The Civil Affairs section that Hargrove is assigned to is a real military department.
The purpose of civil affairs is to work with the civilian government, or where civilian government is absent, to act in place of it, in countries where the U. S. military operates. The goal is to help restore civilian order, rule of law, and effective government operation, all while reducing resistance to the military presence.
