When did frogmen become seals?

Frogmen, originally used to describe naval combat divers during World War II, evolved into the SEALs (Sea, Air, and Land teams) with the establishment of the U.S. Navy SEALs in 1962. The transition reflected a need for specialized forces capable of conducting unconventional warfare across various environments. The term "frogman" persisted informally, but the formal designation of SEALs represented a more structured and comprehensive approach to special operations.
