N 1515 

M/R: Paragraph IV.C.l.h. of DOD Directives 3115.2 and 3115.4 each 

states that 11The Secretaries of the Military Departments will: state 

to the Director, XSA, their requirements for ELIIT ( 3115. 2), C<JaNT 

(3115.4) direct support.• 

NSA letter, Ser N4o52, Subj: Delegation of Operational. Control {U), 

dated 10 October 1959 reviews original delegation (NSA letter, 

Ser 000307-s, Subj; COMDJT Close Support Bequirem.ents of tbe Department 

of Arary, dated 29 May 1953) of facilities to J)e.pt of Army tor "close" 

support. The latter reference states that original delegation is no 

longer valid due to change structure ot' units involved and increased 

dual responsibility of service units for direct support and general 

support to national SIGINT effort. Further, Director, BSA, expresses 

in this reference tbat 29 May 1953 letter is to be superseded and 

delegation of direct support requirements for CG, Seventh and Eighth 

Armies will be incorporated in MUSSO ( OPIIS-1 and/ or 10), as appropriate. 

ACSI DA. Letter, Subj: Delegation of Operational Control (U), dated 

12 ~ 1960 states Dept Arm:! requirements for SIGIBT direct support for 

Seventh and Eighth Armies by listing in detail all positions and organizations. Many" of these positions and organizations to which they belong 

are theater support elements, i.e., 28oth USASA Co. (ill support of USCOB, 

a component of USARiUR--not Seventh Army). 

ACSI DA Letter, Subj: Delegation of Opere.tional Control (U), dated 

28 JuJ.y l96o and the basic letter to this correspondence confirm these 

requirements. 

On 25 May 1960, conference was conducted to attempt clarification of the 

stated ACSI DA requirements. Representatives or NSA1 ACSl Dt\. and USASIL 

were present (quote from Memo for the Record prepared by USASA representative follows) • 

"Mr. Winkler (ACSI Rep) and the undersigned (LtCol Rolle, USASA Rep) 

stated that if ACSI and USASA representatives could receive 

1nf'ormal. written queries concerning matters in the ACSI J.etter on 

which PROD-04 desired clarification, ACSI and USASA coulcl expeditiou.sly obtain ACSI/USASA replies thereto. PROD-04 representatives 

agreed to this procedure.

M/R: (Continued) 

It was noted that instant action was first US Army statement of 

direct support requirements. It wu noted that DI.mi& retains 

tasking authority, through !l1SSO cbannel.81 of SIGDIT units, even 

those released to operational control of Chief', USA.SA. USASA 

representative pointed out tbat this tasking authority was understood and poaed no particular problems. 

Careful reading of the ACS! letter discloses no direct request for 

delegation of operational control of the units and positions listed 

in Inclosure A (sic) of letter, though it is implied that operational 

control is desired. It is anticipa'ted tb&t DIRNSA will non-concur 

in delegation of' operational control to the extent indicated, 

especially since DIRISA's representatives feel that J111n7 listed 

positions are not presently utilized solely or primarily 1n direct 

support." 

As a result of' meeting, ACSI (Mr. Winkler) was informally requested on 

3 June, by NSA: 

"We are assuming that stated "present requirements" for direct support 

are pee.cetime requirements (and that the positions involved will 

continue to be subject to Director, JfSA, tasking throu&h OPDS-10 

as at present) and that they represent al.so the general var direct 

support requirements of these armies as of M-Day. In connection 

with any statement of general war requirements, it is presumed you 

desire that positions requested wi.ll be subject exclusively to the 

tasking authority o£ USA.SA or its subordinate echeJ.ons. You will 

understand that, if this presumption is correct, BSA 111U&t consider 

Army requirements in conjunction with those of' the other military 

departments in order to determine whether or not there will remain 

a sufficient number of positions of' specific types to :t'ul:t'ill the 

needs of direct service and national (USIB member) requirements in 

time of war. 

It is noted that ref'erence provides for forwarding these requirements from CG, Seventh and Eighth Armies to the unified commander, 

apparently bypassing the theater's Arta::i component cC)Dlll!Ander. In 

this general regard, the question is raised, insofar aa tbe Pacific 

area is concerned, whether or not other Army forces 1n that theater 

reqllire direct support, e.g., forces at Oahu."
