John Stone is/was apart of a discrete task force inserted into Chernarus by the U.S. military with a purpose of a means to an end. His task was to find the source and cause of this outbreak from a base located north of Severograd which was leaked to them by a reconnaissance team previously dispatched to monitor military movement/strange activity in the area. There were rumors.. Some of which overheard, but almost all information redacted from any reports which were given to me... I was to embed myself in the area and learn as much as I could. I'd have little to no contact with any outside support as the possible material was too valuable to trust with anyone else not assigned on this mission. I was told to regroup with the wave of reinforcements that was supposed to arrive and setup a research facility and deliver my findings to a major and a key U.S. researcher. That was my mission, what they'd do with that information is unclear... As it'll remain that way.
