In Part 1 of this article we discussed the construction and installation of stationary booby traps, traps that require no motion to cause damage. In Part II we are going into some ideas on 'Moving Booby Traps', or traps that cause damage due to their movement. Note that placement of these traps as in Part I requires a location that is a well traveled foot path or an avenue of approach to your hideout or survival shelter. In both instances, camouflage is the key factor to installing an effective trap. I would like to point out that the traps illustrated in this article were all used very effectively against out Armed Forces in Viet Nam, and can be very deadly. They are definitely not toys to play with.
trip wire is pulled, it removes one of the retaining sticks and allows the Whip to spring towards the trail striking anyone in it's path. Notice in Fig.2, how simple the trigger mechanism is to construct. The various traps described here all use a similar trip mechanism which is readily*constructed from materials at hand. The principle of keeping the trip mechanism as simple as possible and the use of one type of mechanism for several trap designs reduces the amount of equipment that a person may have to carry in the construction and placement of these traps.
The first type of trap is called the 'Whip.' In this device, a young sapling, about 1-1/2 to 2 inches in diameter, Is tied crossways to a sturdy tree along the side of a well traveled path or approach and is positioned so that it's end will be about'chest high in the sprung position.. Fig.1 A Spike Board similar to the one that was used in the Spike Pit Trap (PMA vol.1 #3)is tied to the sapling in such a manner that it will strike whomever trips the wire in either the chest or back; depending on their direction of travel. The sapling is then bent back away from the trail and secured with the trip-wire mechanism. When the The next device Is called the 'Angled Arrow' trap. It is constructed and placed in a pit in the ground which has a sloping bottom. Fig.3 The arrow platform is constructed from a piece of board a-bout I in. thick, 3 ft. long, and about 12 in. wide. A guide channel, such as a piece of tubing, is fastened to the board to direct the arrow in the desired direction. Two spikes are driven into the board on a line across one end of the tube and are used to secure the rubber bands. The rubber bands can be made by cutting up an old inner tube or you can use surgical tubing. The trigger mechanism is constructed out of steel rod or a large nail, and uses the same principle as that of the crossbow. Remember that the rubber bands exert a constant strain on the trigger mechanism and therefore /must be the strongest part of the trap Fig.** Note that the trigger trigger mechanism wire is set into a small hole in the board as well as being held in place by the pivot rod. Any tension on the trip wire rotates the trigger wire on the pivot axis, releases the rubber bands and causes the arrow to fly out of the tube.
The third trap is called the 'Pivot Spike Board'. This one Is used in conjunction with a foot pit. When a person steps on the treadle, the board with spikes, Fig.5, pivots about an axle and strikes the victim in the leg. A variation of this trap is called the 'Sideways* trap and is shown \n Fig.fc. This one Is usually placed at the top of a pit about U feet deep and Is camouflaged. As a person steps on the trap, he dislodges the prop stick, which releases the rubber bands, causing the sides of the trap to close. As the victim is falling, the spikes rake his body, arms, and legs, causing much damage.

The final group of moving traps are suspended above the trail or path. The first is a 'Log Mace1, a small diameter log 8 to 10 feet long with spikes driven into it. It is suspended from an overhead tree so that the spikes are about chest hIgl\ and then pulled back up into a second tree and fastened to the trip mechanism. When the trip wire Is sprung, it swings down along the path hitting anyone in the way. Fig.7 Two variations of the Log Mace are the 'Spike Ball1, which is a large cement ball with spikes in it, and the 'Suspended Spike Board1. Figs. 8 & 3. With the Suspended Spike Board, the device falls straight down on the person springing the trip wire. It has also been known as the 'Tiger Trap'. This one can really be deadly. Again, I remind you that these devices can cause severe injuries and care should ¿>e taken when building and setting them up.
