(3) Significant Mnemy Tactics and Teomiquess During the months ofFebruary and March, the amount of enemy attacks and their intensity waslight. Standoff attacks and mall unit ground actions wre characteristicof enemy operations. There vas a slight rise in the intensity of the at-tacks in the Southern provinces - reaching a high point about 15 March.During the same period, PH U MW Province experienced a marked increase inabductions and ilpressment of civilians, Eaemy activity throughout theU1 Corps area was dramatically increased an 31 March. Up to battalionsin units engaged friendly installations supported by greater thav nnr-ua l smounts of varied ordnance. Using intense attacks by fire and employ-ing ground elementsp the enemy attempted to overrun the Allied camps inthe DAK SING - DA K ?K area. Th e enemy also increased ground to airfire. By aid April, the enemy action in the highlands had diminished tosporadic standoff attacks of varying intensity. The remainder of theCorps area also experienced a decline in enemy initiated action as Aprilended. Th e enemy is continuing to fragment unite into smaller elementsso as to conserve his forces by presenting maller targets. The greaternumber of unite thus available can provide tactical coverage of a wider"geographicalarea.

(b) hemy Vulnerabilities:I Enemy supply areas are generally insecure, rendering supply cachesvulnerable to friendly search and destroy operations.& The enemy has limited logistical support and cannot conduct extendedoffensive operations, unless he is near sanctuary areas.3 He is vulnerable to superior Allied fire-power when he masses nearan objective an d during withdrawal from the same.Is Continued food shortages, sickness, an d heavy losses among the enemymay lead to lov moralep a situation that can be exploited by friendly pey-chological operations.

reliance on impressed local civilians as a labor source is acourse of action that may alienate them from the populace.(e) Probable Courses of ActionsJI BM1 DIM Province - Enemy objectives are to disrupt amd destroythe GVN Pacification Program.

7 LA M DONG Province - Interdiction of the LOCs, terrorist harassmentof the villages in the pacification areas and light ground probes againstthe "1 probably will continue to be the enemy' s most probable course ofaction.I KONTM4 Province - Enemy offensive action in NW KONTUM should soongive way to standoff attacks with a probable new highpoint reached in June.However, it is estimated that no major offensive will take flaoe. Theenemy is expected to conduct attacks by fire an d harassment attacks of citiesand installations and QL 14.2PLEIKU Province - No increase in enemy activity is expected.
