  TACTICAL ASSESSMENT
  6-141. During exercises and contingencies, when time or situation prevent the completion of a full DZ
  survey, such as to support highly mobile ground forces, the using unit must at least complete a tactical DZ
  survey.
  6-142. Though using the AF IMT 3823 (discussed later in this chapter) is preferred, it is not required for
  a tactical survey. Requests and surveys may be sent electronically. As much information as practical
  should be obtained and forwarded for review. The unit sends requests for a final review of the tactical
  survey to the designated exercise or contingency airlift, or to the senior representative of the special
  operations airlift component.
  6-143. When using a tactical DZ (Table 6-11), the airlift unit assumes responsibility for aircraft safety of
  flight; the receiving unit assumes responsibility for injury to personnel or damage to equipment or air
  items. The DZ size is determined by the mode of delivery, load dispersal, and discussion with the receiving
  unit about air item recoverability and load survivability.

  INSTRUCTIONS FOR COMPLETION
  6-144. This paragraph explains how to complete AF IMT 3823, Drop Zone Survey, shown completed in
  Figures 6-20A and 6-20B (pages 6-51 and 6-52). All blocks must be completed. The completer should
  write "NA" in blocks that do not apply. When performing a safety-of-flight review on a foreign DZ, the
  completer should enter as much information as possible on AF IMT 3823. At a minimum, he must provide
  information for blocks 4D, 6A, 6B, 7, 9A-F, and 9H. He should attach a copy of the foreign DZ to the
  safety-of-flight review.
  Block 1A
  6-145. Enter DZ name.
  Block 1B
  6-146. If the survey will be sent to HQ AMC/DOTK for inclusion in the ZAR database, then enter only
  "NA." If the survey is for local use, then the group tactics office should complete this block.
