Okay sweetie, so a military saint is someone who is remembered for doing really great things in a war or battle a long, long time ago. These people are special because they showed bravery, kindness, and faith in difficult situations where many other people might be scared or mean.
When people think about military saints, they might think about people like Saint George, Saint Joan of Arc, or Saint Michael the Archangel. These are all people who we remember for their courage, their strength, and their goodness.
Now, just because someone is a military saint doesn't mean that they were perfect or that everything they did was good. They were human, just like you and me, so they probably made mistakes and did things they regretted too. But we still remember them because they did something really important that helped other people, and that's a very special thing.
So when we hear about military saints, we think about how they were brave and strong and tried to help others, even in hard times. And we can learn from them and try to be like them, by being kind and courageous and doing good things for others, just like they did.
