(3) BT 425158 – In this vicinity a fence with a strip of punji stakes was observed running east west for about 300 meters. The fence was made of branches from thorn bushes and the strip of stakes was at the widest 1 meter in width. It was a very flimsy obstacle.

It was 2 feet wide and averaged one meter in depth. The northern leg of the U had fighting holes. A series of man traps ran along the outer edge of the fighting positions. The holes were 1x1x1 meter with two-foot punji stakes inside the hole camouflaged with a bamboo lacing covered by sand. The mantraps were slightly depressed by the heavy rain and therefore visible if one was looking for mantraps. The position had 800 meters of grazing fire to the north and 1500 meters to the east. Signs indicated two men had occupied the position the morning of the 18th.
(5) BT 428147 – A trench line running northwest southeast on hill, 200 meters long and 1 meter deep. It offered excellent observation and fields of fire to the north and northeast. There were several one man fighting holes forward of the trench.
