On the cusp of resiliency sits its darker counterbalance, mental health. It afflicts service members across a multitude of diagnostics, with one of the most common being Post Traumatic Stress Disorder (PTSD). This is where Sebastian Junger delves into a radically different approach with his book, Tribe, by assessing the fellowship and purpose of individuals within a deploying unit experience. Comparatively, there is a recorded loneliness and depression those same individuals feel when returning home, particularly when seeking to reintegrate into society. In exploring human psychology, Junger presents a phenomenon of unity and intent when people collectively engage in a cause.
