(Redirected from Frogmen)
:''This page describes a type of
scuba diver. For other uses of the word 'frogman', see
Frogman (disambiguation)''
'Frogman' is a popular term for a
scuba diver. The word arose around
1940 from the appearance of a diver in shiny wetsuit and with large fins on his feet. The term preferred by
scuba users is 'diver', but the word "frogman" persists in usage by non-divers, especially in the media, often to refer to professional scuba divers in organizations such as the police.
Usual usage of the word "frogman" also tends to imply diving for action, often in combat; such divers are also sometimes called 'combat diver' or 'combat swimmer'.
A few
sport diving clubs have included the word "Frogmen" in their names.
In the US Military, divers trained in scuba or
CCUBA who deploy for military assault missions are called "combat swimmers". This term is used to refer to the
Navy SEALs, the Marine Recon swimmers, the Army Ranger swimmers, and the Navy Explosive Ordnance Dispoal (EOD) units.
In Britain,
police divers have often been called "police frogmen". The first British police diver was a policeman who, needing to search underwater for evidence or a body, did not use a
drag but went home and fetched his sport scuba gear. See also
Ian Edward Fraser.
Some countries' frogman organizations include a translation of the word "frogman" in their official names, e.g.
Denmark's "Frømandskorpset" and
Norway's "Froskemanskorpset"; others call themselves "combat divers" or similar. Others call themselves by indefinite names such as "special group 13" and similar.
Many nations and some irregular armed groups use or have used combat frogmen.

See
anti-frogman techniques for details of detecting and combatting unwelcome frogman and
scuba diver incursions.
Types of armed-forces divers
'Military diving' is a branch of
professional diving carried out by
armed forces. They may be divided into:
★ Combat / assault divers.
★ Armed forces work divers (called
Clearance Divers in the
Royal Navy and
Royal Australian Navy), who do general work underwater.
★ Armed forces work divers who are trained in defusing
mines and removing other explosives underwater.
These groups may overlap, and the same men may serve as assault divers and work divers, as in the Australian
Clearance Diving Team (RAN).
Frogman training
Training armed forces divers, including combat divers, is far harder, longer, and more complicated than civilian sport scuba diver training, typically takes several weeks full-time, and the trainees must be at full
armed forces fitness and discipline at the start. It needs much higher levels of fitness, and during the course there is often a high elimination rate of trainees who do not make the grade. For more details see the articles on each nation's frogman group below and their external links.
This contrasts with civilian sport scuba diving training which tends to be one evening a week, being 30 to 60 minutes
swimming pool time, followed by two hours or so of dry meeting (often in a social-
club-type environment with an open
bar). The general environment at sport dives is liable to encourage what a naval diver-trainer would call "a casual tourist-type attitude to being underwater", rather than a disciplined attitude of obeying orders and not being distracted; some naval diver-trainers prefer, or will only accept, trainees who have no previous scuba diving experience.
[1]
For example, the
PADI Open Water Diver (the most basic rank) course takes 5 dives in a
swimming pool and 4 dives in open water (i.e.
sea,
lake, etc.); after the course the qualified diver is allowed to dive to 18 meters = 59 feet depth. The next step (
Advanced Open Water Diver) allows him to dive to 40 meters (130 feet) maximum, which is considered safe for civil scuba diving.

Equipment
For scuba diving gear in general, see
Scuba set.
Breathing sets
Frogmen's breathing sets on covert operations should have particular features.
★ Some are needed because they may need to swim fast and far.
★ Some are needed to avoid detection.
★ Sometimes patrol divers may have to be sent down to find or arrest submerged suspect divers. For reasons stated in
Anti-frogman techniques#Sending other frogmen against them, underwater fights between divers are much rarer in reality than in fiction, and thus suitability of the frogman's kit for "diver to diver combat" is less important than some other features when designing it; but the point is considered here for completeness.
USA frogmen's rebreathers tended to have the breathing bag on the back before enclosed backpack-box rebreathers became common.
Features needed
A frogman's breathing set should:
★ Be as silent as possible in use.
★ Have a
full face diving mask:
★
★
★ To let frogmen communicate underwater.
★
★
★ It is less easily knocked off underwater.
★
★
★ It is much less easily lost if the frogman goes unconscious underwater.
★
★ And see
here. It should have as little as possible (e.g. an excessively bulky or projecting set/air valve) that can catch on things or that an attacker could easily grasp.
★ Be a dull color to avoid being seen from out of the water. Many are black, but the Russian
IDA71's backpack box is mostly dark green. No large bright-colored badges or manufacturer's logos.
★ Contain as little iron or steel as possible, to avoid detection by
magnetic sensors. This is also useful when the frogmen have to remove or defuse
mines underwater.
★ Be as light and agile as possible:
★
★ Be well
streamlined, and as small and light as possible for the dive duration. With a combat diver this may mean removing safety features such as an open-circuit
bailout that would add bulk. Long trailing hoses (e.g. regulator hoses) are easily fouled and or pulled at and add to drag. If an underwater fight, or a quick need to escape, develops, agility and lack of cumbersomeness could be vital. This applies to:
★
★
★ Streamlining in straight swimming, as he may have to swim fast and far.
★
★
★ Streamlining when be rolls over and twists about.
★
★ The diver's
inertia when he must roll over quickly.
★
★ The risk of snagging on things in dark water, or being taken hold of by. The
Russian IDA71 military and naval rebreather is a good example here.
★ Have a long dive duration.
★ The front of the frogman's abdomen should be clear so he can easily climb in and out of small boats or over obstacles, particularly out of the water.
★ Its breathing bag should be toughened against stabbing and scratches, or safely inside a hard backpack box.
★ All controls should be where the frogman can easily reach them, and not projecting. Turning the usual type of sport diving scuba's air off or on is easy for an attacker from above but difficult or impossible for the diver himself (and has been known to happen by itself when a diver pushes through thick
kelp), unless the cylinder or cylinders are mounted inverted. However, that needs more pipework, and it is easy to bump the valvework on things, including when taking the set off.
★ Its working parts and breathing tube or tubes should be safe from snagging on things in dark water, and from attack in an underwater fight, including in the risk of being "jumped" from above.
★
★ Long trailing breathing tubes or regulator hoses may snag on things in dark water and can easily be grasped and pulled.
★
★ Older
Siebe Gorman-type
rebreathers (see
Siebe Gorman CDBA) had one breathing tube, which was in front of the chest and easier for the frogman to keep track of.
Not open-circuit scuba
As a result, the frogman's breathing set should be
fully closed circuit rebreather, preferably not
semi-closed circuit and certainly not
open-circuit scuba, because:
★ Open-circuit scuba makes large amounts of bubbles, showing where the diver is.
★ Open-circuit scuba makes noise (on exhalation, and
regulator valve intake hiss as the diver breathes in) showing
underwater listening devices where the diver is.
★
★ There have been experiments with making released air or gas come out through a
diffuser, to break the bubbles up; this may sometimes work with the small amounts of gas that are sometimes released by rebreathers, but open-circuit scuba releases so much gas at every breath that a diffuser large enough to handle it without making breathing difficult would be too bulky and would interfere with
streamlining. Holding the breath to avoid making noise at critical moments is not recommended and very risky: see
diving hazards and precautions
★ The bulk of an open-circuit set makes the diver heavy and cumbersome in rolling over and changing course or speed.
★ The dive duration of open circuit sets is much shorter than the dive duration of naval rebreathers, in proportion to bulk. However, some "technical diving" rebreathers are very burdened with safety devices such as inflatable flotation and open-circuit
bailout. (Some modern rebreathers, such as the
Draeger, are lighter.) The rebreathers which are the most compact in proportion to dive duration are
oxygen rebreathers, which are depth limited to about 8 meters = 26 feet due to the
oxygen toxicity risk.
Link to French Wikipedia image of frogman with "Oxygers" rebreather
★ The common sport open-circuit scuba set is not recommended for a fight against a trained naval or combat diver, because in any sort of underwater combat, a man with a large
aqualung has a high
rotation-inertia and is very
unstreamlined in the twisting and turning involved in fighting and straight swimming, and his maneuvering is slowed critically compared to a man with a light streamlined rebreather with all parts close to his body.
Combat frogmen sometimes use open-circuit scuba sets during training and for operations where being detected or long distance swimming are not significant concerns.
The Russian IDA71
The
Russian IDA71 military and naval rebreather is a typical frogman set:
★ Its working parts are in a hard smooth rounded metal backpack casing which has little that can snag on things or be easily grasped and pulled at. There is no mass of projecting valvework behind his neck to cause hydrodynamic drag and for an attacker to grasp.
★ Its only external control is its on/off switch, which is on its right edge near the bottom where he can reach it easily, and does not stick out.
★ It does have looping breathing tubes like an old-type
aqualung, but these originate well apart next to where they come over his shoulders and do not have to reach across from the back of his neck. They can be strapped to the shoulder straps so they do not float up into big vulnerable loops behind the shoulders.
★ When the frogman comes out of water quickly, the holes in the casing let contained water drain quickly, so he is quickly rid of the weight of that water.
★ In oxygen rebreather mode it is said to last 4 hours on a filling.
Masks
Most frogmen use a
full face diving mask instead of separate mouthpiece and mask. The older type of British frogman's and naval
diving mask was full face and had a mouthpiece inside it.
Some frogmen use a mouthpiece and noseclip or a mouth-and-nose (oro-nasal) breathing mask instead of a diving mask with eye windows, and special
contact lenses to correct the vision
refraction error caused by the eyeballs being directly submerged. This is to avoid a
searchlight or other lights reflecting off the mask window and thus revealing his presence, but it exposes the
eyeballs to any
pollution,
poison, or
organisms in the water.
The United States military has adopted
Oceanic/
Aeris's "
Integrated Diver Display Mask". It is a basic "Heads-Up Display" that lets divers monitor depth, bottom time, tank pressures, and related information while leaving their hands free for other tasks.
Fins
Another problem with a frogman who may have to come ashore and operate on land is the awkwardness of walking on land in
fins, unless he plans to discard his kit and return to base by some other way than by diving, or if the frogmen plan to take and hold a position on land until other troops arrive. Some sport diving fins have the blade angled downwards for more effective swimming, but this makes walking on them more awkward.
The usual solution is for the frogman to take his fins off and carry them, but that takes time and occupies a hand carrying them unless he can clip them in to his kit or thread an arm through the fins' straps.
Another type of fin that frogmen could use would have a lockable hinge which on land can be unlocked to let the fin blade hinge up out of the way when walking.
The first type of British naval swimming fin had a short blade which was even shorter at the big toe side: this made walking on land easier for such purposes as creeping up on a sentry from behind on land, but reduced swimming speed.
Diving suits
The frogman's diving suit should be a tough scratch-and-cut-resistant
drysuit (perhaps reinforced with
kevlar), and not a soft foam
wetsuit. A wetsuit can be worn under the drysuit as a warm
undersuit. In very warm water, a thin tough drysuit can be worn with no
undersuit.
★ For Bomb Disposal Operations, Canadian Naval Divers wear Bomb suits.
It should not have obvious bright colored patches,
unit badges or the suit's maker's
advertising. Diving sea-
police types, however, may find that a unit badge is useful.
Tools and weapons carried underwater
Weapons that can be carried by a frogman include:
★ Knife: standard weapon.
★ A
speargun has been seen advertised in circumstances suggesting its use for combat and not for fishing.
★ Firearms:
★
★ Russian
APS underwater rifle
★
★ Russian
ASM-DT Underwater Assault Rifle
★
★ Russian
SPP-1 Underwater Pistol
★
★
Heckler & Koch P11 Underwater Pistol
★
★ Canadian
Diemaco C7 and C8 assault rifles
★ Many types of explosives may be used:
★
★
C-4,
C13 grenade, and
clay explosives
★
★ And, most famously, the
limpet mine.
★ Other tools include
net-cutters.
Transport for frogmen
Frogmen may approach their site of operation and return to base in various ways including:
★ Swimming all the way.
★
Canoes.
★ Being dropped off and/or picked up by fast
Rigid-hulled inflatable boats.
★ In
World War II,
Italian and
British frogmen used
manned torpedoes to carry them to their targets. Some nations still keep manned torpedoes.
★ Canadian Naval Divers use the Phantom Remote Operated Vehicle(ROV),the SeaDoo Sea Scooter,TAYUT
General Purpose Boat
FDU(P),Yard Diving Tender (YDT) Sooke,and the
YDT 11
FDU(P).
★ The
Subskimmer and similar.
★ Midget
submarines such as the
X-craft, the
SDV or the US Advanced SEAL Delivery System
ASDS which frogmen can exit and return to through an
airlock.
★ Full-sized
submarines which frogmen can exit and return to, sometimes through a special
airlock or through one of the sub's
torpedo tubes. These two methods, like all methods, need precautions:
this link (in Russian) describes a risky incident in diving from a submerged submarine: the sub was neutrally buoyant at the start, and the first frogman
airlocking changed the sub's buoyancy, and the sub started to float up; in later dives the sub's captain ballasted the sub well to keep the sub on the seabed while frogmen were coming out or in.
★ More powerful versions of sport-diving
diver-tugs. Unmodified sport-diving
diver-tugs are usually not powerful enough or not long enough duration on a battery recharging.
★ The
Protei 5 and similar. See
Diver Propulsion Vehicle.
★ Some frogmen are trained to
parachute in to their site of operation. The backpack box of the
Russian
IDA71 frogman's rebreather has two metal clips to fasten to a parachute harness.
Types of frogman operations
★ Amphibious assault: stealthy deployment of land or boarding forces. The vast majority of Combat Swimmer missions are simply to get "from here to there" and arrive suitably equipped and in sufficient physical condition to fight on arrival. The deployment of tactical forces using the arrival by water to assault land targets,
drilling platforms, or surface ship targets (as in boardings for seizure of evidence), is a major driver behind the equipping and training of combat swimmers. The purposes are many, but include feint and deception, anti-
drug,
law enforcement, anti-
terrorism, and anti-
proliferation missions.
★ Sabotage: This includes putting
limpet mines on ships.
★ Clandestine surveying: Surveying a beach before a troop landing, or other forms of unauthorized underwater surveying in denied waters. The article
"Riding on Proton" by Afonchenko (in Russian) may describe in passing a
Soviet Bloc frogman
infiltration into
South Korean sea.
★ Clandestine underwater work, e.g.:
★
★ Recovering underwater objects.
★
★ Clandestine fitting of monitoring devices on underwater communication cables in enemy waters.
★ Investigating unidentified divers, or a sonar echo that may be unidentified divers. Diving sea-police work may be included here. See
anti-frogman techniques.
★ Checking
ships,
boats, structures, and
harbors for
limpet mines and other sabotage; and ordinary routine maintenance in war conditions. If the inspection divers during this find attacking frogmen laying mines, this category may merge into the previous category.
★ Underwater
mine clearance and
bomb disposal.
Mission descriptions
The U.S. and UK forces use these official definitions for mission descriptors:
★ '
Stealthy' - Keeping out of sight (e.g. underwater) when approaching the target.
★ '
Covert' - Carrying out an action which the enemy may become aware of, but it cannot easily be discovered who or what did it. Covert action often involves military force which cannot be hidden once it has happened. Stealth on approach, and frequently on departure, may be used.
★ '
Clandestine' - It is intended that the enemy does not find out then or afterwards that the action has happened. Installing
eavesdropping devices is the best example. Approach, installing the devices, and departure are all to be kept from the knowledge of the enemy. If the operation or its purpose is exposed, then the actor will usually make sure that the action at least remains "covert", or unattributable: e.g. ("''...the
secretary will disavow any knowledge of your actions.''")
Derivative word usages
★ Some
scuba diving clubs have an entry class called "
Tadpoles" for younger children who want to start scuba diving.
★
Royal Navy men have a slang term "pond life" to mean civilian sport divers.
Errors about frogmen found in public media
Wrong use of the word "frogman"
A new English translation of the book ''Twenty Thousand Leagues Under the Sea'' uses the word "frogman" uniformly and wrongly to mean a diver in
standard diving dress or similar, to translate
French ''scaphandrier''.
Supposed ancient scuba divers/frogmen
Ancient
Assyrian stone carvings show images which some have supposed to be frogmen with crude breathing sets. However, the "breathing set" was merely a
goatskin float used to cross a river, and its "breathing tube" was to inflate it by mouth. See
timeline of underwater technology.
Mistakes in fiction
Aqualungs
Many
comics have depicted combat frogmen and other covert divers using two-cylinder twin-hose open-circuit
aqualungs. All real covert frogmen use
rebreathers because the stream of bubbles from an open-circuit set would give away the diver.
Many aqualungs have been
anachronistically depicted in
comics in stories set during
World War II, when in reality aqualungs were unknown outside
Jacques-Yves Cousteau and his close associates in
Toulon in south
France. Although some aqualungs were smuggled out of occupied France during the war (these may have been
Commeinhes aqualungs), the aqualung for the most part was not a player in combat in
World War II. The movie
The Frogmen also made this mistake, using three-
cylindered aqualungs.
DESCO were making three-cylinder
constant flow sets that lacked the
demand valve of the aqualung, but they were rarely deployed in the war, the preferred system being the
rebreather developed by Dr.
Christian J. Lambertsen.
Drawing and artwork
There have been thousands of drawings (mostly in
comics, some elsewhere) of combat frogmen and other scuba divers with two-cylinder twin-hose
aqualungs shown wrongly with one wide breathing tube coming straight out of each cylinder top with no regulator, far more than of twin-hose aqualungs drawn correctly with a regulator, or of combat frogmen with rebreathers. See for the correct layout.
This recent painting or CGI-type image on a website advertising the CSDS-85
frogman-detector sonar shows (bottom left corner) a frogman using
open-circuit scuba complete with bubbles carrying a
flying-saucer-shaped object which is likely meant to be a
limpet mine.
Movies and fiction
Frogman-type operations have featured in many
comics,
books, and
movies. Some try to reconstruct real events; others are completely fictional. Some make mistakes as described above. Examples are:
★ The 1951 film ''
The Frogmen'', made by
Twentieth Century Fox, shows some
United States frogman operations against the
Japanese in
World War II, but with wrong kit (see above).
★ Listed at
Human torpedo#Movies and fiction.

United States Navy SEALs in fiction.
History
In ancient
Roman and
Greek times, etc, there were many instances of men swimming or diving for combat, but they always had to hold their breath, and had no diving equipment, except sometimes a hollow plant stem used as a
snorkel. See the first part of the page at
this link (in Portuguese).
The first known frogmen-type operations using breathing apparatus were by the
Italian Decima Flottiglia MAS, which formed in 1938 and was in action first in 1940. See
Timeline of underwater technology and each of the nations' frogman unit links below.
