Frogman
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. The term ''frogman'' is occasionally used to refer to a civilian scuba diver. Some sport diving clubs include the word ''Frogmen'' in their names. The preferred term by scuba users is ''diver'', but the ''frogman'' epithet persists in informal usage by non-divers, especially in the media and often referring to professional scuba divers, such as in a police diving role.

Frømandskorpset
The Frogman Corps ( da, Frømandskorpset) is the maritime special operations force of the Danish Defence part of Special Operations Command. On 1 July 2015, the Frogman Corps transferred from the Royal Danish Navy to the newly established Special Operations Command. History The Frogman Corps was established on 17 June 1957 based on the model of the United Kingdom's Special Boat Service, US Underwater Demolition Team, and Marinejegerkommandoen in Norway. Initially it was under the Danish Navy's Diving School at Flådestation Holmen (Naval Station Holmen, Copenhagen), but in 1972 it was made an independent unit, operationally under the submarine squadron. Role The Frogman Corps' primary role is reconnaissance, but it is also tasked with assaulting enemy ships, sabotage of fixed installations, advanced force and maritime anti-terrorism tasks. It also performs special operations work on land, including anti-terrorism and anti-criminal work. The Corps supports the police with mat ...

Underwater Demolition Team
Underwater Demolition Teams (UDT), or frogmen, were amphibious units created by the United States Navy during World War II with specialized non-tactical missions. They were predecessors of the navy's current SEAL teams. Their primary WWII function began with reconnaissance and underwater demolition of natural or man-made obstacles obstructing amphibious landings. Postwar they transitioned to scuba gear changing their capabilities. With that they came to be considered more elite and tactical during the Korean and Vietnam Wars. UDTs were pioneers in underwater demolition, Rebreather, closed-circuit diving, combat swimming, and midget submarine (dry and Wet sub, wet submersible) operations. They later were tasked with ensuring recovery of space capsules and astronauts after splash down in the Mercury program, Mercury, Gemini program, Gemini and Apollo program, Apollo space flight programs. Commando training was added making them the forerunner to the United States Navy SEAL progra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navy SEAL
The United States Navy Sea, Air, and Land (SEAL) Teams, commonly known as Navy SEALs, are the U.S. Navy's primary special operations force and a component of the Naval Special Warfare Command. Among the SEALs' main functions are conducting small-unit special operation missions in maritime, jungle, urban, arctic, mountainous, and desert environments. SEALs are typically ordered to capture or to kill high level targets, or to gather intelligence behind enemy lines. All active SEALs are members of the U.S. Navy. The CIA's highly secretive and elite Special Operations Group (SOG) recruits operators from SEAL Teams, with joint operations going back to the MACV-SOG during the Vietnam War. This cooperation still exists today, as evidenced by military operations in Iraq and Afghanistan. History Origins Although not formally founded until 1962, the modern-day U.S. Navy SEALs trace their roots to World War II. The United States Military recognized the need for the covert reconnaiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CCUBA
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, and, for covert military use by frogmen or observation of underwater life, eliminating the bubbles produced by an open circuit system and in turn not scaring wildlife being filmed. A rebreather is generally understood to be a portable unit carried by the user. The same technology on a vehicle or non-mobile installation is more likely to be referred to as a life-support system. Rebreather technology may be used where breathing gas supply is limited, such as underwater or in space, where the enviro ...

Special Amphibious Reconnaissance Corpsman
A Special Amphibious Reconnaissance Corpsman (SARC) is a United States Navy hospital corpsman who provides MARSOC and other USSOCOM units advanced trauma management associated with combatant diving and parachute entry. Traditionally, they are attached to the Marine Corps Force Reconnaissance companies to help support the Command Element of the Marine Air-Ground Task Force in special reconnaissance missions. Mission SARCs are trained and specialized in the same aspects of special operations as their counterparts: amphibious entry, deep recon and direct action. They are also capable of conducting detailed underwater ship-bottom searches. During operational status, the teams will then be dispersed evenly throughout the Marine Recon platoons; usually one SARC per platoon. SARCs have regularly acted as a point man, sharp shooter, radio operator, or even the team leader in the Marine Recon teams/platoons. More recently, SARCs are being deployed with Marine Special Operations Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Force Combat Controllers
United States Air Force Combat Control Teams, singular Combat Controller (CCT) ( AFSC 1Z2X1), are an elite American special operations force (specifically known as "special tactics operators") who specialize in all aspects of air-ground communication, including air traffic control, fire support (including fixed and rotary wing close air support), and command, control, and communications in covert, forward, or austere environments. Assigned to Special Tactics Squadrons and Special Tactics Teams along with Pararescuemen, Special Operations Reconnaissance, and Tactical Air Control Party (TACP) operators, Combat Controllers are an integral part of Air Force Special Operations Command (AFSOC), the Air Force component of United States Special Operations Command (USSOCOM), and of Joint Special Operations Command (JSOC). Trained in underwater and maritime operations, freefall parachuting, and many other deployment methods, Combat Controllers are often assigned individually or as a tea ...

Navy EOD
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 (or disposal) 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. EOD Technicians' missions take them to all environments, and every climate, in every part of the world. They have many assets available to arrive to their mission, from open- and closed-circuit scuba and surface supplied diving rigs, to parachute insertion from fixed-wing ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Scuba Set
A scuba set, originally just scuba, is any breathing apparatus that is entirely carried by an underwater diver and provides the diver with breathing gas at the ambient pressure. ''Scuba'' is an anacronym for self-contained underwater breathing apparatus. Although strictly speaking the scuba set is only the diving equipment that is required for providing breathing gas to the diver, general usage includes the harness by which it is carried, and those accessories which are integral parts of the harness and breathing apparatus assembly, such as a jacket or wing style buoyancy compensator and instruments mounted in a combined housing with the pressure gauge, and in the looser sense, it has been used to refer to all the diving equipment used by the scuba diver, though this would more commonly and accurately be termed scuba equipment or scuba gear. Scuba is overwhelmingly the most common underwater breathing system used by recreational divers and is also used in professional diving whe ...

Paul Boyton
Paul Boyton (often misspelled Boynton) (1848-1924), known as the ''Fearless Frogman'', was a showman and adventurer some credit as having spurred worldwide interest in water sports as a hobby, particularly open-water swimming. Boyton, whose birthplace is variously listed as Dublin or Pittsburgh, Pennsylvania, is best known for his water stunts that captivated the world, including crossing the English Channel in a novel rubber suit that functioned similarly to a kayak. As the founder of Sea Lion Park in 1895, Boyton is also known as the originator of the first modern amusement park with a fenced-in enclosure and admission charged at the gate. Early life and education Boyton attended Saint Francis University, Loretto, Pennsylvania. Eager for adventure at a young age, he reportedly joined the Union Navy during the American Civil War when he was 15, and in his young adulthood served stints with Benito Juárez's Mexican Navy and the French Franc-tireurs during the Franco-Prussian W ...

John Spence (frogman)
John Pitts Spence (June 14, 1918 – October 29, 2013) was an American diver for the United States Navy and World War II veteran who is widely credited as the country's first combat frogman. Spence was the first enlisted man to be recruited into a clandestine group, operated by General William "Wild Bill" Donovan of the Office of Strategic Services (OSS), which would become known as the frogmen. The group was a predecessor of the present-day United States Navy SEALs. The origin of the term "frogman" can be traced directly to John Spence. In an interview with maritime historian Erick Simmel, Spence explained that frogman first came into use while he was training in a green, waterproof suit. Spence recalled, "Someone saw me surfacing one day and yelled out, 'Hey, frogman!' The name stuck for all of us." Spence and the other men trained in underwater close combat techniques, demolition and stealth in order to destroy underwater emplacements and enemy ships during World War II. Spence ...

Professional Diving
Professional diving is underwater diving where the divers are paid for their work. 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. There are several branches of professional diving, the best known of which is probably commercial diving and its specialised applications, offshore diving, inshore civil engineering diving, marine salvage diving, hazmat diving, and ships husbandry diving. There are also applications in scientific research, marine archaeology, fishing and aquaculture, public service, law enforcement, military service and diver training. Any person wishing to become a professional diver normally requires ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
