fire control

In military contexts, fire control refers to the strategic planning, preparation, and execution of firing upon targets. A crucial element of fire control is target acquisition, which historically relied heavily on visual observation from ground personnel, observation balloons, and aircraft.12

During World War I, technological advancements introduced methods like sound ranging and flash spotting for target acquisition. Sound ranging used microphones to detect the sound waves from fired guns, allowing for the triangulation of enemy positions. Flash spotting involved observers noting the azimuth of gun flashes to pinpoint enemy artillery. While flash spotting became less common with the advent of flashless propellants, sound ranging remained a significant target acquisition method for much of the 20th century. More recently, infrared sensors have enabled new forms of flash spotting.2
