civilization. American intelligence had long since predicted the revolution in Chernarus, and had plenty of assets in the area. The Central Intelligence Agency, or the 'alphabet boys', as they were colloquially known by the Army Special Forces Detachments , or SFODs for short.
Jack Bishop joined the military at age 17 in 2012. Straight into a Special Forces pipeline. After completion of all of the grueling training and schools, he was sent to Ft. Lewis - Washington. Shortly after, he was deployed to Chernarus, to help with the rebuilding of the country, as well as counter insurgency. Every deployment for him between the years 2013-2017, those four years, he spent doing 9 month rotations in Chernarus. When the outbreak happened, he had been with his team. Like most people during the outbreak, they stuck together through most of it. However, even the bonds of military training and years of friendship and firefights were not enough to hold the team together. Like a sick war of attrition, the team started to decompose. Infection, bandits, one by one they were picked apart, two of his own had died from suicide, until at last, the very last surviving member of their team was Jack.
After survivng the decimation of his team, the last surviving member, Jack, after being robbed by bandits, blindfolded, and dragged to the coast, left for dead, wakes up, and gets a restart on the apocalypse.
