Helocasting is an airborne technique used by small unit, special operations forces, also practiced extensively by the US Army's light infantry units, to insert into a military area of operations. The small unit is flown, by helicopter, to a maritime insertion point. Once there, the aircraft assumes an altitude just above the water's surface and an airspeed of 10 knots (19 km/h) or less. Team members then exit the aircraft and enter the water.
In some cases, depending upon the mission parameters and the aircraft used, personnel may be inserted along with an inflatable boat for over-the-horizon operations. When a fully inflated boat is transported and inserted with personnel, this type of operation is known as a "hard duck". In cases where a fully inflated boat cannot be accommodated by the aircraft, it can be partially deflated for transit and inflated at the insertion point by means of a foot pump. This type of operation is known as a "soft duck". If inflation to any degree is not feasible, a "rolled duck" may be performed.
Once team members are in the water, they may swim to the objective or, in the case of a "hard duck", "soft duck", or "rolled duck", conduct an over-the-horizon transit to the objective, via inflatable boat. [1]
The Royal Antigua and Barbuda Defence Force is the armed forces of Antigua and Barbuda. The RABDF has responsibility for several different roles: internal security, prevention of drug smuggling, the protection and support of fishing rights, prevention of marine pollution, search and rescue, ceremonial duties, assistance to government programs, provision of relief during natural disasters, assistance in the maintenance of essential services, and support of the police in maintaining law and order.
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word qajaq.
Whitewater is formed in a rapid, when a river's gradient changes enough to generate so much turbulence that air is trapped within the water. This forms an unstable current that froths, making the water appear opaque and white.
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space structures employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, billowing, and suction.
A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity unsinkable boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along the boat’s topsides. The design is stable, light, fast and seaworthy. The inflated collar acts as a life jacket, ensuring that the vessel retains its buoyancy, even if the boat is taking on water. The RIB is an evolutionary development of the inflatable boat with a rubberized fabric bottom that is stiffened with flat boards within the collar to form the deck or floor of the boat.
An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurised gas. For smaller boats, the floor and hull is often flexible, while for boats longer than 3 metres (9.8 ft), the floor typically consists of three to five rigid plywood or aluminium sheets fixed between the tubes, but not joined rigidly together. Often the transom is rigid, providing a location and structure for mounting an outboard motor.
The F470 Combat Rubber Raiding Craft (CRRC), also known as the "Combat Rubber Reconnaissance Craft," is a specially fabricated rubber inflatable boat often used by the U.S. Navy, U.S. Marine Corps, the U.S. Army, and others. The CRRC is typically called "Zodiac," referring to the boat's manufacturer, Zodiac Milpro leading to this boat being the name "Zodiac" has become synonymous with the CRRC in popular culture.

A dive boat is a boat that recreational divers or professional scuba divers use to reach a dive site which they could not conveniently reach by swimming from the shore. Dive boats may be propelled by wind or muscle power, but are usually powered by internal combustion engines. Some features, like convenient access from the water, are common to all dive boats, while others depend on the specific application or region where they are used. The vessel may be extensively modified to make it fit for purpose, or may be used without much adaptation if it is already usable.
A personal flotation device is a piece of equipment designed to assist a wearer to keep afloat in water. The wearer may be either conscious or unconscious.
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.
Rover is a plot device from the 1967 British television program The Prisoner, and was a crucial tool used to keep 'prisoners' from escaping the Village. It was depicted as a floating white balloon that could coerce, and, if necessary, incapacitate inhabitants of the Village. In one incident, it even killed a person, but it is not clear whether the ability to kill was a normal feature of Rover or if this incident was a malfunction. Several aspects of the Rover device were not explained, presumably left to the imagination of the viewer.
The Radio Reconnaissance Platoon is a specially trained element of a United States Marine Corps Radio Battalion. A Radio Reconnaissance Team (RRT) was assigned as the tactical signals intelligence collection element for the Marine Corps Special Operations Command, Detachment One. Regular RRTs also participate in SOC operations during Marine Expeditionary Unit, or MEU(SOC), deployments.
The Special Patrol Insertion/Extraction (SPIE) system was developed as a means to rapidly insert and/or extract a reconnaissance patrol from an area that does not permit a helicopter to land. SPIE has application for rough terrain as well as water inserts/extracts. It is an adaptation of the Vietnam War-era STABO rig.
Air-sea rescue is the coordinated search and rescue (SAR) of the survivors of emergency water landings as well as people who have survived the loss of their seagoing vessel. ASR can involve a wide variety of resources including seaplanes, helicopters, submarines, rescue boats and ships. Specialized equipment and techniques have been developed. Military and civilian units can perform air-sea rescue.
A survival suit, or as it is more accurately and currently referred to as, an immersion suit, is a special type of waterproof dry suit that can protect the wearer from hypothermia if immersed in cold water, after abandoning a sinking or capsized vessel, especially in the open ocean. Immersion suits usually have built-in feet (boots), and a hood, and either built-in gloves or watertight wrist seals. Suits manufactured by several manufacturers also include an inflatable pillow which is permanently attached high on the back, or an inflatable tube that is attached with zippers at two points on the chest, each side of the main zipper, and circles the back. When inflated, both of these devices provide enhanced stability to the wearer, so that, if conscious, allows them to have enhanced stability with the head above water, and the ability to keep wind and seas from striking the face. The inflation tube is routed from the inflatable pillow over the left shoulder of the user, and secured in a loop on the chest. Some immersion suits are manufactured with straps/clips and hooks to allow multiple survivors to attach to one another in the water. This practice keeps survivors together. As well, some suits are manufactured with built-in hoisting lanyards, to allow easier retrieval from vessels with a higher seaboard, that may have manual or mechanical hoisting capabilities.
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety.
A rescue lifeboat is a boat rescue craft which is used to attend a vessel in distress, or its survivors, to rescue crew and passengers. It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, inflatable or rigid-inflatable combination hulled vessels.
The Marine Branch (1918-1986) was a branch of the Royal Air Force (RAF) which operated watercraft in support of RAF operations. Just days after the creation of the RAF itself, the Marine Craft Section (MCS) was created with the transfer of Royal Navy Air Service (RNAS) vessels and personnel to the new service. Originally tasked with the support of RNAS, and later RAF, seaplanes, Marine Craft Section was to achieve its greatest size during the Second World War, and achieved fame for its role in air-sea rescue operations. After the war MCS was granted full branch status on 11 December 1947, however post war the role of the new branch became greatly reduced with the end of the British Empire, the withdrawal of flying boats from service, and the increasing use of helicopters in air-sea rescue. The branch was disestablished on 8 January 1986.
