One wave would drop high explosive to destroy buildings. Later
waves might have more anti-personnel oriented weaponry to kill
the firemen fighting the fires, while delayed HE might be designed
to sink deeper into the ground before exploding, thus rupturing
gas and water lines, for more

This sounds somewhat like Dohet's philosophy. Douhet suggested three waves of
bombers seperated by 30 minutes. The first wave dropped HE to knock down
walls, or entire buildings. Wave 2 carried incendiary to set fire to what was
not knocked down. Wave 3 carried chemical weapons to prevent the fire fighters
from being able to extinguish the fires.
