Hey kiddo, have you heard of the military? They're the people who help protect our country and they have ranks to show how important they are. The higher the rank, the more responsibility they have.
So normally, a soldier can work their way up from the lowest rank, which is private, all the way up to a five-star rank, which is the highest. But there is something called a six-star rank! It's not really used anymore, but it's a special rank that is above the five-star rank.
Only two people have ever been given this six-star rank, and they were both during a really important time in history. Their names were George Washington and John Pershing, and they were both very important leaders in the military.
Nowadays, we don't really need a six-star rank because the five-star rank is already the highest and it's really rare for someone to achieve it. But it's still interesting to know about the history of the military and how they have different ranks to show how important and respected someone is.
