There are many kinds of soldiers including Marines and flyers. There are also sailors who go upon the seas to protect us. Soldiers, and sailors, learn to fight against the people who want to hurt the United States, or whatever country they represent. They train hard and long and hope that they will not have to fight. But, if they do have to fight, they are prepared to fight and even give up their lives for their country if they must.
Soldiers do an important job during a war and during times of peace.
By doing the good job that they do, they make countries that don't like us afraid to hurt us for fear that they will be hurt by our soldiers. That way the soldiers keep the peace that allows us to go about our business and live quietly with our neighbors and without fear. Harry's mother is a soldier. He sat in bleachers with a large number of people including his little brother and his father, also a soldier. Far away from the bleachers, an explosion threw dirt and dust and smoke into the air.
