Okay kiddo, do you like swimming? The United States Military also has divers who swim underwater to do different jobs. Some of these jobs might be to remove objects like bombs or mines from the bottom of the ocean, or to fix a boat that is not working properly. They might even help find things that are lost in the water, like a person or a plane that crashed.
These military divers have to be trained very well. They need to learn how to swim very far and hold their breath for a long time. They also need to know how to use special equipment, like masks, fins, tanks of oxygen, and underwater cameras. It's important that they can communicate with each other while they are underwater, because it can be hard to hear things clearly when you are surrounded by water.
It's not always easy to be a military diver, but it's a really important job. They help keep us safe and make sure our boats and equipment work well.
