Napalm, short for Napthatic-Palmatic Acid is basically a jellied gasoline. It was used in against infantry troops in the open both in bombs and in flamethrowers. It was also used in quantity in the firebombings of Dresden and Tokyo.
Imagine flaming jellied gasoline sticking to everything and it's nearly impossible to extinguish.
I love the stuff.
