Punji Traps are a unique trait of war that the Viet Cong specialized in. These are basically just booby traps, but were extremely deadly. Some Punji Traps consisted of a trap door in the ground, that when stepped on, would fall through and the soldier would fall down onto anywhere from a few to dozens of sharpened sticks of hardwood or bamboo and impale themselves; many soldiers died like this. Other smaller Punji traps consist of the same idea but on a smaller scale that could only fit your foot per say. You would step in a small hole where the trap door would give way and your foot would fall onto many sharpened sticks and sometimes pointed metal rods and impale your foot. This in turn would make you incapable of walking on your own and would drag down yourself, your fellow soldiers, and the mission.
