 Ted not only heard the voices, but was close enough to even smell the odor of marijuana that they smoked as they walked down the trail. Another noise ahead of them in the bushes aroused the Marines' senses. Ted pushed the selector switch on his M16 rifle with his right thumb from safety to full automatic, ready for the assault. Then a squeal came from the bushes. A wild boar suddenly ran across the trail in front of the North Vietnamese regulars, and they fired their AK-47s at the pig.
