1. (C) GENERAL ENEMY SITUATION:
The intensity of enemy initiated activity decreased over the last reporting period even though enemy initiated incidents totaled 466, an increase of 22 from last week. The total number of incoming rounds decreased to 611 from 1622 for the week ending 11 April. There was a decrease in the number of enemy KIA's: 965 compared to 974 for the previous week. The number of PW's was 91, 38 more than the previous period. There were 91 incidents of mines and booby traps reported versus 88 for the last reporting period.

B. Thua Thien (P):
Activity within the province during the reporting period remained at a relatively high level. NVA forces in the western mountain region continued to make their presence felt by conducting attacks by mortar, RPG, and small arms fire. Action seemed to be concentrated around FSB Ripcord and FSB Veghel. In a recent incident 1/2 km east of FSB Ripcord (YD 343192), C/2/506 rceived mortar rounds, RPG rounds, and small arms fire from an estimated platoon-size force. Elements returned small arms fire and organic weapons fire. The results of the contact were 2 US KIA and 8 US WIA. It is believed that elements of the 6th regiment are the principle aggressors in this area. In another contact 1 km northeast of FSB Katy (YD 445158) on 7 April, the CP, D/1/506 Inf, received RPG rockets from an unknown size enemy force. The element returned organic weapons fire. Results were 1 US KIA, 26 WIA. This incident may have involved the K12 Sapper BN/6 Regiment.

In activity in eastern Thua Thien Province it was learned through PW interrogation that the Chi Thua I and Chi Thua II Sapper Battalions were responsible for attacks on FSB Arsenal and FSB Anzio respectively. On 6 April 70 at FSB Arsenal, C/1/502 Inf received an unknown number of RPG rockets. Shortly thereafter, 4 sappers attempted to penetrate the perimeter wire. Artillery, ARA, and flare ships were employed. Ten minutes later, 2/C/1 of the 502d Inf, in their ambush positions, observed 15 enemy 150 meters southeast of their position. ARA was employed. Results of the contact were 4 US WIA, 6 NVA KIA, 2 NVA PW's, 12 RPG rockets, 78x1/4 lb satchel charges, 5 bangalore torpedoes and a 30 lb TNT block. Finally on 7 Apr 70 at FSB Anzio, (YD 933073), the regt CP, HHC, and Rcn Co/4/54 ARVN received approx 100 mixed RPG rockets and mortar rounds followed by a sapper attack from an estimated 80 enemy.

4. (C) COUNTERINTELLIGENCE:
A. General:
Enemy initiated activity continued at a high level during the reporting period. The majority of the incidents occurred at the early portion of the week as the enemy "high point" tapered off. Activity was not centered in any one province, but was spread across the entire XXIV Corps AO.
There were 32 reported politically oriented terrorist incidents. These incidents resulted in 17 people kidnapped, 9 civilians killed, 60 civilians wounded and 206 homes/buildings destroyed or damaged. While these figures are high, they represent a decrease from the previous reporting period. Quang Nam (P) and Quang Ngai (P) were the locations of the majority of these incidents, with rural hamlets and rural GVN Pacification Program centers being the targets for most of the late reported incidents.
A look at the past week's sabotage activity indicate that the interdiction of National Highway 1 was one of the enemy's objectives during their recent "high point". Six reported incidents occurred on Highway 1 and one incident involved the Hue-Da Nang Railroad Line.
There were three reported incidents of propaganda, all in Thua Thien (P). This figure is expected to rise in the coming weeks as it is felt that the VC/NVA will attempt to capitalize on the propaganda value of their increased activity. There were no reported incidents of espionage, during the reporting period. This was possibly due to the enemy's interest in more ostentatious forms of activity.
Miscellaneous significant reports include:
1. A directive, classified Top Secret, possibly issued by the Current Affairs Committee, Dien Ban (D), Quang Da Special Zone, Region 5, pertains to VC guerilla activities.
2. A directive, possibly issued by the Current Affairs Committee, Dien Ban (D), Quang Da Special Zone, Region 5, pertains to the Political Struggle and Military Proselyting phase of action.
3. A captured enemy document which pertains to enemy fifty columnists in Quang Dien (D), Thua Thien (P).
4. A reported incident of VCI recruiting attempt in Phong Dien (D), Quang Ngai (P).
B. Espionage: There were no reported incidents of enemy espionage activity during the week.
C. Sabotage:
National Highway 1 was the scene of six reported incidents this week and one incident occurred on the Hue-Da Nang railroad line. Also, three late reports from the previous reporting period involve interdiction of Highway 1.
1. Thua Thien (P): On 6 April, 1970, at 0930 hrs, an individual, while sweeping railroad tracks vic ZD 064017, detonated an unknown type mine, resulting in four RF KIA and 6 feet of rail damaged. (Thua Thien Sector INTSUM 96-70)

D. Political:
Terrorism remained at a high level during the reporting period, with 32 reported incidents accounting for 17 people kidnapped, 9 civilians killed, 60 civilians wounded and 206 homes/buildings destroyed or damaged. There were 56 late reports of terrorist incidents, boosting the totals for the previous reporting period to 74 reported incidents involving 50 people kidnapped, 67 civilians killed, 169 civilians wounded and 165 homes/buildings destroyed. These statistics, over a two week period of increased enemy activity, indicate the increasing emphasis the enemy places in the political objective of destroying the people's faith in the GVN as a viable form of security.

5. (C) ENEMY CAPABILITIES AND VULNERABILITIES:
A. Courses of Action:
Based upon a continuing evaluation of the enemy forces within and contiguous to XXIV Corps AO, enemy capabilities and courses of action are:
1. Continue prosecute the war at present levels, maintaining pressure on ARVN/FWAF by conducting attacks by fire, limited ground attacks, and light to moderate sapper attacks.
2. Increase these levels of military activity, launching periodic offensives of limited scope and duration.
3. Launch multi-regimental to division size attacks across the DMZ and from western base areas toward the lowlands supported by all available artillery with the intent of inflictin attacks across the DMZ and from western base areas toward the lowlands supported by all available artillery with the intent of inflicting maximum casualties upon friendly forces and to take and hold population centers. The threat by geographical area follows:
a) Attack installations in Northern Quang Tri (P) with up to six infantry regiments supported by two sapper battalions and three artillery regiments.
b) Attack Quang Tri City from the south with up to five infantry battalions supported by two sapper battalions and one rocket/artillery battalion.
c) Attack the Hue/Phu Bai area with elements of five infantry regiments supported by two mortar/rocket battalions.
d) Attack installations in the DaNang TAOR (area surrounded by BT 1858, AT 9168, AT 8983, AT 9384, AT8443) with the equivalent of up to five infantry regiments supported by five sapper battalions and two rocket battalions.
e) Attack the Tam Ky/Chu Lai Combat Base with two infantry regiments supported by four sapper battalions and two artillery battalions.
f) Attack population centers in Quang Ngai (P) with the equivalent of two infantry regiments supported by two sapper battalions and one artillery battalion.
4. Revert to guerilla warfare with emphasis on the more traditional insurgent tactics of wide spread hit-and-run raids, sabotage, terrorism, attacks-by-fire, and intensified political-economic warfare.
5. Reinforce forces presently in XXIV Corps AO with two to three divisions from North Vietnam either across the DMZ or via the Laotian Panhandle, to effect either course of action (1), (2), or (3) above.
6. Defend positions just north of the DMZ with up to six infatnry regiments supported by two sapper battalions and three artillery regiments; defend elsewhere in XXIV Corps AO south of Route 9 with forces locally available.
7. Conduct terrorist, political, propaganda and proselying activities in conjunction with any of his courses of action.
B. Analysis and Discussion:
In the upcoming week there would be a little change in the pattern or intensity of enemy activity as experienced last week. He is expected to continue consolidating his positions and preparing his forces for phase II activities scheduled for late April or early May. Reconnaissance of selected targets will continue as will resupply of local forces. Offensive activity should be charactized primarily by attacks-by-fire and small ground probes. Activity in Northern Quang Tri migh be an exception, as elements of three regiments are congregated in the Mai Loc area. The 27th NVA Regiment will continue it's offensive operations against friendly forces and installations in the area. Elements of the 246th NVA Regiment have not yet been committed to battle but with disposition of forces immediately west of the Camp Carroll/Mai Loc area employment could be made at any time. Elements of hte 66th NVA Regiment continue to prove a threat from the south.
C. Probable Courses of Action:
During the coming week the enemy will continue his battle in the Central DMZ area while attempting to infiltrate additional forces into the Ba Long Valley, Mai Loc area. In MRTTH the enemy will continue to improve his positions, cache sites, and resupply routes in his newly created base areas to the west of the old base areas 101 and 114, and will continue to react quickly and violently to all Allied intrusions in those areas. In the southen three provinces of the Corps AO the enemy will continue his current level of activity. Offensive activity will remain primarily attacks-by-fire with some limited ground and sapper attacks. His major concern will be primarily continued preparation for upcoming Phase II of the offensive.
D. Vulnerabilities:
1. Massed enemy forces remain vulnerable to detection and subsequent destruction by tactical air, ARA, B-52 strikes, artillery bombardment, and combat assault.
2. Enemy forces infiltrating into the Corps AO remain vulnerable to interdiction, artillery and aerial bombardment, detection and isolation by reconnaissance elements, and defeat in detail by Allied combat operations.
3. Enemy morale is vulnerable to psychological exploitation by propaganda concentrating on NVA/VC defeats in combat; failure of the NVA to support the needs and aspirations of the people, contrasted with GVN ability to support these needs and aspirations; fear of death, battle hardships, disease, poor medical facilities, and lack of food supplies; and failure of VC sympathizers to establish a popular political power base in XXIV Corps AO.
