Press release: “The fourth Mental Health Advisory Team survey, MHAT IV as this survey was called, was conducted in August and September [2006]. For the first time, the survey included Marines in the study group. The MHAT was composed of behavioral health professionals who deployed to Iraq and surveyed soldiers, Marines, health care providers, and chaplains, Army Maj. Gen. Gale Pollock, the acting surgeon general of the Army, told reporters at the Pentagon. The MHAT IV team found that not all soldiers and Marines deployed to Iraq are at equal risk for screening positive for a mental health symptom, and the level of combat is the main determining factor of a servicemember’s mental health status, Pollock said. For soldiers, deployment length and family separation were the top non-combat deployment issues, whereas Marines had fewer non-combat deployment issues, probably because of their shorter deployment periods, she said.”
