Jagdstaffel 18 was a group of special pilots who flew airplanes during World War I. They were part of the German military and their main job was to protect German planes from being attacked by enemy planes.
The pilots who were part of Jagdstaffel 18 were really good at flying and were trained to be able to spot enemy planes from far away. They would then fly their own planes really fast and shoot at the enemy planes to try and get them to go away or stop attacking the German planes.
Jagdstaffel 18 was one of the best groups of pilots in the whole war and they were responsible for shooting down a lot of enemy planes. They were really important because without them, the German planes might not have been able to fly safely and do their jobs.
Overall, Jagdstaffel 18 was a group of really brave and skilled pilots who worked hard to protect their own planes and their country during World War I.
