AOC 70H Course Practice Test 2026 – Complete Prep for Health Services Ops and Intelligence

Combat Operational Stress Control is the Army’s program for preventing and managing stress reactions at the unit level, handled by trained mental health personnel embedded with medical support. In field units, this function lives in the Mental Health Section of the Brigade Support Medical Company. That section houses the staff who run COSC, provide counseling and early intervention, and coordinate with leaders to identify soldiers who need help and get them into appropriate care. The other options don’t fit because COSC is not a general medical/logistics unit task nor a separate detachment; it’s a mental health capability tied to the BSMC’s mental health section, designed to keep troops ready and resilient.
