The M982 Excalibur is a special kind of bomb that the military can use to hit targets very accurately from far away. It's actually a really smart bomb that uses a computer to help it find the right spot to hit. The bomb has a long range and can be fired from a big gun, a helicopter or a drone. Once it's in the air, the bomb's computer can measure things like wind and temperature to make sure it's going in the right direction. The bomb can even change its own path if it needs to. Finally, when it gets close to the target, it can use a GPS system to guide itself the rest of the way to hit the exact spot where it's instructions say to hit. It's a really cool bomb that is very helpful in keeping soldiers safe and hitting enemy targets with precision.
