Thermobaric weapon

A thermobaric weapon, aerosol bomb, fuel air explosive, or vacuum bomb is a type of explosive that uses oxygen from the surrounding air to create a high-temperature explosion.
This can be launched as a rocket or dropped from an airplane as a bomb.
Effects.
In 2000, Human Rights Watch quoted United States authorities, on how the blast's "kill mechanism against living [things or] targets is unique—and unpleasant... What kills is the pressure wave, and more importantly, the subsequent [vacuum or] rarefaction, which ruptures the lungs... If the fuel [burns or] deflagrates but does not [... explode], victims will be severely burned and will probably also [... breathe] the burning fuel. [... The] most common FAE fuels [or fuel-air explosion fuels], ethylene oxide and propylene oxide, are highly toxic"; Breathing unexploded FAE adds to the risk of (related) death.
