The Type A Ko-hyoteki class was a class of Japanese midget submarines (Kō-hyōteki) used during World War II. They had hull numbers but no names. For simplicity, they are most often referred to by the hull number of the mother submarine. Thus, the midget carried by I-16-class submarine was known as I-16's boat, or "I-16tou."
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 South African Navy (SA Navy) is the naval warfare branch of the South African National Defence Force.

Italian submarine Scirè was an Adua-class submarine, built in 1930s which served during World War II in the Regia Marina. It was named after a northern region of Ethiopia, at the time part of Italian East Africa.
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.
Operation Paraquet was the code name for the British military operation to recapture the island of South Georgia from Argentine military control in April 1982 at the start of the Falklands War.
From 31 May to 8 June 1942, during World War II, Imperial Japanese Navy submarines made a series of attacks on the Australian cities of Sydney and Newcastle. On the night of 31 May – 1 June, three Ko-hyoteki-class midget submarines, each with a two-member crew, entered Sydney Harbour, avoided the partially constructed Sydney Harbour anti-submarine boom net, and attempted to sink Allied warships. Two of the midget submarines were detected and attacked before they could engage any Allied vessels. The crew of M-14 scuttled their submarine, whilst M-21 was successfully attacked and sunk. The crew of M-21 killed themselves. These submarines were later recovered by the Allies. The third submarine attempted to torpedo the heavy cruiser USS Chicago, but instead sank the converted ferry HMAS Kuttabul, killing 21 sailors. This midget submarine's fate was unknown until 2006, when amateur scuba divers discovered the wreck off Sydney's northern beaches.
Operation Daisy was a military operation conducted from November 1–20, 1981 by the South African Defence Force and South West African Territorial Force (SWATF) in Angola during the South African Border War and Angolan Civil War. This conflict was sparked when the South African Defence Force decided to try to halt the regroup of the active military branch of SWAPO, also known as the People's Liberation Army of Namibia.
I-30 was a Type B1 submarine of the Imperial Japanese Navy during World War II. After operating in the Indian Ocean she participated in a Yanagi mission, aimed at connecting Japan and Nazi Germany by submarine. She was the first Japanese submarine to reach Europe, arriving at Lorient, France in August 1942. I-30 returned to Singapore loaded with military technology and information, but hit a mine outside the harbour and sank. Only part of her cargo was salvaged.
German submarine U-735 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II.
I-124, originally named Submarine Minelayer No. 52 and then named I-24 from before her launch until June 1938, was an I-121-class submarine of the Imperial Japanese Navy that served during the Second Sino-Japanese War and World War II. During the latter conflict, she operated in support of the Japanese invasion of the Philippines and was sunk during anti-shipping operations off Australia in January 1942.
South Africa currently does not have a marine corps, though in the past it did. It was originally set up as a sub-branch of the South African Navy during the apartheid era, with the primary purpose of protecting the country's harbours (1951-1955). Then it was recreated in 1979 during the South African Border War as 1 Marine Brigade with the aim of serving as marine infantry (1979-1990). Today, the SAN Maritime Reaction Squadron is the closest analogue to a marine corps South Africa has.
The Raid on Souda Bay was an assault by Italian Royal Navy explosive boats on Souda Bay, Crete, during the first hours of 26 March 1941. The motor boats were launched by the destroyers Francesco Crispi and Quintino Sella on the approaches to the bay. After negotiating the boom defences, the small craft attacked the Royal Navy heavy cruiser HMS York and the Norwegian tanker Pericles. The Allied vessels were both sunk in shallow waters by the explosive charges and eventually lost.
Operation Kerslig was a South African Defence Force special forces raid on an oil refinery outside Luanda, Angola. The raid took place on 30 November 1981 by members of the 1 and 4 Reconnaissance Regiments.
SAS Outeniqua was a sealift and replenishment ship operated by the South African Navy between 1993 and 2004. During her operational career she conducted several "flag-showing" cruises to African ports and provided support for South Africa's Antarctic research program. Outeniqua was also the venue for unsuccessful peace talks between Zaire's President Mobuto Sese Seko and rebel leader Laurent Kabila in May 1997.

M24 Japanese Midget Submarine wreck site is a heritage-listed former midget submarine and now archaeological site located in unincorporated waters off Sydney's Northern Beaches in New South Wales, Australia. The Ko-hyoteki-class midget submarine was designed by the Imperial Japanese Navy and built from 1941 to 1942 by Kure Naval Yard or Ourazaki Naval Yard. The site was added to the New South Wales State Heritage Register on 7 December 2007.
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
Operation Lark was two special forces naval operations in 1978 conducted by members of the South African Navy (SADF), 4 Reconnaissance Regiment and Rhodesian SAS during the South African Border War. Its objective was the assassination of Robert Mugabe at his residence in Maputo, Mozambique.
