.3.  HEADQUARTERS  f  US  AS  A.  Heads  of  Staff  elements  concerned  will  maintain 
staff  supervision  end  guidance  over  the  15ASA  worldwide  DF  programs  through 
review  of  selected  technical  end  operational  Information  provided  by  field 
activities.  In  addition,  necessary  liaison  and  studies  will  be  conducted 
to  insure  that  the  programs  remain  abreast  of  the  advancing  technical 
tciences. 
6.  SUBORDINATE  ELEMENTS.  Each  USASA  field  element  having  DF  will  be 
responsible  for  the  control,  processing,  evaluation  and  reporting  of  the 
efforts  employed*  The  day-to-day  operation  and  timely  recognition  and 
correction  to  problem  areas  are  the  responsibility  of  the  field  elements. 
When  problems  Identified  are  beyond  the  capabilities  of  field  elements, 
to  correct,  assistance  Is  to  be  requested  from  this  Headquarters. 
* 
7.  LIAISON  VISITS.  DF  representatives  froa  this  Headquarters  will  visit 
each  DF  control,  DF  tasker  and  each  DF  outstation  at  least  once  each  fiscal 
year.  The  DF  met  control  officer  Is  responsible  for  the  technical,  operational 
and  tasking  control  of  all  DF  sites  ^i-iia  the  net.  Therefore,  he  and/or  the 
DF  net  control  NCOIC  will  visit  every  outstation  In  the  net  at  least  once 
every  three  months.  If  a  SIT  technician  (W0V  MQS  0S3A)  Is  assigned  to  the 
parent  organisation  of  a  DF  site,  the  SIT  technician  and/or  his  NCOIC  will 
visit  each  subordinate  DF  site  on  a  monthly  basis  to  perform  a  technical 
Inspection  of  the  site  and  provide  assistance  as  required*.  When  problems 
concerning  performance  of  outstetions  arise,  net  control  will  advise  the 
parent  organisation  of  the  DF  site  and  *lll  also  provide  technical  aaslstance 
as  required  to  correct  the  problem.
