Another Vietcong trap was the Punji trap. Two wooden platforms were placed and covered with leaves to camouflage it. There were spikes on the inside of the wood. When a soldier came along and walked on the wood, it caved in and the spikes would go through the soldier’s foot. These traps were the most common because they were the cheapest and very effective. They also were often contaminated (often with feaces) so that the soldier would also become infected.
