Navy SEALs are the U.S. Navy's primary special operations force and a component of the Naval Special Warfare Command. They are trained to engage in direct raids or assaults on enemy targets, conduct reconnaissance missions, and take part in action against terrorist groups. Their main functions include conducting small-unit special operation missions in various environments such as maritime, jungle, urban, arctic, mountainous, and desert. SEALs are typically ordered to capture or kill high-level targets, or to gather intelligence behind enemy lines. They receive training in performing duties like insertions, extractions, capture, and intelligence gathering
