(FOR KEY SEE REVERSE)
1. In enemy cleanup operations considerable attention is being devoted to searching
for our hiding places. In some cases the enemy remains in a village for a long
time searching for them.
2. The enemy makes reconnaissance of underwater noises and searches for air vents
which will betray the presence of underwater hiding places. They seldom descend
into the hiding places but'throw grenades through the air vents. War prisoners
are often sent into the hiding places to search for us, but experience has
taught that if we threaten and spare the life of the prisoners, they do'Pot
betray our presence.
3. A n improperly executed descent into the hiding places leaves evidence of Pur
presence. The last person to descend must carefully destroy his traces by
arranging the bushes and branches properly behind him. This is required
particularly for the underwater hiding places where there are many water lilies
in the ponds.
4. Hasty departures should be avoided. Conventional signs must be arranged with
outside agents, and departure should be made only upon recognition of these
signs. Preferably, departure should be made only by prearrangement.
5. Consideration must be given to sanitation facilities if underwater hiding places
are to be occupied three to seven days. Supplementary air vents can be drilled
through the inside and a pickaxe is needed for excavation.

6. Only those locations which afford natural cover and are-least suspect should be
selected.. The walls should be sturdy and. thick in order to avoid detection by
thumping on the ground with pickaxes and iron rods. When conditions are
favorable it is advantageous to have thin walls to permit quick exits.
7. A trdh of at least forty centimeters should be constructed at the entrance
in the event the hiding place is discovered and the enemy throw grenades through
the entrance .
8. Hiding places should be constructed in a zig-zag pattern to avoid repercussions
from grenades thrown through the entrance.
9. The entrance and the air vents must be well camouflaged. The air rents should
be numerous and small in size. They should be tested to ensure proper,
functioning.
10. Hiding places should be constructed both inside and ouside of the villages.
If there are hiding places outside the villages only, the combat morale of
the guerrillas will be affected in their defense of the villages. Within the
walls of the village, hiding places should be constructed away from the
administrative centers.
11. Locations for hiding places outtideAthe villages must be carefully selected to
avoid areas where movement of enemy tanks will cauze their collapse. Also
to be avoided are locations where exposed approaches make detection of
exit and entrance traces easy. Hiding places must be checked regularly and
kept in usable condition at all times.
12. A preliminary assignment of responsibilities must be made to each person in
the hiding places. Outside agents must be initially selected from among the
mothers or wives of the guerrillas who are in the hiding places.
13. Where construction of an underwater hiding place leaves a detectable disturbed
area, buffalo dung mixed with the water will calm the water within several house.,.
