What is the purpose of the Flash-to-Bang Method?

The Flash-to-Bang Method is specifically designed to estimate the range to an explosion or gunfire, making it essential for various tactical assessments in military operations. The method operates on the principle that light travels faster than sound. When an explosion occurs, the observer sees the flash of light almost instantly, while the sound (the 'bang') follows at a slower speed. By counting the seconds between seeing the flash and hearing the sound, personnel can calculate the approximate distance to the source of the explosion or gunfire. This method provides vital information regarding the enemy's position, allowing for informed decision-making and tactical planning. Understanding this concept is crucial for Non-Commissioned Officers tasked with situational awareness and operational safety.
