Scuba diving is a very versatile sport. It has applications in a wide variety of fields, starting with personal, recreational, scientific and up to military. Some even consider it extreme because of the many risks it comes with. The recreational diving field has many specializations such as wreck diving, cave diving, deep diving or ice diving. Some divers might be professionally appointed or employed to perform underwater tasks. These divers work either part time, or full time, as instructors, instructor assistants, dive guides or dive masters. In some parts of the world, the divers’ community might be obliged by the government to follow certain rules, created especially for the safety and health of the clients, recreational or professional divers.
The high end professional specialty in diving is for the military. These divers have a long history and were once called frogmen. The training includes training in tactical capacities such as combat, while swimming or diving. Nowadays, they are also called combat divers, combatant divers or combat swimmers. They intervene in special operations for the army and the navy. Usually, divers are asked to infiltrate behind enemy lines, to place mines, use a manned torpedo, and dispose bombs.
