YaATW2KT: The Second Mexican-American War

Those people caught in thermobaric weapon attacks typically die from the pressure wave and/or asphyxiation before their (now dead) bodies are incinerated.
This is still a very unpleasant way to die, you're either crushed by the over-pressure or the vacuum created by all that oxygen being rapidly consumed ruptures your lungs.
In some circumstances, the fuel burns but does not detonate, then you see deaths by incineration.
