" The tanks had fired high-impulse thermobaric shells. Two blips flashed across nine hundred meters in the blink of an eye. The shells contained a slurry of propylene oxide mixed with a finely powdered explosive. As simple microchips in the warheads registered that they had reached the target, they cracked open and dispersed their contents over the heads of the enemy infantrymen. The soldiers had a split second to see the bright orange cloud, but no time to escape before small incendiary fuses sparked a titanic blast. At the epicenter, temperatures soared to 3,000 degrees Centigrade and overpressure reached 430 psi. The men, the plant life—in fact, every living thing and most of the inanimate objects within the blast area—ceased to exist. Even the air was incinerated, creating a vacuum that pulled in more burning fuel and loose objects from a wide margin around the point of impact. Anyone who might have survived—even momentarily, by dint of having been entirely submerged—would have encountered the true meaning of hell, having been simultaneously flash-boiled, asphyxiated, and cooked from within as the blazing fuel–air mix penetrated all nonairtight objects.
