2. Open-wire Telecommunications Traces, Panhandle Area, Laos
Four new open-wire telecommunications traces have been identified in
the Laos Panhandle, with one extending into South Vietnam. For convenience
the traces are labeled A, B, C, and D in the descriptions below and on the
map on page 3.
The first indication of a telecommunications trace was on photography of
when line B was identified in the vicinity of 16-32N
Lines A, C, and D were first observed on photography of
25X1 D
Original interpretation was made on 111111111111 photography, but
quality and scale precluded identification of any poles or wires. Subsequent
low level coverage has revealed poles, crossarms, insulators, and wires
being installed on the northern section of line A.
106-17E.
A. This open-wire telecommunications trace is observed from its
northern terminus at 16-49N 106-19E (IMMIR south to 16-34N 106-23E 25X1 D
1111111111. From this point a probable trace is observed under construction
in the vicinity of 16-31N 106-25E (MM. and 16-31N 106-23E (11, 25X1 D
approximately 2 nm north of line B. The northern end of this line will
probably aonnect with the existing DMZ line which ends near the Laos/South
Vietnam border at 16-53N 106-31E Poles are intermittently
observed on the northern segment of this line between 16-41N 106-23E
11111111111and 16-49N 106-19E ( . The poles have a single crossarm
with two insulators, both located on one side of the arm. A short section
of dual wire is also observed at but this appears to be only an 25X1 D
isolated section of advanced construction. (See Figures 5 and 6).
B. This 70 nm trace generally parallels Routes 91)-i- and 92, maintaining
a 1-3 nm distance from the road. It extends from 16-41N 106-00E 411.11111, 25X1 D
7 nm west of Sepone, to 15-54N 106-41E MMIll 6 nm northwest of Ban Bac.
C. An open-wire telecommunications trace is intermittently observed
extending north from line B at 16-2315 106-32E IIIIIIIIIII The trace turns 25X1 D
east, paralleMng the Tom Rou (River), and continues through the village of
25X1 D Pe Riang at 16-2615 106-37E (MINIMMOL terminating approximately 0.3 nm from
the Laos/South Vietnam border at 16-2715 106-40E (Figure 7). 25X1 D
D. The fourth trace, possibly an extension of Line C, generally
parallels Route 922 in Laos and continues into South Vietnam. It is inter-
mittently observed from the limit of interpretable photography of approxi-
mately 16-2015 16-2oN 106-)-i-7E IMMMI, across Route 922 at 16-1515 106-56E

3. New Road South of Route 9, Laos/South Vietnam Border Area, Laos
Newly observed road construction extends east from Route 92 at
16-29N 106-29E 11111to the Laos/South Vietnam border at 16-29N
106-39E C Vehicle tracks are observed east to 16-29N 106-36E
From this point initial clearing and grading are observed for
3 nm to the border on the west bank of the Se Pone River (Figure 9). Across
the river foot trails lead east and north from the Lang Tenouo area.
Two probable truck parks and several weapons positions are observed
along this road. Probable truck parks are located north of the road at
16-29N 106-32E land l6-30N 106? E . Five heavr 25X1D
artillery sites are located at 25X1D
and These are served by roads showing a minimum of initial
clearing and vehicle tracks (Figure 10). All of the artillery sites have
been struck, and one position at bao an overturned 122/152 mm 25X1D
Howitzer (Figures 11 and 12). Five HMGAA sites have a total of 21 positions
(17 occupied) in clearings in the area. Ban Houei Sane, a Royal Laotian
Army strongpoint, village, and airstrip, was reportedly shelled from
weapons in this area prior to being overrun (Figure 8).

Occupied AAA sites were observed in the Ban Bong area on photography
25X1D of Three sites, each with four light, 37 mm AAA pieces
were identified along Route 9 at 16-38N 106-24E
25X1D (Figure 15). All positions are revetted and camouflaged.
Heavy trail activity, several unoccupied AAA sites, and numerous AA/AW
positions, foxholes, and trenches were also observed throughout the area.
Route 9 east of Ban Dong is now serviceable with evidence of medium-
to-heavy usage to the Ban Houei Sane area at 16-36N 106-32E
This is the first time this segment of Route 9 has been observed in use
