....... ~~-----~~~~~~~~~~~~----..---~~~~~~~·-·~~~~~~--- Special Intelligence involves a unio::!lle security problem, which arises 

from the fact that the source exists ~nly because, and only su long as, 

the other countries believe it NOT to exist. Once they suspect 'Chat 

a special Intolligence suurce has been succassfully tapped, it lies 

within their power tu close it off instantly. Therefore, the misuse 

of a single pieoe of Special Intelligence info:nnation, especially 

inf..:.rmo.tL·n nut easil~r ubtainable from other suur<Jes, is likely to 

cut off the source, nut unly of that particulsr ty:ie of ~nformatiun, 

but of much uther ·v·aluable information a.s well. Cvmmunications 

Intelligence is intelligence pruduced by· a study of com.-nunications 

r; not uriginated by United States Authc,rities. This fact must be I teitally safe~arded. 

I, the n~do~sie;ned, undorsta.~d the provisions ui' AFR 205-1 and D.A.F 

Regulations for the Security and D:i.sserr.inatiun uf CO!.'I!~T and that 

no portiu11 uf this dc.ioument may be disclused to eny persune not 

indoctrinated and cleBred fur access to CO!.D:NT.

4. The revised indicators· are oriented toward the devel~ment ot 

Soviet capabill'Ey tor atr at'EiCk upon flhe UD!'Eed S'Ea'Eea andard the 

1D!tlati1m of gen-erat hostllitlea. This in no way negates the accept= ability of report& ot 1Dtent. X:E is the opinion or the Indications 

Camaittee, however, tha'E the state ot Soviet intentions may be logical.17 assessed from the nature or and emphasis an the c~~abilities 

developed. This has been Ciearlj' demonstrated durtng ore first six 

monhlis ol the existence ot the Indications Board. During this period 

onl.7 one report (F-6) or intent was received.; the conditions forecast 

by thi• report have not been met, and its validity cannot be assessed. 

The development of Sovi"et and Satellite capabilities and the trend 

_.,stabliahed by. thsir actions forms the most logical basis for deduc- ' 

tions o:t future actions under any given set 0:£ comitions. 

. S. The original set or indicators, together with a copy of the 

record photo ot the Indications Board £or period 1 January 19S2 to · 30 June 19S2 are also inclosed for ce>q>arative piuposes. Comments or
