--- title: The Most Terrifying Traps Used in the Vietnam War description: "From 1955 to 1973, the US and its allies waged a horrific and ultimately unsuccessful war in Vietnam. Despite losing a relatively small 58,000 troops compared to 1.1 million for their enemy, the war was emotionally devastating for the American people and the military, and some 10 percent of servicemen in Vietnam would go on to experience PTSD at some point in their lives.\n\nOne of the reasons the Vietnam War was so emotionally taxing was its guerrilla nature. In addition to fighting the conventional North Vietnamese Army, or NVA, American troops faced a force of South Vietnamese guerillas known as the Viet Cong, the infamous Charlie. They were known for their unconventional tactics, especially booby traps that they set up around the jungle where Americans patrolled. On unfamiliar terrain and fighting a resourceful, dedicated foe, these terrifying traps were as destructive psychologically as they were physically and were responsible for the many scars Vietnam veterans still wear today, on their bodies and in their minds.\n\n## Punji Sticks\n\nPunji sticks represented a simple but effective booby trap for the Viet Cong. Though rarely lethal, they arguably hampered the American war effort more than death, in part due to the psychological terror they produced in the troops.\n\nWhile there were many different designs, a booby trap of punji sticks was essentially a hole filled with bamboo spikes. When burned, the bamboo could be sharpened to a point capable of puncturing standard military boots and even tougher jungle boots.\n\nIn many cases, the hole featured spikes pointing up as well as spikes on the sides of the hole angled downward. The result was that the unfortunate soldier was essentially stuck in the hole, incapable of removing his leg without causing further damage. This halted the whole unit since they'd have to stop to dig him out rather than simply evacuate him.\n\nTo make matters worse, the Viet Cong usually poisoned the spikes. No, not with tree frog venom or something similarly Hollywood-esque—with feces, animal and human. This made infection likely, removing the soldier from combat for the foreseeable future.\n\nThe Viet Cong got creative with Punji sticks. Not only would they camouflage them under leaves and brush, they'd lay decoy traps that soldiers would avoid only to find themselves falling into other types of traps or mines off the beaten trail. The spikes were also attached to wires and tilt boards that deployed them with force to spear soldiers.\n\nA popular strategy was to cover clearings of grass with camouflaged Punji-stick traps. When a helicopter would land, a Viet Cong unit would fire on the American soldiers who would scatter through the clearing, snaring themselves on the traps in the process. In fact, the helicopter itself could fall victim to Punji sticks measuring six feet or two meters long hidden in tall elephant grass. They were strong enough to puncture the hull of the aircraft and damage it or injure passengers.\n\nPunji sticks were a terror for American soldiers, and they went to great lengths to combat them. Steel-soled boots provided some protection, but many men resorted to cutting ends off tin cans and wearing them around their lower legs like armor. Despite their efforts, the simple bamboo sticks proved a powerful weapon for the Viet Cong, accounting for a whopping two percent of all wounds suffered by American soldiers.\n\n## Bamboo Whips\n\nThe Viet Cong loved bamboo and had plenty of it, allowing them to get creative. Bamboo whips were a bit more sophisticated than Punji sticks but operated on the same basic principle: impaling unwitting soldiers.\n\nRather than burned, hardened bamboo, a bamboo whip utilized green bamboo that was springy and could be pulled back with tension and anchored on a tree or rock. A tripwire was then laid across the ground that would release the whip, which normally included a metal or bamboo spike at the end.\n\nWhen a soldier stepped on the trip wire, the bamboo whip would lash out at speeds of up to 100 miles an hour, or 160 kilometers per hour, and drive the spike into the soldier's body. Like a Punji stick, the bamboo whip could be complemented with some feces to promote infection and take the soldier off the battlefield—if he lived.\n\n## Cartridge Traps\n\nLike a Punji stick, a cartridge trap was a hidden trap placed in a hole in the ground covered with leaves and brush to camouflage it. Inside the hole, the Viet Cong placed a small-arms round inside a tube made of, you guessed it, bamboo.\n\nThe round rested on a nail stuck into a wooden board acting as a makeshift firing pin. When a soldier stepped on the trap, it pushed the round down onto the nail, igniting it and firing the bullet upward into the soldier's foot.\n\nLarge-caliber rounds were sometimes lethal, but smaller traps, nicknamed \"toe crackers\" by American troops, \"only\" caused severe injury to the foot or lower leg. Nevertheless, this was enough to slow down a unit moving through the jungle, and it created the perfect opportunity for an ambush as soldiers rushed to help their wounded comrade. Plus, the foot injuries often led to permanent disability.\n\n## Snake Pits\n\nAlthough it might sound like something out of an old cartoon, pits filled with snakes were a real waking nightmare for American troops in Vietnam, provoking psychological torment and real-world injury in commensurate amounts.\n\nCamouflaged like other traps, an unwitting soldier could fall into a pit of snakes, usually bamboo pit vipers, cobras or the Malayan krait and come face to face with their fangs. Nicknamed \"two steps\" by American troops because that's how far you'd make it after a bite, these snakes ended up being the most-used biological weapon of the Viet Cong and NVA. Aside from pits, they tied them to bamboo spikes in their tunnel networks, so the US \"tunnel rats\" tasked with clearing them of mines had to be extra careful.\n\nIn fact, Vietnamese soldiers even carried pit vipers around with them in their rucksacks. This meant that any American serviceman who went digging around in it would end up regretting the decision.\n\n## Tiger Traps\n\nPresumably originally designed to protect camps from tigers, the Viet Cong's many tiger traps quickly became one of American troops' most-feared guerilla devices. Like many of the others, sophistication and precision were thrown out the window in favor of pure brutality, which had a more severe psychological impact than a physical one.\n\nTo make a tiger trap, Vietnamese soldiers simply suspended a large board up in the trees. Then they stuck spikes all over it and added weight by attaching bricks and rocks. The board was attached to a tripwire that released the suspension when an enemy soldier triggered it, causing the board to crash down on them, impaling and crushing them both.\n\nAmerican troops also used the term \"tiger trap\" to refer to a more elaborate Punji-stick trap. In this case, a board was placed over a hole filled with Punji sticks, supported only by a fulcrum. Just a step was enough to cause the board to drop away, leaving nothing between the soldier and the sharpened points of the spikes.\n\n## Grenades, Grenades, Grenades\n\nThe MacGyver-esque ingenuity of the Viet Cong and NVA with their traps is best seen in the seemingly endless ways they turned basic grenades into terrifying surprises in the jungle. The simplest way was to lay a tripwire across a path attached to a grenade's firing pin. Trip the wire, pull the pin, detonate the grenade.\n\nA more sinister design involved pulling the grenade's firing pin ahead of time and stuffing it down in a can that would hold the safety lever down. The tripwire simply pulled the grenade out of the can, releasing the safety lever. This gave the victim of the trap less time to realize they'd triggered it before the explosion.\n\nGrenades were also a favorite anti-helicopter trap. Like with soldiers, tripwires could be placed in helicopter landing zones that would detonate grenades or larger explosives.\n\nAnother way was to take advantage of the wind produced by the helicopter's rotors. According to a Marine Corps report, the Viet Cong made a 13-year-old boy pull the firing pins from grenades and then delicately wrap the safety levers with strings attached to large pieces of paper. He then had to scatter these grenades in helicopter landing zones. When a helicopter hovered above the booby-trapped area, the wind from the rotors caught the paper like sails, pulling away the string with it and detonating the many grenades.\n\nHowever, the weirdest grenade trap was arguably the so-called \"mudball mine.\" In this case, the Viet Cong substituted mud for the can. They pulled the grenade's firing pin and encased it in dried mud or clay that held down the safety lever.\n\nThis might not sound very safe… because it's not. It didn't take much to crumble the dried mud, releasing the safety lever. They left these grenades all about the floor of the jungle, and it didn't even take a direct step to set them off. Enough nearby movement could jostle the firing pin free and injure several soldiers at once.\n\nPlus, the mud served the dual purpose of camouflage. Mudball mines were nearly impossible to pick out, even for experienced soldiers, and they left American troops fearing each step they took.\n\n## Don't Capture the Flag\n\nThe Viet Cong and NVA quickly came to learn that American troops loved war trophies. Therefore, they rigged anything in their camp they thought Americans would like before retreating.\n\nOne of the most common was the flag. The Viet Cong realized fast that Americans loved capturing their enemy's flag, so they booby-trapped their flag poles to blow when the flag was lowered. This proved so effective that they even started flying flags at abandoned bases just to kill unwitting trophy-hunters.\n\nAs a result, American troops came to recognize trophy hunting as a dangerous activity. It quickly prompted the ominous adage, \"Keepsake, lose hand.\"\n\n## Swinging Maces\n\nThe mace is both the most obvious and most terrifying of all the booby traps used in the Vietnam War. The Viet Cong made makeshift maces out of anything they could find, the round core formed of wood, metal or even straw. The core usually measured two feet or 60 centimeters in diameter and weighed over 40 pounds, or 20 kilograms. Whether tied or welded, spikes were then attached all around the ball with sharpened points.\n\nThis ball of death was suspended from a tree by a rope and then pulled back and anchored with a tripwire laid across the enemy's path. When a soldier tripped the wire, the mace swung down and impaled him to the horror of his comrades. Swinging maces proved to be one of the most lethal booby traps used by the Viet Cong because they usually struck the victim in his torso or head.\n\nYou may wonder how the Viet Cong didn't fall into these traps themselves, especially considering how well-camouflaged they were. Basically, they created a code of natural formations that would clue friendly forces into the presence of a trap. For example, twigs thrown across the ground in a certain way meant there was a mace trap just ahead, though it appeared like normal jungle brush to American soldiers.\n\nThe Viet Cong actually used this code to study the success of their traps and adjust their trapping strategy accordingly. They often returned to trap locations to see which had been triggered and how.\n\nTo a certain extent, US sappers picked up and learned these codes. They were sometimes even able to use the codes against the Viet Cong, creating fake trap corridors that altered enemy troop movements or removing the warning codes, causing the Vietnamese soldiers to fall into their own traps. Generally, though, the Viet Cong kept this system one step ahead of their enemy, and booby traps remained a powerful physical and psychological factor throughout the war.\n\n## Key Takeaways\n\n- The Vietnam War, lasting from 1955 to 1973, was emotionally devastating for American troops, with 10% experiencing PTSD.\n- Viet Cong's unconventional tactics, including booby traps, significantly impacted American soldiers psychologically and physically.\n- Punji sticks, bamboo spikes often poisoned with feces, were a simple yet effective trap causing severe injuries and infections.\n- The Viet Cong used various traps like bamboo whips, cartridge traps, and snake pits to inflict both physical and psychological harm.\n- American soldiers faced constant fear due to the ingenuity and brutality of Viet Cong's booby traps, which were often camouflaged and unpredictable.\n\n## Frequently Asked Questions\n\n### What were Punji sticks?\n\nPunji sticks were a simple but effective booby trap used by the Viet Cong in the Vietnam War.

Tiger traps involved suspending a large board with spikes and weights in the trees. A tripwire would release the board, causing it to crash down and impale or crush the enemy soldier. ### What was a mudball mine? A mudball mine was a grenade with its firing pin pulled and encased in dried mud or clay that held down the safety lever. Movement nearby could jostle the firing pin free, detonating the grenade. ### How did the Viet Cong use flags as booby traps? The Viet Cong booby-trapped their flag poles to explode when the flag was lowered, knowing that American troops often sought war trophies. ### What were swinging maces? Swinging maces were makeshift weapons made from a round core of wood, metal, or straw with spikes attached. They were suspended from a tree and released by a tripwire, swinging down to impale enemy soldiers. ### How did the Viet Cong avoid their own booby traps? The Viet Cong used a code of natural formations to clue friendly forces into the presence of a trap, such as twigs thrown across the ground in a certain way to indicate a mace trap. ### What psychological impact did booby traps have on American soldiers? Booby traps were as destructive psychologically as they were physically, causing long-term emotional scars and contributing to the high rates of PTSD among Vietnam veterans. ## Sources - [Original Side Projects video: The Most Terrifying Traps Used in the Vietnam War](https://www.youtube.com/watch?v=ur10aOGVTNs) - [https://www.ptsd.va.gov/understand/common/common_veterans.asp](https://www.ptsd.va.gov/understand/common/common_veterans.asp) - [https://en.wikipedia.org/wiki/Vietnam_War](https://en.wikipedia.org/wiki/Vietnam_War) - [https://www.historyhit.com/the-most-dangerous-viet-cong-booby-traps/](https://www.historyhit.com/the-most-dangerous-viet-cong-booby-traps/) - [https://www.armymuseum.co.nz/punji-spikes/](https://www.armymuseum.co.nz/punji-spikes/) - [https://en.wikipedia.org/wiki/Punji_stick](https://en.wikipedia.org/wiki/Punji_stick) - [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1477501/pdf/annsurg00444-0042.pdf](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1477501/pdf/annsurg00444-0042.pdf) - [https://www.facebook.com/VietnamVeteransofAmerica/posts/pfbid02Zu1tbxQ87vSbkDbYLHC4YgbJyFHvFodYUupyUkxXBbWYcbMmTSeY7QyWB2zTTGCLl](https://www.facebook.com/VietnamVeteransofAmerica/posts/pfbid02Zu1tbxQ87vSbkDbYLHC4YgbJyFHvFodYUupyUkxXBbWYcbMmTSeY7QyWB2zTTGCLl) - [https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/](https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/) - [https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html](https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html) - [https://en.wikipedia.org/wiki/Cartridge_trap](https://en.wikipedia.org/wiki/Cartridge_trap) - [https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html](https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html) - [https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/](https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/) - [https://en.wikipedia.org/wiki/Craspedocephalus_gramineus](https://en.wikipedia.org/wiki/Craspedocephalus_gramineus) - [https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html](https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html) - [https://en.wikipedia.org/wiki/Tunnel_rat](https://en.wikipedia.org/wiki/Tunnel_rat) - [https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/](https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/) - [https://roreyandcody.wordpress.com/tag/vietnam-war-museum/](https://roreyandcody.wordpress.com/tag/vietnam-war-museum/) - [https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html](https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html) - [https://coffeeordie.com/booby-traps-vietnam-war](https://coffeeordie.com/booby-traps-vietnam-war) - [https://www.historyhit.com/the-most-dangerous-viet-cong-booby-traps/](https://www.historyhit.com/the-most-dangerous-viet-cong-booby-traps/) - [https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/](https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/) - [https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/](https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/) - [https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html](https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html) - [https://www.historyhit.com/the-most-dangerous-viet-cong-booby-traps/](https://www.historyhit.com/the-most-dangerous-viet-cong-booby-traps/) - [https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/](https://www.wearethemighty.com/popular/8-of-terrifying-booby-traps/) - [https://www.5rar.asn.au/weapons/boobytraps.htm](https://www.5rar.asn.au/weapons/boobytraps.htm) - [https://www.wearethemighty.com/articles/how-the-viet-cong-managed-to-avoid-being-victims-of-their-own-booby-traps/](https://www.wearethemighty.com/articles/how-the-viet-cong-managed-to-avoid-being-victims-of-their-own-booby-traps/) - [https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html](https://www.warhistoryonline.com/vietnam-war/viet-cong-booby-traps.html) ## Related Coverage
