Swimming

Swimming is the movement by humans or animals through water, usually without artificial assistance. Swimming is an activity that can be both useful and recreational. Its primary uses are bathing, cooling, travel, fishing, escape, and sport।

A frogman is someone who is trained to dive or swim in a military capacity which can include combat. Such personnel are also known by the more formal names of combat diver or combat swimmer. Strictly speaking, "combat swimming" refers to surface swimming without a breathing apparatus for the purposes of coastal or ship infiltration. Such actions are an historical form of "frogman" activity and an important feature of naval special operations.

In popular usage, the term '"frogman" might also refer to a civilian scuba diver. The word arose around 1940 from the appearance of a diver in shiny wetsuit and large fins. Though the preferred term by scuba users is "diver", the "frogman" epithet persists in informal usage by non-divers, especially in the media and often in reference to professional scuba divers such as in a police role. Also, some sport diving clubs include the word "Frogmen" in their names.

In the U.S. 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 Disposal (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 "special operations unit".

Many nations and some irregular armed groups deploy or have deployed combat frogmen.
