9-159. The assistant chief of staff, civil affairs operations (G-9 [S-9]) ensures each war-gamed COA effectively integrates civil considerations (the “C” of METT-TC). The civil affairs operations officer considers not only tactical issues but also sustainment issues. This officer assesses how operations affect civilians and estimates the requirements for essential stability tasks commanders might have to undertake based on the ability of the unified action partners. Host-nation support and care of dislocated civilians are of particular concern. The civil affairs operations officer’s analysis considers how operations affect public order and safety, the potential for disaster relief requirements, noncombatant evacuation operations, emergency services, and the protection of culturally significant sites. This officer provides feedback on how the culture in the area of operations affects each COA. If the unit lacks an assigned civil affairs officer, the commander assigns these responsibilities to another staff member.
