What does frogmen mean?
Frogmen are trained underwater swimmers, especially military or naval divers who carry out difficult tasks beneath the surface. The word can refer to reconnaissance teams, demolition specialists, rescue workers, and other personnel involved in underwater operations. In modern usage it most often has a practical, operational, and often military or maritime character. Although “divers” is the broad everyday equivalent, “frogmen” suggests specialized training, teamwork, and readiness for dangerous underwater work. The plural is irregular in English: the singular is “frogman,” while the plural adds “-men” rather than “-mans.” The term became especially prominent in the history of naval warfare and underwater demolition, and it continues to evoke elite swimmers moving stealthily through the sea.
