Gunboat
A gunboat is like a big boat with guns on it that is used during a war or a conflict to protect an area near the water. Just like how a police officer uses a car to patrol the streets to keep people safe, a gunboat is used to patrol the water and keep other boats or ships from doing bad things. The guns on the gunboat are really big and can shoot really far to protect the area. Imagine a big boat with really big guns, patrolling the water to protect everyone nearby.
