Military
To attack an enemy’s “soft targets”—undefended objects, houses, public buildings—with concentrated artillery with the intent of demoralising civilians and having them pressure their leaders into surrender. Initially defined as use of land-based heavy guns, bombardment has evolved into an equivalent of aerial bombing with the advent of military aviation.
 
Radiation physics
