Use all means of nuclear, biological, and
chemical (NBC) detection to check your surrounding
area for the presence of contamination.
Contact your higher headquarters (HQ) if no
contamination is found or if you determine the
attack was non-NBC.
Await further guidance. (The higher HQ contacts
all adjacent/attached units to check the status
of NBC contamination in their areas. If all units report the absence of contamination,
the information is reported up the chain of command).
Annotate the above actions on your duty log
(DA Form 1594).
