When Drummer describes the protections he designed for Pajaro's camp, he mentions "punji sticks". These are simple wooden stakes which are often used as booby traps. They can be deployed in many ways, but one of the most effective is to dig a pit and position the sticks so that they are pointing downwards inside of it. That way, when the person tries to get out of the pit, they cannot do so without either severe damage from impaling themselves on the sticks, or are forced to spend a great deal of time and effort to remove the sticks from the pit first. Punji sticks were also often poisoned with fecal matter to insure a dangerous infection was incurred by any wound caused by them. These weapons were often used in Vietnam, among other places.
