Joshua was born and raised in the U.S. by his single father, Hunter Gagne, in 1992. He lived in Kentucky so he was a bit familiar with "the hills" as southern Kentucky people called it. He and his father always went out hunting together in the hills as it was their favorite thing to do. While hunting, Hunter would always tell Joshua some of his war stories of the Gulf War. He would talk about how a US-led coalition force made up of nearly one million service personnel from 30+ countries, including 53,000 from the United Kingdom, was assembled to expel the Iraqis should diplomacy fail. Joshua always looked up to his father and was so intrigued by his stories that he wanted to be like him someday. Big, strong, and brave. Not afraid to back down from anything! His father, unfortunately, passed away from a heart attack in his sleep when Joshua was only 15 years old. From then on out, his grandparents were the ones who took care of him. Some years later, Joshua graduated high school and enlisted in the US Marines. He was then shipped to reinforce and help assist in the US War in Afghanistan in 2012. In October 2014, British forces handed over the last bases in Helmand to the Afghan military, officially ending their combat operations in the war. In December 2014, NATO formally ended ISAF combat operations in Afghanistan and officially transferred full security responsibility to the Afghan government. The NATO-led Operation Resolute Support was formed the same day as a successor to ISAF. In 2017, Joshua was apart of the garrison deployed in Elektrozavodsk, Chernarus after the outbreak occurred.
