A Combat Swimmer is a specialized military operative trained to conduct underwater missions. These missions often involve reconnaissance, demolition, and direct action against enemy targets. Combat swimmers are skilled in various swimming techniques and use specialized equipment, including diving gear and underwater weapons, to navigate and operate in aquatic environments. Combat swimmers typically belong to elite units, such as the Navy SEALs in the United States or frogmen in other countries. Their training includes physical conditioning, survival skills, and tactics for stealthy movement in water. This training enables them to perform effectively in diverse and challenging conditions, often behind enemy lines.
