Military call sign

A military call sign is a special code name used by soldiers and military personnel to identify themselves over radios or other communication devices. It is like having a secret nickname that only other soldiers know you by. These call signs can be based on a person's name, their job in the military, or even a special skill they have.
For example, imagine your name is John Smith and you are a soldier who specializes in fixing airplanes. Your military call sign might be "Fixer" or "Airman Smith" instead of using your real name when communicating with other soldiers over the radio. This helps keep communication clear and concise and protects soldiers' identities during combat or other sensitive operations.
