as  an  interpretation  of  SM  435-73,  the  text  of  which  is  pro- 
vided as  Annex  A  to  this  directive.   Annex  A  should  be  reviewed 
in  its  entirety  to  assist  in  understanding  command  recuests  for 
support  and  to  facilitate  proper  response  to  them.   SIGINT 
activities  are  to  "forward  queries  for  clarification  or  interpre-

requirements,  the  USSS  will -play  a  positive  role  in  peacetime 
exercises.   Realism  will  be  the  governing  principle.   Partici-

participation  of  SIGINT  resources  may  be  treated  as  field  train- 
ing, and  arrangements  for  participation  made  through  service 
channels.   Similar  provisions  pertain  to  the  use  of  prepositioned 
SIGINT  direct  support  resources  in  exercises  sponsored  by  uni- 
fied and  specified  commands.   However,  SIGINT  tasks  currently 
assigned  to  these  resources  will  not  be  curtailed  without  the 
prior  approval  of  the  Director,  US  A/Chief ,  CSS.   (See  Annex  A,

local  commandars  to  notify  them  of  the  need  for  SIGINT  involve- 
ment in  an  exercise  well  in  advance  of  the  exercise  period.   The 
Director,  NS A/Chief,  CSS  will,  in  conjunction  with  the  commanders 
concerned,  arrange,  for  SIGINT  support  to  command  exercises.   He 
will  determine  the  extent  of  the  support  to  be  provided,  designate 
which  SIGINT  resources  are  to  be  used,  and  issue  instructions 
governing  USSS  involvement.

SECTION  1  -  PURPOSE  AND  SCOPE 
1.   (U)  The  purpose  of  this  concept  is  to  establish  doc- 
trine and  procedures  for  providing  signals  intelligence  (SIGINT'. 
support  to  military  commanders  in  all  circumstances  under  which 
military  forces  are  expected  to  be  'employed.   The  concept 
applies  to  those  SIGINT  resources  which  are  included  within  the 
Consolidated  Cryptologic  Program  (CCP)  and  to  those  resources 
which  have  been  specifically  designated  as  SIGINT  activities  by 
the  Secretary  of  Defense,  wherever  programmed.   Planning  for 
SIGINT  support  to  military  commanders  will  be  in  consonance  witl 
this  concept.

intelligence  information  derived  from  foreign  noncommunications, 
electromagnetic  radiations  emanating  from  other  than  atomic 
detonation  or  radioactive  sources.   ELINT  is  produced  by  the 
collection  (observation  and  recording)  and  the  processir. ^  for 
subsequent  intelligence  purposes  of  that  information.

direction  of  SIGINT  activities,  including  tasking  and  allocation 
of  effort,  and  the  authoritative  prescription  of  those  uniform 
techniques  and  standards  by  which  SIGINT  information  is  collect- 
ed, processed,  and  reported. 
7.  (U)  SIGINT  Operational*  Tasking  -  The  authoritative 
operational  direction  of  and  direct  levying  of  SIGINT  informa-

resources.   These  requirements  are  directive,  irrespective  of 
other  priorities,  and  are  conditioned  only  by  the  capability  of 
those  resources  to  produce  such  information.   Operational 
tasking  includes  authority  to  deploy  and  redeploy  all  or  apart  of 
authority  has  been  delegated. 
8.  (U)  SIGINT  Support  -  The  provision  of  SIGINT  to  a 
command  or  other  user  or  organization  in  response  to  operational 
needs  and  intelligence  requirements.   SIGINT  support  may  be 
accomplished  by  SIGINT  direct  service  or  SIGINT  direct  support, 
or  both.

which,  in  the  judgment  of  the  commander  of  the  appropriate  uni-

described  in  paragraph  '23  preceding,  dedication  of  specific
