ARRANGEMENTS FOR OOMINT DISS.Etam.TION TO AND WITHIN 

SHAPE AND ITS SUB-COMMANOO 

I RESPONSIBILITY FOR DISSEl'IINATION 

1. The Office of the Assistant Chief of Staff, G-2, Department of the 

Army and G.C.H.,. will serve as executive agents for u.s.O.I.B. and L.S.I.B. 

respectively for service of Comint to S.H.A.P. E. and its Sub-Commands. · 

2. In order to provide for close co-ordination in the dissemination 

of U.S. and U.K. Comint to S.H.A.P.E. and its Sub-Commands, G-2, D/A will 

establish liaison at G.C.H.Q. 

II PRINCIPLES OF DISS:&dINATION 

3. a) Rear to Front 

(i) The principle of direct simultaneous dissemination of Comint 

to S.H.A..P. E. and its Sub-Camnands in war-time is agreed. It 

is also agreed that it is essential to achieve in peaca-time 

the methods which \vill be required in war. Initially in peace, h~·;ever, not all of S.H • .i:i-.P. E. 's Sub-Commands are in a state 

of readiness to receive a direct service. Therefore, initially, 

only critical itt:tms will be disseminated directly to Subcommands, tho remainder being disseminated to them by S.H.&.P.E., 

which will inform G-2 and G.C.H.f.c:. what material is so disseniinatod. When and as determined by S.H.l;..P.E. f01• each SubCommand, routine direct dissemination from executive agents 

to S.H.A.P. 'E. Sub-Commands will be initiated. S.H.A.P.E. \vill 

in all cas&s receive copies of all Comint disseminated directly 

to its Sub-Cormnand.s. 

(ii) \'/hen direct dissemination to Sub-Commands begins, S.H.li..P.E. w~.11 establish the requirements of its Sub-Commands. 

(iii) Within the foregoing limits, U.S~ and U.K. produced Comint 

will be disseminated directly by the respective executive 

agents to S.H.l ... P. ~. and its Sub-Commands by the most expeditious means available to either party. The executive agents 

will exchange all Comint disseminated by them to S. H • .i.~.P. E. 

and its Sub-Commands by the most expeditious means available. 

/b) Front to Rear

Front to Rear 

(i) as a principle, . front ·to rear dissemination normally should 

parallel Command channels, with exception being made for items 

of a critical nature. S.H • .H..P. E. will determine which of 

existing Comint canmunioation channels shall be employed until 

facilities for dissemination in parallel with Command channels 

are provided. 

(ii) S.H.~.P.E. will d~termine the r~quirements and responsibilities 

of the Sub-Commands. 

(iii) With the cognizance of the executive agents, S.H.~.P.E. will 

arrange with the appropriate U.S. and U.K. national authorities 

to obtain for itself and its Sue-Commands material produced. 

by U.S. and U.K. field Comint organisations outside the S.H.k.P.E. 

Command structure. 

(iv) It is agreed that any rear to front Canint material incorporated 

in front to rear reports should, so far as practicable, be 

clearly indicated as such. 

III DISS:D:i.I~IiLTION STRUCTURE 

4.. In order to provide adequate Comint channels, the Eii (SIGit.:&), 

subject to approval by the London Cypher Policy Board, will be adopted initially 

as the combined cypher machine for combined use in the dissemination of Comint 

to S.H • .A.P.E. and its Sub-COJTimands. This does not exclude the use of other 

approved systems in addition to ECM.. As soon as possible, G.C.H.Q. Will provide a land-line "on-line" cypher system between G.C.H.Q. and S.H • .t...P.E. 

subject to approval by U.S. communication security authorities. "On-line" 

radio facilities linking G.C.H.Q. and N.S.h. are available for use and will 

be used insofar as they prove the most expeditious means of transmission. 

N.S.A.. and G.C.H.Q. will give Camint for S.H • .ti..P.E. and its Sub-Commands 

priority in each category of precedence. The question of using for this 

purpose in peace-time one of tho en1&rgenoy cable channels between N.S • .A. and 

G.C.H.Q., to obviate delays due to bad transatlantio radio conditions, should 

be considered by the appropriate authorities. 

S. It is agreed that the EDivl will be made available for installation 

at the following organisations and Commands:
