Flame fougasse

A flame fougasse is kind of like a big squirt gun for fire. Imagine if you mixed gasoline with some thick goopy stuff, put it in a container with a hole in the bottom, and then lit a match by that hole. When you push a button, the goopy stuff comes out of the hole and ignites, shooting a stream of fire in one direction.

People use flame fougasses to defend against things like tanks or groups of bad guys. If they think a tank is coming, they can set up a flame fougasse in its path. When the tank gets close, they push the button and fire shoots towards the tank. The heat and flames don't usually smash the tank, but it can make the operators inside scared and blind them for a bit, which gives defenders time to shoot the tank with their own weapons.

The goopy stuff inside a flame fougasse is often mixed with chemicals like powdered aluminum, which makes it burn hotter and for longer. People can also add things like nails, shards of metal, or even broken glass to the goop, which makes the fire shoot out shrapnel and can hurt people or damage equipment.

Overall, flame fougasses are kind of like big, fiery squirt guns that people use to defend their homes or fight off enemy armies.
