Medal for Service in War Overseas

Okay kiddo, sometimes when people go to fight in a war in another country, they do a really good job and deserve to be thanked for their hard work. So, a medal is like a fancy sticker that they are given to show how proud we are of them. It's a special way to say "thank you" for what they did to keep us safe. And sometimes, people collect medals because they are like a trophy or a prize for doing something important.
