Arctic star is a special medal that is given to people who serve in the Arctic region, which is an area around the North Pole where it is very cold and snowy.
Imagine you are playing outside in the winter and it is very cold and snowy. Now imagine that it is even colder and snowier in the Arctic, and there are no houses or stores around for miles and miles. It can be really tough to survive there because it is so cold and there are not a lot of resources.
Some people have to work in the Arctic, like soldiers and scientists. They might have to do things like build and repair equipment, explore the area, and keep people safe. These people are very brave and they have to work really hard in very difficult conditions.
The Arctic star medal is a way for people to recognize the bravery and hard work of those who served in the Arctic. It is a medal that is shaped like a star and has a picture of a polar bear on it. People who receive the medal can wear it on their uniform or display it at home as a way of showing that they did something amazing by working in the Arctic.
