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.
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 non-tactical missions. They were predecessors of the navy's current SEAL teams.
Force Reconnaissance (FORECON) are United States Marine Corps deep reconnaissance companies that supply military intelligence to the command element of the Marine Air-Ground Task Force (MAGTF). Force Reconnaissance companies unlike USMC division reconnaissance report to the Marine expeditionary force (MEF) and provide direct action and deep reconnaissance during large-scale operations.
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.
The Naval Diving Unit (NDU), also referred to as the Naval Divers, is the special forces formation of the Republic of Singapore Navy (RSN) responsible for conducting special operations from sea, air, and land. The formation is made up of six squadrons, specialising in explosive ordnance disposal, underwater demolition, maritime security operations, and combatant craft operations.
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.
The United States Marine Corps Reconnaissance Battalions are the special operations assets of Marine Air-Ground Task Force that provide division-level ground and amphibious reconnaissance to the Ground Combat Element within the United States Marine Corps. Division reconnaissance teams are employed to observe and report on enemy activity and other information of military significance in close operations. The Military Occupational Specialty code for Reconnaissance Marine is 0321.
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.
A United States Navy diver refers to a service personnel that may be a restricted fleet line officer, civil engineer corps (CEC) officer, Medical Corps officer, 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 US employs divers in several branches of the armed forces, including the navy, army, marines, air force and coast guard.
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.
The United States Marine Corps Reconnaissance Training Company trains Marines in the amphibious environment as a Reconnaissance Marine, MOS 0321. It is under the Advanced Infantry Training Battalion (AITB) of the School of Infantry (West), Marine Corps Base Camp Pendleton, California.
The two amphibious/ground reconnaissance assets of the United States Marine Corps, Division and Force Reconnaissance, are generally trained in the same aspect and environment of intelligence collection for a Marine Air Ground Task Force (MAGTF) Commander, regardless of their difference in tactical area of responsibility (TAOR). However, in light of their distinctive responsibilities in their assigned areas of operations—whereas Division Recon conducts close and distant operations, Force Recon conducts deep operations—these two separate reconnaissance assets manage their own training protocols to fit their mission-oriented objectives.
Ground Intelligence Officer is a primary military occupation code of a U.S. Marine Corps intelligence officer. Ground intelligence officers serve as staff officers and commanders in the operating forces and are responsible for analyzing intelligence and planning, deployment and tactical employment of ground surveillance and reconnaissance units. The Ground Intelligence Officer can be a Recon Marine after their training is done.
Army engineer divers are members of national armies who are trained to undertake tasks underwater, including reconnaissance, demolition, and salvage. These divers have similar skills and qualifications as professional divers. Army divers use both surface supplied "Hard hat" and SCUBA to perform their missions. In the United States Army, they are members of the Corps of Engineers. In the British Army, they may be Royal Engineer Divers or Commando Engineer Divers.
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.
The 101st Amphibious Reconnaissance Battalion, known as the Sea Dragon Frogmen; not to be confused with other frogman unit within the ROC Armed Forces which is the Amphibious Reconnaissance and Patrol Unit of the Republic of China Marine Corps, is a SCUBA trained combat swimming & diving as well as underwater demolitions focused special operations forces of the Republic of China Army.
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.
