Okay kiddo, do you know what a group of people is? It's like when you and your friends play together. Now, imagine if you and your friends were in charge of protecting your town from bad guys. That's what a militia is.
A non-permanent active militia means that it's a group of people who only come together when they need to protect their town or country. It's like if your town had a big festival and your parents needed help to keep everyone safe. They could ask people in the town to join the non-permanent active militia for that day.
The good thing about a non-permanent active militia is that they are not always together, which means they can go back to their normal lives when they don't need to protect anyone. But when they're needed, they can quickly come together to keep people safe.
It's important to know that being part of a militia is a big responsibility, and people who join must be trained to use weapons, follow rules, and work together as a team.
