The name might give it away, but this special forces unit is a maritime corps forming part of the special operations force of the Danish Defence. Until 2015, the Frogman Corps was part of the Royal Danish Army, but then it moved under the Special Operations Command umbrella. Recruits need to complete several courses, namely: an advanced scuba diving course, a rescue swimmer course, a three-week combat swimming program, and a survival course. All in all, the duration of the training is nine months and only 12 out of 500-600 applications make it through the whole course. Only 311 men have completed the course since the unit’s establishment in 1957.
