A syslem for requisiticx.•ig should show by month the authorized, assigned,projected losses based on DEROS, gains projected through requisition and totalnumber of personnel which shorld be on hand for each 110S authorizeed in theorganizationo At the end of each mont:i, fill action on each SOSC for the pre-ceding month should be entered in parenthesis beside the total requisition.Fill action for the past three months prcceitng the current requisition monthwould justify the necessity fo: an eer&•ricy requisition in cases of a short-fall. Utilizing the above procedures uould pzc~vide irr.ci.ate response forproper assignnmnt actions and present a picture of projected strength based onthe requisition cycle.

(2) Reqairements for Cable Splicers.

(a) Observation: The requirement for school trained cable splicers Willcontinue to increase.

(b) Evaluation: Althourh the z!taubcr of new outside plant cable construc-"tion projects has decreased., thl num~ber of cable rehabilitation projects hasgreatly increased. These ;u--ejects require an increcsed effort of cable splicers.The amount of money saved in. rehabilitating cable as opposed to installing newcable warrant and justify the rehabilitation effort.

b. Intelligence:. None.

c. Operations: Splicing Multipair Polyethelem Insulated (PIC) Commini-cations Cable*

(1) Observation: There is generally a lack of quality assuran.e in cables-1icing operations. This is evidenced by numerous instances of iproperlymade splices and splice cases which are improperly sealed, allowing water topermeate the "ablae

(2) Evaluation! The number of co:a•unications cable that have become vetor which have become degraded because of loTw insulation resistahce has beenexcessive. The major reason for splices becozing wet is that improper tech-niques have been used in sealing the splice cases. In many cases. due to alack of certain items of material, splice cases were closed without being"watertight. With added supervision of the project and inspection of work at

Additionally, monitoring of theproject by those personnel that will eventually have to maintain the cable willinsure that they are familiar with the installation and discoTer unacceptablecable construction practices before it is too late.

(3) Recomeendation: That all units pl.ace additional emphasis on supervisionof cable construction in addition to closely inspecting critical phases ofsplicing prior to encasing cable or burying it in the grounde A ist SignalBrigado Regulation governing cable construction has been re-written to placeadditional emphasis on testing of cable in addition to requiring that units in-sure project supervisors inspect cable projects during critical phases ofinstallation.

d. Organization: Need to consolidate communications - electronics missionsunder a single manager at a major headquarters.

(1) Observation: 1MATV 1 ±eadquarters Compoand was serviced vith itscommunications -' electronics needs by various units of the 690U, 369th, andPhu Lam Signal Battalions, This caused coordination problems and restoralproblems during rajor catastrophe communications failures.

(2) Evaluation: Each element responsible for co mnrnications-electronicsM13slons at tne A.UV compound was responsive and pronessionai in its own area*In event of a major failure such as a MACV Compound power failure, confusionas to restoral priorities of areas, systems/circuits became apparent. Eachelement was responsible to its parent unit, with overall coordination beingslow and non-responsive.

(3) Recommendation: MACV Headquarters Compound now has overall coordi-nation vested in one individual, titled MACV Headquarters Signal Officer (HSO).in this case, the CO, 69th Signal Battalion has been designated HSO and isresponsive to the IIACV J6 for all communications-electronics operating elementsat the 4ACV Headquarters, Operational control of all operating elements havebeen assumed by the HSO.

(b) Evaluation: Under normral circuristances radio relay sites could beestablished to eliminate extended line-'of-.aight (LOS) cyatoms. However, vith-in Vietnam this is not feasible in many cases due to insecure areas betweeninstallationso T- establ13h a radio relay sits wouLd rnquire at least acompany size unit to secure it. plus the logistical problem encounteredo Thisapproach is not practical from either an ec.-,nomizal or manpower point of view.

(c) Recommendation. In order to overcm.oe the above situation, AN/TRC-29parabolic antennas have been employed with the '1 /GRC'50 radios to provideneeded gain for reliable system. The AsTRC•29 provides por ci.tately 30 dbgain at t-, center frequency of 2000 1. Its efficiency is lcered consider-

* ably vhen operating it below the lower li--.its of 1750 1-0s The MGO,50 Antennais broad banCled to cover the large rangs of trequencies and at center frcq-zyit provides approximately 18 db gain. The beam width of the signal is alsoincreased when using the TPRC29 anterrna on lowsr frequencies. To deterzrdmsexactly what benefits the TRC-29 antenna rrovidaeover the GRC>50 it is re-ccnmended that aditional te'b be made i~e.o V57R over the frequency range,field strength measuremsnte,- lwt-a.n width, etc.

have dictated that circuit• be called up on very short notice, not allowingsufficient time to issui the TSO3 order and receive MA.TSYMS in the requiredtime frame,
