Testament of 'an honest man and a soldier'

Whether you call it battle fatigue, shell shock, PTSD (posttraumatic stress disorder) or OSI (operational stress injury), the mental trauma that can occur in conflict areas is still barely understood. It is often governed, particularly in the military, by ignorance and hidden by a culture of macho denial. Why some are affected, while others remain apparently uninjured, by the same circumstances remains largely a mystery.
