What is the primary use of the 5.56mm frangible cartridge by the Air Force?

The primary use of the 5.56mm frangible cartridge by the Air Force is for training on ranges with strict surface danger zone restrictions. This type of ammunition is designed to disintegrate upon impact, significantly reducing the risk of ricochet and limiting potential hazards in environments where live fire training occurs close to populated or sensitive areas. It allows military personnel to conduct necessary training without posing a high safety risk to themselves or others in the vicinity.

Utilizing frangible cartridges is particularly important in urban or confined environments where traditional ammunition could result in injuries or damage due to ricochets and stray rounds. This approach helps to maintain safety while still allowing for realistic training conditions that prepare service members for potential real-world scenarios.
