[Tentative for Livonia]
Martin grew up in America, later being joining a security company for low-level guard duties for a pharmaceutical corporation which led to his recruitment to a cooperative effort between several nations and businesses intended to mitigate some of the effects of the ongoing apocalypse early into the crisis. Sadly, the group was mostly filled with token contributions and served little use and effect to it's original intention, instead being a front for more questionable activities.
Martin's purpose was mostly to gather and report intelligence from Europe to his american-led employers. After contact fell through early in the crisis, he decided to stay in his area of responsibility and use what few contacts he had left to bide his time until travel back to America was both available and preferable.
