They capture information before Soldiers forget it. Higher headquarters personnel normally perform these debriefs. Mission debriefs may include all unit members and attached personnel, especially at the lowest echelons. Higher echelon debriefs may include only unit leaders. Normally, mission debriefs are oral. Sometimes a written report is required. Information in written reports should include: size and composition of the unit conducting the operation; mission statement, including the form of maneuver or task (for example, patrol, raid), location, and purpose; departure and return times, routes used; detailed description of the terrain and enemy and civilian activities; results of any contact; and personnel and equipment status at the end of the operation.
