Enemy activity wa, mostly limited to ;::ailpatrol contacts, light standoff attacks, and the harassment of convoys andfriendly villages. The 4th Inf Base Camp, Camp Enarl, was not fired upon orprobed by enemy elements during the reporting period. This was attributed Loagaressible patrolling and aerial observation.

The 1st Bde was alerted for a possible ,n veto Ban He Thuot to relieve local ARVN elements destined for the Bu Prang/)uc Laparea. On 11 November headquarters elements cf Ist Brigade and 6-29th krtillerymoved to Ban Me Thuot, and a combination concy/airlift moved 1-14th Inf and2-35th Inf with DS BAtteries (A/2-9 and B/2-9) to Ban He Thuot East. A/2-9Artillery and two tubes from B/2-9 Artillery moved into fire bases to the northeastand souta of Ban Me Thuoto D/2-320 Artillery, DS to 3-506th Infantry, locatedeast of Ban Me Thuot at FSB Chu Kuk (BQ226167), became OPCON 6-29th Artilleryon 12 November. The operation began with elements of the 1-14th Infantry and 2- 5Infantry conducting search and clear operations and 3-506th Infantry continuingsecurity of QL 21 east of Ban Me Thuot. Several swall contacts were made in tcw1-14th Infantry AO during November. However, in most cases the enemy chose toevade rather than fight. Intelligence indicated that elements of the 401stSapper Bn were located in the vicinity of Hill 701 (AQ 9131) and the 1-14th Infbegan a new operation in that area on 2 December. Two companies moved in fromthe SE and SW while the 3rd company moved into blocking positions from the north.Artillery fires were employed on hard targets and likely avenues of a.-proacl.CS munitions were fired into pre-selected areas with HE following approximately5-15 minutes later. Three sivarate eney contacts were made on 7 December, nearthe Mewal Plantation. A/2-9 Artillery supported the operation with blocking andinterdiction fires. On 9 December 1969, emphasis was shifted to the 2-35th InfAO with a turee company search and destroy mission aloR3 the Dak Krong Ea River.The operption was directed against enemy elements thought to be in the area.Three tubes of B/2-9th ;'itillery were moved from BMT-E to LZ Blue (AP 783868) on9 December to provide fire support. This area proved to be the most profitable ofthe Ban Me Thuot ouarations. Several small contacts netted 13 enemy KIA and 1CIA. The enemy indicated numerous enemy KIA by artillery. On 16 December C Cc,2-35th Inf made a significant find which I.ncluded 60mm and 82mm mortar rounds,B-401s, hand grenades, TNT, and 107mm rckets. Operation Wayne Rock was ter-minated and all maneuver and support elements moved into BMT-E 29 December andsubsequently, by air and convoy to Camp Enari and Camp Radcliff on 30 December.

(b) Operation Wayne Thrust (4 January - 30 January): Operation Wayne Thrustwas initiated on 4 January and directed at the destruction of the Cia LaiRegiment northwest of kn Khe and the 18th Regiment west of LZ Hardtimeso By3 Jan 70, four infantry battalions and one air cav squad (-) with supportingartillery under the control of the 1st Bde -were staged at Camp Radcliff forinsertion into their respective AO's on 4 J~a 70. An attack on the CIDG base atHardtimes (Vanh Thanh) by an estimated two NVA/VC companies on 4 January causedan immediate readjustment of the operation. The 1-8th Infantry with C/6-29thArtillery and C/5-16th Artillery moved to Hardtimes to thwart the enemy threat.A/6-29th Artillery moved overland to FSB Emelia (BR 477595) to provide firesupport for the 3-8 Infantry operations in that area on 8 and 9 Janoary 1970.The 2-3'th Infantry with B/2-9 Artillery airlifted to FSB Armageddon (BR 420645)

The operation of the Ist Bde began to shift to the northeast of Af.Khe and eventually will center in the "Crows Foot" area vicinity BR 800901).

(2) During the reporting period the 4th Bn, 42d Arty (DS 2d Bde, 4th InfDiv) supported the following operations: Operation Putnam Cougar, 22 Sep - 27Oct 1969; Operation Putnam Wildcat, 2 Nov 69 - 18 Jan 70w; Operation PutnamPower, 21 - 30 Jan 70.

(a) In November 1969 the 2d Bde assumed operational control of the An LaoValley area and conducted operations in that area. There were few contacts madewith platoon or larger sized units; however, the ist Bn, 12th Inf and Ist Bn,22d Inf were continually involved with contacts involving 2 - 3 individualscategorized as local VC and NVA. These snall. units were primarily concerned withtransporting food from the coastal plain to the area west of the An Lao Valle%.On several occasions, the 2d Bde was able to establish contact with company orreinforced company sized elements.

(b) Artillery support remained responsive to the ground commanders who weruencouraged to use recon-by-fire techniques. The employment of one howitzerwith each round being adjusted by the Forward Observer assisted in orienting themaneuver element in mountainous terrain as well as insuring rapid applicationof large volutmes of fire when required.

(c) Because of the mountainous terrain on both sides of the An Lao Valley,direct communications to firing batteries could be established only through theuse of a retransmission station. The secure voice capability was maintained byreleying between elements.

Another aircraft and crechief were based at An Khe in supoort

of the 6-29th Artillery. This section achieved high aircraft availability ratEsduring the first two months of this period due to the excellent maintenancefacilities at organisational level and the suoort from the 704th MaintennnceBattalion.

2 During January, two aircraft were deaclined awaiting parts (EU') fcrraln rotor heads. These aircraft rereived blae strikes at two locationsbecamse of flying debris. This caused an increase of blade tine on theremnining aircraft.

Letters have been dispatched from this vffice to cormza~ders of theunits in the field reqesting aaslstance in making their pads safer. lessonplns concerning Aviation Safety were sent to all units in Divisiun Artillerye*pl.ining the importance and need for a safe landing pad - one free df flYingdebris that cculd cause damage to a helicupter.

(1) Sunpressive Fires for Evacuat'on of a Firebase or Linding Zone.

(a) OMSEVATDN: Large slcv flying aircraft frequently receive smallarms fire when airlifting heavy ecuipment out of a landing zone.

(.b) EVMAT1 DNs When landing zones are being evacuated, the enery willfrequently use the noise and activity on the firebase to cover his movementto positions from which he can direct small arms fire at approaching anddeparting aircraft. On occasion, aircraft lifting heavy luads have receivedhits upon rdeartbra with the result that the load was jettisoned in order totake evasive action. This can often by p recluled by firing suppressive artilleryfires along thr rcates of approach and egreas used by the aircraft just -riorto entry and departure from the LZ.

(c) REZO0 IENTDNs That suppressive artillery fires be planned and

(2) Timeliness of fires on APD Siings

(a) OBERVATIONt There has existed an unsatisfactory time lag between

tim Of APD sensing and time of engagement with-artillery fire.

(b) EVAMAT0N: Die to a lack of direct cominications between AD air-craft Pnd supporting artillery units, timely fire is not being delivered onAPD sensing. Reports currently go to the 3de S-2, controlling the APD mission,and then are passed to the firing unit. This procedure results in excessivedelays in engaging the targets with artillery fire.
