Thermobaric weapons use a mixture of fuel, air and powered metal to create a massive fireball and explosion. These munitions are very useful against bunkers or buildings.

Note that the term "Vacuum bomb" is a misnomer. The bomb does not create a vacuum like in space, although it does use the surrounding oxygen in the air for use in the oxidization process.
