PREFACE
This report is a summary of selected information
on transportation and infiltration activity in southeast
Asia as reported by NPIC during the period indicated
on the cover. Those lines of communication and associ-
ated facilities which support communist insurgency in
Laos and South Vietnam are emphasized.
Items are numbered and arranged according to location
from north to south. . Annotated maps of varying scales
have been included to assist the reader in locating the
items. Each large-scale map depicts all motorable roads
photographically confirmed by NPIC unless otherwise in-
dicated.
Missions, mission dates, frames, and NPIC cable
and briefing board references are listed after each item,
as appropriate.

1. Vehicle Support Facilities, Route 911, Laos
Seven active probable truck parks and suspect rest and refuel areas
have been recently identified along Laos Route 911 between 17-ION 105-50E
and 16-54N 106-OOE. Like other vehicle support facilities in the Laotian
Panhandle, they are characterized by hastily cleared roads under dense
tree canopies with an absence of identifiable buildings. A brief
description of each with UTM coordinates follows:
1. Suspect Rest and Refuel Area: parallel service roads extend west
from Route 911 at WD891936 and WD891992 to terminate at WD886983
and WD881981, respectively.
2. Probable Truck Park: a short loop road is located west of Route
911 between WD914968 and WD91.5967; a single parking lane extends
east from Route 911 at WD915967 to WD916974.
3. Probable Truck Park: a single parking lane extends northwest
from Route 911 at WD931945 for at least 100 yarc.s (Figure 1);
three unoccupied AW/AA positions are located east of the route
at WD923940.
4. Probable Truck Park: a single parking lane extends north from
Route 911 at WD954916 to WD956923, then southeast to WD965908.
5. Suspect Rest and Refuel Area: a service road extends southwest
from Route 911 at WD953922 and terminates in a turning loop at
WD944912 (Figure 3).
6. Probable Truck Park: a single parking lane extends south from
Route 911 at WD996765 to at least WD995760 (Figure 2).
7. Probable Truck Park: a loop road is located east of Route 911
between XD079700 and XD079701; a short service road with several
parking slots continues east from the loop road through the
village of Ban Sop Khum, to XD081701.

2. Motorable Infiltration Route Under Construction, Laotian Panhandle
A motorable infiltration route which will connect the North Vietnam
road and trail network in the demilitarized zone with Thus, Thien Province,
South Vietnam, is probably in late stages of development. Construction
has begun on an extension of Laos Route 92 north from Route 9, toward the
Se Bang Hieng River Valley which crosses the Laos/Vietnam Border at the
Vietnam Demarcation Line. Laos Route 922 construction, reported in Summary
37, now crosses the South Vietnam Border and extends to A Luoi, an
abandoned air strip and strongpoint in Thua Thien Province. If completed,
these two Laotian roads will provide a motorable infiltration route
approximately 70 nm long, which will completely circumvent the allied troop
concentrations in the vicinity of the Demilitarized Zone.
Laos Route 92 is being extended north from Route 9 at 16-38N 106-25E,
UTM coordinates XD519397 (Figure 4). Vehicle tracks are observed on a
completed road segment to UZM XD523411; construction is in mid-stage to
UTM XC522422, where a culvert/bridge has been completed (Figure 5); and
trail widening and initial clearing extend north to the limit of photographic
coverage at XD528431.
Although a complex network of trails at least one of which was
extensively improved -- has connected the Laos Route 9 area with the
Vietnam Demilitarized Zone since his is the first indication of an 25X1D
intention to construct a motorable link between these two points. North
Vietnam Route 102 was extended into the Demilitarized Zone in 25X1D
with probable road construction continuing west toward Laos to 16-54N
l06-44E, UTM XD853688 (summary 14). Construction was subsequently aban-
doned, probably due to a combination of repeated air strikes and severe
weather. The current status of this construction is unknown.
Construction continues on the eastward extension of Laos Route 922
into South Vietnam. Vehicle tracks on the completed segment now extend
to 16-17N 107-OOE, UTM 1151023 (Figure 6). Construction is in mid-stage
to UTM YD232045, generally following the border alignment; intermittent
road clearing and earth moving activity continue north into South Vietnam
to UTM YD232082, then east to UTM YD278092; and trail widening and road
clearing continue southeast to A Luoi at UTM YD385004 (Figures 7-11).
River crossings have been improved at UTMs YD301090 and YD367025 (Figure 10).

3. POL Storage Area, Route 922, Laos
A POL storage area is located immediately east of Route 922 at 16-16N
lo6-57E (UTM Yco88995). Thirty-three POL drums, probably 55-gallon
capacity, are partially buried in three trench-type excavations and an
additional 34 drums are scattered in the vicinity (Figure 12). Soil in
the heavily cratered area probably facilitates the burying process. A
25X1D probable camouflaged truck was observed parked in the tree line near the
storage site on (See map, page 15.)

4. Constructed Ford, Ban Bac Area, Laos
A constructed ford crosses the Se Kong (river) immed_'_ately east of Ban
Bac in the vicinity of 15-50N 106-47E (between UTM coordinates XC924523 and
XC922521). Although its operational status cannot be determined, there is
some evidence of usage. Route 92 has been extended along the river bank to
provide a northern approach to the ford and vehicle tracks are evident on
the southern approach road from Route 923. The construction of the ford
coincides with the indications of increasing vehicular activity on Route 96.

5. POL-Type Drums, Se Kong (River), Laos
Approximately 30 POL-type drums were observed along a 3.2 nm segment
of the Se Kong (river) between 15-35ji l06-46E and 15-38N 106-47E on photo-
graphy of (Figures14 and 15). This segment of the river lies in 25X1D
the southern half of the water-borne supply route first reported ii
_to have been reactivated between the Ban Bac area and the western
terminus of Route 964 (Summary No. 35).
The drums, probably 55-gallon capacity, were observed approximately
half submerged when floating; however, most of them were trapped on rock
outcrops or along the river bank. A total of 123 similar drums were
subsequently observed grouped along the entire water-borne route on
photography of
The constructed and improved channels (Figure 16) -- identified in
prior to the extension of the communist road network south of
Ban Bac -- have been re-established and are being maintained.

6. Probable Insurgent Activity, Rach Cai Bac (Stream), Cambodia/South
Vietnam Border Area
There are indications of probable insurgent activity along the Rach
Cai Bac (stream) in the vicinity of 11-27N 105-53E, approximately 15 nm north-
west of Tay Ninh City. The stream, this segment of which forms the border
between Cambodia and South Vietnam, is known in Cambodia as the Stoeng
Kampong Kdei (stream).
A probable transshipment point containing two partially concealed
storage-type buildings is located on the stream bank at tTTM WT991645
with a well-used trail extending east from the river to loin the South
Vietnam road network. Extensive row crop agriculture is located along
25X1D the stream bank at UTM WT960660. A motorized river craft was observed
in the vicinity of each area on (at UTM coordinates WT961677
and WT988639).
A probable insurgent support area in the vicinity of 11-33N 105-52E
was reported in Summary No. 38.

7. Probable Insurgent Bivouac Areas, Cambodia/South Vietnam Border Area
Three probable insurgent bivouac areas have been newly located in
Cambodia approximately 2 nm west of the South Vietnam border, in the
vicinity of 11-02N 106-09E (at UTM coordinates XT272197, )T260199 and
XT262202). Numerous foxholes and at least four AW/AA positions have
been identified along the periphery of the three isolated wooded areas
(Figures 17 and 18). There are extensive trail networks within each area
and evidence of heavy vehicular activity in the adjacent fields.
Possibly associated row crop agriculture is located at UTM XT255206.
Additional foxholes have been identified in the vicinity of the 0 Tapou
(creek), south of Cambodia Route 1, where at least 100 water buffalo
were observed between UTM coordinates XT220217 and XT258198. Herds of
this size are incongruous in this area of sparse indigenous habitations,
indicating the activity is probably insurgent associated.
