Lesson 5/Learning Event 2
LEARNING EVENT 2:
PROCESS CHEMICAL AND
BIOLOGICAL SURVEY DATA
Unit survey teams will report chemical and biological attack information for their unit area to the
next higher headquarters. The NBC 1 (Chemical or Biological) Report is the report used to forward
this information. NBC 1 (Chemical or Biological) Reports are forwarded through intermediate
headquarters to the NBC Element (NBCE). The NBCE is normally part of the division tactical
operations center or comparable operations center. The data needed by the NBCE to outline the
area of contamination can usually be obtained from these reports forwarded by the unit survey
teams.
When sufficient information is not available to accurately define the limits of contamination, the
NBCE can request that a chemical survey be conducted by personnel from a unit within or near the
attack location. Chemical reconnaissance personnel from the NBC Defense Company also may be
detailed to conduct a survey. The results of the survey are then forwarded to the NBCE.
As information on chemical or biological contamination is received by the NBCE, it is immediately
posted to the situation map. After all available contamination information has been posted, a
decision must be made by NBCE personnel on whether there is one large area of contamination or
several smaller ones. When sufficient information is received to delineate the contamination
boundary, the plotted points are connected with a yellow contour line to show the entire area of
contamination.
The NBC 5 (Chemical/Biological) Report is prepared from the contamination information plotted
on the situation map. This contamination information is received in the form of subsequent NBC 1
Information for the NBC 5 (Chemical/Biological) Report is also extracted from NBC 2
(Chemical/Biological) Reports. When time and distance permit, the report is best sent as a trace or
overlay; however, with the dispersion of units on the modern battlefield, the report can be
disseminated much faster in message form.
The NBC 5 (Chemical/Biological) Report consists of a heading, containing routing information, and
the body of the message, containing contamination information. The body of the message consists
of lines ALFA, SIERRA, TANGO, and XRAY.
