Molotov Truck

You, and possibly your buddies, are in a jam. There's some obstacle in your way, be it a large group of people, a wall, or even a space station, and you don't possess the necessary conventional firepower. You use what's at your disposal. In a lot of cases it may be easy to get your hands on a vehicle of some sort: car, truck, boat, space ship, what have you. usually these vehicles have some form of fuel, or you might have a spare grenade or other explosives. Why not put them together? Like ice-cream and chocolate syrup.

The gist of it is that the vehicle acts as a weapon on its own and as a delivery system for some form of explosive; Such as, the vehicle's own fuel (set off by a primary explosion or combustion), high explosives, kegs of black powder, a nuke, whatever fits the situation. NOT Every Car Is a Pinto!

The name came from a Dark Heresy game. The group had to assault an Arbites (police) station, and they had driven there in a truck. One character had randomly asked for bed sheets and flexible plastic tubing. So, instead of charging into a building full of prepared and well-armed Arbites, they stuck a bed sheet in the gas tank, let it soak a little, lit it, and put a cinder block on the gas petal. It drove itself straight into the front of the building, like a giant motorized Molotov Cocktail. It took a minute, but KABOOM! made the whole thing a lot easier.

 * A variation appears in Call of Duty: World At War, where your squad encounters a truck with fuel barrels in it, at the top of a hill, facing an enemy encampment. Rather than lighting the whole thing on fire, you puncture one of the barrels while a squadmate puts the truck in neutral and lets it careen downhill, and then ignites the fuel trail instead.

 * Brander, or the "Fire ship" often used in the age of wooden ships. It was simply an old, wreck-like ship, with a skeleton crew, set aflame and rammed into the center of the enemy fleet For Massive Damage. Preferrably filled with as much powder as it could carry, but even when not, once the brander's riggings snag on another ship's, there's a good chance that its target's powder-magazine will shower everything with burning remnants soon.
