During Vietnam War, booby traps weren’t the only terrifying things that the American troops had to watch out for and be wary about in the Vietnam jungles. The jungles themselves were already packed with surprises that no one would ask for, and no, it’s not Bigfoot. They’re other things that nightmares are made of.

The Indo-Chinese Tiger

Yep, you read that right.  Vietnam once had tigers lurking in the jungle.  While none have been seen in Vietnam since the late 1990s, this tiger had a range that went from southern China into Laos, Cambodia, and even Vietnam. So it wasn’t just Charlie that could be hunting for you in the bad bush, but Shere Khan from Jungle Book looking to make a meal out of you if you got separated from your unit.

Try not to act surprised that this leftover dinosaur from the Late Miocene Age lives in a country like Vietnam with swamps, rivers and a long coastline on the Pacific. These suckers can get up to two tons and 18ft in length and fear absolutely nothing. Because of their huge size and highly aggressive nature they have been hunted out or relocated to areas away from people in the United States and Australia but not in Africa and Asia where they inhabit rivers and river deltas in the thousands.  They are incredible swimmers in terms of endurance and can cross large bodies of open water. Scientists believe crocodiles swam from Africa to the Western and Southern Hemispheres about 7 million years ago, covering as much as 300 miles a day with the help of ocean currents. Their tough armored skin on an 18-foot body would make them a match even for a large shark like the Great White, their tremendous bite force would crush the cartilage structure of just about any shark that tried to take a bite out of them
