Dustin "Dusty" Mayfire was born in Minneapolis, Minnesota in the United States of America. Growing up in Minnesota and in such close proximity to Canada, Dusty was an avid hockey player in his youth. He was never very big or strong, but what he lacked in size, he made up for in speed and smarts. He had great vision out on the ice, and was a great leader. He played all through his youth, and first started skating at the age of four years old. He played in high school and even made the varsity hockey team. At one point it was looking like he could potentially play hockey for a top rated college, the University of Minnesota. That had always been his dream; to play hockey for the U of M. However, after his uncle died while serving in Iraq, Dusty decided that his life must take a different path. When he turned 18, he enlisted in the army and began basic training. Eventually, he was sent to Afghanistan to serve his country. The military life was difficult and frustrating, but Dusty loved every minute of it. He thrived in that lifestyle, and it served him well. He was seen as a strong leader among his comrades, and they respected him.
After finishing his tour in Afghanistan, Dusty returned home and became a police officer. He didn't really enjoy his work as a police officer; it felt tedious and boring compared to his work in Afghanistan. That's when he was hired on by a promising private military contracting company. It sent him out into the world again, and put him situations where he would yet again thrive. Eventually he was chosen as the team leader for a job in Chernarus. There was some weird virus type thing spreading around there, but that didn't matter to Dusty. It was another new and exciting adventure for Dusty.
