Having served in Army for most of his adult life, he was stationed in Germany as a Master Sergeant when news of what was occurring in Chernarus had reached him. Being apart of the US Army NATO division, he was unsurprised when the people under his command were rallied, and they were told they would be there not only to stem the outbreak of violence but to hopefully assist with any efforts in organizing the uninfected. When they had arrived, he was not prepared for what he was witnessing, and what he was going to be witnessing in the future.
What happened within the two days of their arrival stunned even him, and as he and his men were forced to flee from a tide of creatures that were once human, he was realizing the gravity of the situation, and what was worse, he and his men were cut off from the extraction teams that had been meagerly set up. It was a saving grace, perhaps, as it was not long after that he found their extraction point had been overrun.
Electing to take what surviving men he had up towards the Air Base in the hopes of consolidating with air and ground forces there, he was met with another disappointment. The highways were blocked by panicked people, news of the infection having spread into the outlying countries was at the top of the News tickers, and he was left in a foreign country with his men, stranded by both panic and incompetence of Top Brass.
Most of his men succumbed to the cold, to illness, and infection, he is the only one to survive, by some cruel grace of God.
