(3) Relocation of the chain link barrier fence soutri of the DFLZis planned in five areas in order to take maximum advanrtae of terrainoffering the best observation, and where *,ossible to move fightingpositions out of low lying rice paddy areas, helocation of the fence inthe first area was completed during tiis reporting period. forK becanon 15 September 1969 on the priority two area. The priority two fencerelocation project is now 17M completed. In additioni construc't•un of P

(4) Effective 2•3 September 1969, A Company, 2d Aviation battalior.was released from attachment to FASCOM and returned to the opera.tionalcontrol of 2d Infantry Division. To provide adequate space for the unit,redistribution of facilities at Stanton Army Airfield -.i; r- iuirel. Kd-ditional administrative, maintetianco, billetiii, ant aircraft par~ingspace resources were identified, and critical faciLities were re-allocate]to ensure utilization to full capacity. The relocation of the unit toStanton Array Airfield was com)ý.eted on 31 October 1969. L'he return ofA Uompany provides the 2d Infantry Division with orp-anic 1iH-I aircraft andbroadens the scope of aviation support available for traininL and operatior'Al

reqiuirements. Aviation assets assigned to the 2d Infantry Jivision have nowincre.Aued to 19 OH-23 and 12 UH-1 helicopters. All fixed-wing aircraftwere transferred from the Division to provide facilities to accomodatethe additional UH-1 aircraft at Stanton Army Airfield, now closed tofixed-wing traffic except during emergencies or hostilities.

(5) During September and October, the Division Aviation Officerplanned and supervisei three CH-47 helicopter missions involving emplace-ment of pre-formed concrete foxholes along the barrier fence. A totalof 14 of these foxholes were emplaced in areas not easily accessible byground transportation.

(6) In the 2d Div sector of the DMZ on 18 October 19o9, four USpersonnel assigned to 1-32d Inf (7th lnf Div Rotational Bn O01%.,1J to 2dInf Uiv) were ambushed and killed by a team of four hostile individ ialswhile returning from Guard Post Turner. It is apparent that this wasa deliberately pre-planned act ratrier than an ambush of opport.unity aridthat the incident may be a prelude to increased Communist activity inthe demilitarized zone.

(I) Ubservation: This comrmrand is informed on a monrthly basis ofprojected officer assignments and in many cases names an1i hTit of theincoming officers are furnished. This information is t enr used b. theDivision to project forthcoming assignments an, by name fills. Insome instances officers do not arrive as forecast with rno aivance informaiaonto this headquarters of changes being made.

(2) Evaluation: Due to the present shortaLe of offi::irs in the2d Infantry Division, particularly in the& grade of Ca,.taizi and riajor andin Field Artillery and Armor Lieutenants, the lack of advanced noticeof officers not arrivitn, on schedule cal.ses unnecessary turbulence.

(3) Recommendation: That efforts be made by EUSA and Department ofthe Army to inform subordinate commands when forecast officer replace-merits are delayed or receive changes of orders.

b. Operations:

(I) Minefield Clearing with Tank kollers:

(a) Observations: Approximately 75, of all mines detonated by theuse of tanks with mine clearing expendable roller, model 1A were detonatedby the tank treads rather than by the roller. Problems were also experier cedwith the roller becoming entangled in barbed wire an:1 other entauijlemernts.

(b) Evaluation: While the tank mine roller is effectivu in clearingroads, it is only partially effective in rough or brushy tarrain. Tanksoperating without rollers are more effective under these conditions astheir maneuverability is not hampered by the rollers.

(c) Recommendation: That the tank roller be used onl, on flat level

terrain which is clear of obstacles.

(2) Minefield Anti-Blast Boots:

(a) Observation: Since mine clearing operations were begun inNovember 1963, to clear the estimated 59,k=XO mines located! in the vicinity

(b) Evaluation: A barrier lighting system will incre;tse the eiffective-ness of night observation equipment and will permit continuoub visualsurveillance of the barrier system during the hours of darkness increasingthe effectiveness of detection of Worth Korean agents atteapting to cro'ý;th e lighted area. A two kilometer section of lighting has oseri izstalledfor evaluation in the 2d Infantry Division sector.

(c) Recommendations:

1 That a complete lighting system be designed and installed alongthe 2d Infantry Division barrier fence.

2 That the use of barrier lighting systems be considered along theDITZ In other areas of Korea.

c. Training: None.

d. Intelligence: None.

(I) Data Link Circuits:

(a) Observation: During UPX FOCUS IEWS it was noted that data linkswere not provided between FASCOR agencies and the 2d Infantry DivisionSupport Command. During garrison operations, two data links are operationalon a daily basis, one between the 2d Supply anl Transportation Battalionand the Inventory Management Center (124C) in Taegu, and one between the702d Maintenance Battalion and the 457th Replacement Parts Company inUijongbu. At the present time these circuits are pas-'ed over the garrisontelephone system.
