Anyone who's ever deployed can tell you there's more to worry about in the field than just the enemy. While of course the North Vietnamese were the primary concern of American troops in the Vietnam War, just being in the jungle presented an entirely unexpected series of its own challenges – like giant centipedes.
Rumors persisted about things like fragging, rampant drug use, and even the appearance of Bigfoot in Vietnam. But when US troops weren't earning the Medal of Honor while completely stoned, they were fighting off things that only previously appeared in their nightmares.
1. Giant insects
Bring on the flamethrower.
As seen in the cover photo of this post, the creepy crawlers of the jungle have the space and the food necessary to grow to an insane level. That guy in the photo is Scolopendra subspinipes, also known as the Vietnamese centipede, Chinese redhead, or Jungle Centipede. It's extremely aggressive, and its venomous bite hurts like hell, sources say. But the fun doesn't stop with centipedes, giant scorpions were also known to bother American troops in bivouac.
2. Weaver ants
Imagine you're in some kind of tank or armored vehicle, busting down trees in the jungle when suddenly, you bust down the wrong tree, one filled with a nest of red ants. These buggers were reportedly immune to the issued bug spray and, given the choice between NVA small arms fire and dealing with red ants in the tank, tank crews would either bail on the tank or man the vehicle completely naked. They were often referred to as "communist ants" because they were red in color and never seemed to attack the Vietnamese.
3. Debilitating plants
Very pretty, but also what the KGB used to kill dissidents.
Troops in Vietnam were sometimes lifted right up out of troop carriers and other vehicles by low-hanging vines that seemed innocent at first, but as soon as they were touched, constricted around an unsuspecting driver, grabbing them by the arms or neck. They became known as the "wait-a-minute" vines. But that's just the beginning.
Vietnam's most beautiful trees and flowers are also its deadliest. Heartbreak Grass, Flame Lillies, Twisted Cord Flowers, and Bark Cloth Trees are all powerful enough to kill a human or cause blindness upon contact or accidental ingestion, which is more common than one might think.
4. Venomous snakes
Bring that flamethrower back over here.
You know what kinds of animals love a hot, humid place with lots of shade? Reptiles and amphibians, both of which Vietnam has in droves. Vietnam has so many snakes, American troops were advised to just assume they were all deadly – because most of them are. The country is filled with Cobras, Kraits, Vipers, and more. The snakes that weren't venomous were all giant constrictors, still very capable of murdering you in your jungle sleep.
5. Large wildlife
Yes, troops were mauled by tigers.
Since we're talking about giant jungle snakes, we should discuss the other giant creatures that inhabit the wilds of Vietnam. Southeast Asia is also home to aggressive tiger species, leopards, and bears. Those are just the traditional predators. There are also elephants, water buffaloes, and gaurs, giant cows, who will go on a murder rampage that an M-16 isn't likely to stop.
