Tracer ammo is like special bullets that light up and leave a trail of light behind them when they are fired from a gun. It is made up of a small amount of special material called a pyrotechnic that ignites when the bullet is fired. This makes it easy for people to see the path of the bullet as it travels through the air towards its target.
It is usually composed of two types of ammunition; one is the regular bullet and the other is the tracer bullet. The tracer bullet has a small pyrotechnic material that is ignited by the burning gunpowder inside its cartridge. When the bullet exits the barrel of the gun, the pyrotechnic burns very brightly, leaving behind a visible trail that makes it easier to track the direction of the bullet.
Tracer ammo is commonly used by the military during combat or training, as well as by law enforcement officers during training exercises. It helps them to train better by being able to see the path of their bullets, adjust their aim, and improve their accuracy.
In summary, tracer ammo is a special kind of bullet that lights up when it is fired from a gun, making it easier to see where it is going. It's used mostly by soldiers and policemen for training and during combat situations to improve accuracy.
