I. THE MILITARY SITUATION IN SOUTH VIETNAM
1. A US Marine battalion command post 15 miles
northwest of Quang Tri city was attacked on 18 April,
possibly reflecting Communist concern over the defense
strip which is being constructed immediately south of
the DMZ in northernmost Quang Tri Province. Two
Americans were killed and 13 wounded in the brief at-
tack.
2. Other enemy efforts against US and South Viet-
namese troops working on the barrier have included
scattered firefights and the laying of mines in the
construction area.. Several construction vehicles have
been damaged or destroyed by the mines.
3. Total casualties sustained thus far by the US
Marines who are pushing westward from Gio Linh, were
reported as four killed and 62 wounded. The South Viet-
namese are building their section between Gio Linh and
the sea.
Further Communist Planning :--.evealed by Defector)
4. Further interrogation
as revealed a i-
tiona information on o planning to counter the
effectiveness of the Revolutionary Development program.
that emphasis will be placed on devel-
oping the guerrilla warfare movement and on converting
party members and sympathizers to active guerrillas.
Sabotage of roads in the government-controlled areas
will also be increased. The Viet Cong hope to prevent
completion of pacification objectives during the dry
season and then work against the towns and cities dur-
ing the rainy season.
5. a four-man North
Korean advisory group arrived in South Vietnam in early
1967 to obtain information regarding the deployments
and tactics of the South Korean troops and to study
infiltration routes into the country. The defector
claims that North Korea has offered to provide a di-
vision of troops, but that so far, only medical supplies
have been received. There is no other in._ormation to
confirm the prisoner's statement on the offer of troops.
North Korea, as have other bloc countries, has promised
in propaganda statements to send "volunteers" if re-
quested and when needed.

Enemy Activity Since Tet
6. Intensive Communist activity and a more
aggressive attitude have characterized enemy opera-
tions since the end of the four-day lunar new year
holiday period, Tet, from 8-12 February.
7. The increase in activity was revealed in a
study of monthly figures before and after the Tet
period. The number of Communist-initiated attacks
for the two-month period prior to Tet averaged 121
compared with 168 for the two months following the
cease-fire period. In contrast, the over-all 1966
monthly average of attacks was 78.
8. Since early February, the enemy has used,
for the first time in South Vietnam, the 100-mm.
field gun, the 105-mm. howitzer (fired from across
the DMZ), and the 140-mm. rocket launcher. An es-
timate of the total number of rounds of artillery,
mortar, recoilless rifle and rocket ammunition ex-
pended in enemy attacks also show a large increase
since the first of the year. In January, a total of
2,183 rounds were =i:_:'ed in comparison with 5,075
fired in March.
9. As more allied troops deploy to positions
throughout the country the number and frequency of
these artillery-type attacks against allied military
targets can be expected to increase further. It
has also been noted that the enemy has intensified
his efforts to offset the Revolutionary Development
program, especially in the northern provinces of
I Corps.

1. Preliminary field reports indicate that, the
largest air battle c= the war may have occurred on
19 April in the wake of a major US air strike on the
Xuan Mai army barracks 25 miles southwest of Hanoi.
At least 17 separate air engagements have been reported
involving approximately 28 MIGs and 20 or more US air-
craft. Initial reports of the results of these en-
counters indicate one USAF A-lE and one MIG-17 downed
and several additional MIGs probably lost.
2. The Xuan Mai barracks is believed to be a
special training center for large infiltration groups
being deployed to support Viet Cong and Pathet Lao
insurgency operations. Preliminary reports suggest
that the initial strike force of 16 F-`05s did major
damage to this target and escaped without encountering
any MIGs or sustaining any losses. A second wave of
F-105s which struck the barracks 30 minutes later,
however, ran into major ground and missile fire and
became heavily engaged with large numbers of MI.-17
fighters.
3. The loss of one F-105 to ground fire caused
his wingman and two A-lEs to stay in the target area
to provide air cover for the downed crew. .Separate
groups of MIG-17s attacked these planes and in the
ensuing engagements one A-lE was brought down by a
group of four MIG-17s and the F-105 shot down at
least one MIG-17. The details of 15 other encounters
with Communist interceptors have not yet been received
but early reports indicate that five more MIQs may
have been shot down by US pilots.
