  Appendix G
  Questioning Quick Reference
  This appendix offers a quick reference for the trained HUMINT collector. It is not meant to be
  all-inclusive, nor instructive in proper questioning technique, but lays out frequently used
  requirements grouped logically by OB factor. Proper formation of questions is covered in detail
  in Chapter 9.
  Missions: Mission questioning consists of three areas: Time of Capture Mission, Future
  Mission, and Past Mission. Missions are questioned in that order, to ensure that the information
  is collected in the order of importance to a supported commander. Logical follow-up questioning
  may lead the collector into any of the OB factors at any time during questioning in order to
  provide complete information.
  Offensive Missions:
  When will the enemy attack?
  Where will they attack?
  What is the main objective of the attack?
