A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word frogman first arose in the stage name the "Fearless Frogman" of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit.
Professional diving is underwater diving where the divers are paid for their work. Occupational diving has a similar meaning and applications. The procedures are often regulated by legislation and codes of practice as it is an inherently hazardous occupation and the diver works as a member of a team. Due to the dangerous nature of some professional diving operations, specialized equipment such as an on-site hyperbaric chamber and diver-to-surface communication system is often required by law, and the mode of diving for some applications may be regulated.
Underwater divers may be employed in any branch of an armed force, including the navy, army, marines, air force and coast guard. Scope of operations includes: search and recovery, search and rescue, hydrographic survey, explosive ordnance disposal, demolition, underwater engineering, salvage, ships husbandry, reconnaissance, infiltration, sabotage, counterifiltration, underwater combat and security.
The Underwater Demolition Team (UDT), or frogmen, were amphibious units created by the United States Navy during World War II with specialized missions. They were predecessors of the Navy's current SEAL teams.
The diver insignia are qualification badges of the uniformed services of the United States which are awarded to servicemen qualified as divers. Originally, the diver insignia was a cloth patch decoration worn by United States Navy divers in the upper-portion of the enlisted service uniform's left sleeve during the first part of World War II, when the rating insignia was worn on the right sleeve. When enlisted rating insignia were shifted to the left sleeve in late World War II, the patch shifted to the upper right sleeve. The diving patch was created during World War II, and became a breast insignia in the late 1960s.
A clearance diver was originally a specialist naval diver who used explosives underwater to remove obstructions to make harbours and shipping channels safe to navigate, but the term "clearance diver" was later used to include other naval underwater work. Units of clearance divers were first formed during and after World War II to clear ports and harbours in the Mediterranean and Northern Europe of unexploded ordnance and shipwrecks and booby traps laid by the Germans.
United States Navy Explosive Ordnance Disposal technicians render safe all types of ordnance, including improvised, chemical, biological, and nuclear. They perform land and underwater location, identification, render-safe, and recovery of foreign and domestic ordnance. They conduct demolition of hazardous munitions, pyrotechnics, and retrograde explosives using detonation and burning techniques. They forward deploy and fully integrate with the various Combatant Commanders, Special Operations Forces (SOF), and various warfare units within the Navy, Marine Corps, Air Force and Army. They are also called upon to support military and civilian law enforcement agencies, as well as the Secret Service.
Underwater demolition is the deliberate destruction or neutralization of man-made or natural underwater obstacles, both for military and civilian purposes.
The Russian commando frogmen, informally called "commando frogmen" in civilian media, are a Russian Naval Spetsnaz unit under operational subordination to the Main Intelligence Directorate (GRU). It is the special forces unit of the Russian Naval Infantry and is composed of highly trained and elite marines within the Naval Infantry. By virtue of belonging to the Russian Naval Infantry, frogmen fall under the Coastal Troops of the Russian Navy service arm. The Russian Navy proper does not field any special forces or special operations units. Russian FSB special forces Alpha Group and Vympel also have frogman units in their respective naval components.
The United States Navy master diver is the highest warfare qualification obtainable by a member of U.S. Navy diving community. A master diver is an enlisted person who typically has the most experience and knowledge on all aspects of diving and underwater salvage.
A United States Navy diver may be a restricted fleet line officer, Civil Engineer Corps (CEC) officer, Medical Corps officer, an Unrestricted Line Officer who is qualified in Explosive Ordnance Disposal (EOD) Warfare (1140) or an enlisted who is qualified in underwater diving and salvage. Navy divers serve with fleet diving detachments and in research and development. Some of the mission areas of the Navy diver include: marine salvage, harbor clearance, underwater ship husbandry and repair, submarine rescue, saturation diving, experimental diving, underwater construction and welding, as well as serving as technical experts to the Navy SEALs, Marine Corps, and Navy EOD diving commands.
The Divers Group is the Portuguese Navy's sapper clearance diver unit. It was created in 2004 through the grouping of the several already existing diving subunits, to exercise administrative, logistical and operational control and management, maritime special operations capable, over all diver units and personnel. It groups under a single command, all previously existing Sappers Divers Units and Services.
Canadian Armed Forces (CAF) divers are specialists trained to conduct underwater operations within their respective environmental commands. Divers within the CAF are qualified in sub-categories of diving: Clearance Divers, Search and Rescue Technicians (SRT), Port Inspection Divers (PID), Ship's Team Divers, and Combat Divers.
The US employs divers in several branches of the armed forces, including the navy, army, marines, air force and coast guard.
Divers Institute of Technology (DIT) is a private, for-profit educational institution for the training of commercial divers and located in Seattle, Washington. Founded in 1968 in Seattle, Washington, Divers Institute of Technology is located on the North end of Lake Union near Gas Works Park in the Wallingford district.
The United States Navy Center for Explosive Ordnance Disposal and Diving (CENEODDIVE) is one of the eleven learning centers responsible for training explosive ordnance disposal technicians and divers in the United States. CENEODDIVE is stationed on Naval Support Activity Panama City (NSA PC) in Florida and forms a part of the Naval Education and Training Command. With the exception of the Great Lakes learning site, CENEODDIVE is the only inter-service learning center.
The United States Air Force Combat Diver Course—administratively known as the 350th Battlefield Airmen Training Squadron, Det 2—is held at the Navy Diving Salvage and Training Center, Naval Support Activity Panama City and trains Pararescuemen, Combat Rescue Officers, Combat Controllers, and Special Tactics Officers to conduct and participate in special operations diving missions.
Special Forces Underwater Operations (SFUWO) is the term for United States Army Special Forces combat operations involving the use of underwater infiltration methods. These typically involve the use of closed circuit dive equipment to infiltrate a beach landing site (BLS) undetected. The US Army Special Forces, also known as Green Berets have been conducting maritime operations and underwater operations since their founding in 1952. Currently, each company within a Special Forces Group mans, trains, equips, and deploys a SFUWO Operation Detachment Alpha (SFOD-A). These twelve-man teams train for SFUWO as their primary infiltration method when conducting one of their missions of unconventional warfare, direct action, counter-terrorism, foreign internal defense, among others.
Underwater Construction Teams (UCT) are the United States Navy Seabees' underwater construction units numbered 1 and 2 that were created in 1974. A team is composed of divers qualified in both underwater construction and underwater demolition. Possible tasks can be: battle damage repairs, structural inspections and assessments, demolition of waterline facilities or submerged obstructions, installation of submerged surveillance systems, or harbor and channel clearance. As needed, teams may test and or evaluate new or existing aquatic systems or equipment. Extending construction, whether vertical or horizontal, beyond the shoreline and waterline is their specialty. Reflecting Seabee tradition, teams are expected to execute underwater construction anywhere, anytime, under any conditions.
