The audible sound of a gun discharging, also known as the muzzle report or gunfire, may have two sources: the muzzle blast itself, which manifests as a loud and brief "pop" or "bang", and any sonic boom produced by a transonic or supersonic projectile, which manifest as a sharp whip-like crack that persists a bit longer.
The word can connote either the sound of a gun firing, the projectiles that were fired, or both. For example, the statement "gunfire came from the next street" could either mean the sound of discharge, or it could mean the bullets that were discharged. It is better to be a bit more specific while writing however.
The sound ranging operators used equipment that augmented human hearing. Using the gun flash, the flash crew would determine a bearing to the gun using a theodolite or transit. The sound detection crew would determine the difference in time between the gun flash and the sound of the gun, which was used to determine the range of the gun.
Imagine walking through a forest and suddenly hearing the sounds of a machine gun firing. You’d probably drop and take cover, only to discover that the source of the sound is actually the one-of ...
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...

A 7.62×51mm NATO crimped blank cartridge. The appearance of a blank cartridge can give a false sense of safety. Although blank cartridges do not contain a bullet, precautions are still required because fatalities and severe injuries have resulted on occasions when blank cartridges have been fired at very close ranges.
Light machine gun: a class of machine gun often defined as being designed for carry and use by a single operator and firing the same intermediate-power cartridge as other soldiers in a unit. Live fire exercise or LFX : Any exercise that simulates a realistic scenario for the use of specific equipment.
