Okay kiddo, so have you ever heard of the Marine Corps? They are a special branch of the United States military that focuses on fighting on land and sea.
Basically, Marines are soldiers who are trained to fight in places that are close to water, like beaches, islands or ships. They have special skills like swimming, boating, diving and using boats to get to different places.
Marines are very strong and brave because they have to face tough situations, like storms, big waves, and enemy attacks on the water. They are also trained to be disciplined and to work together as a team to get the job done.
In a way, they are like superheroes who protect our country's interests wherever they are needed, whether it's defending our nation’s coasts or fighting against enemy forces in other parts of the world.
