In the Pacific theater during World War II, Japanese soldiers expertly camouflaged themselves by digging trenches and covering them in brush. From that position, they could snipe and shoot at advancing U.S. soldiers undetected.
Spider trenches were almost impossible to spot out, and then even harder to storm.
So soldiers smoked them out, literally, by lighting them on fire with flamethrowers.
The Smithsonian grabbed one of the last WW2-era flamethrowers and showed us just how brutal it was.
Burning to death, man. It’s gotta be a bitch.
