Wearing a mask like a devil in everyone's nightmare,
this is the Danish Frogman Corps,
is an elite special forces in the Royal Danish Navy
that has a unique way of Camouflage.
The Frogman Corps was established on 17 June 1957,
and on 1 July 2015 it transferred from the Royal Danish Navy
to the newly established Special Operations Command.
The Frogman Corps' primary role is reconnaissance,
but it is also tasked with assaulting enemy ships,
sabotage of fixed installations,
advanced force and maritime anti-terrorism tasks.
It also performs special operations work on land,
including anti-terrorism and anti-criminal work.
The Frogman Corps supports the police with matters
that demand highly specialized diving
and can also benefit from the frogmen's skills,
for example when underwater installations must be inspected.
The Frogman Corps trains at the Torpedo Station at Kongsøre,
and works through a long series of course,
such as Combat swimmer course for three weeks,
advanced scuba diving,
Rescue swimmer course,
and Survival course.
The basic Frogman Course is nine months.
Each year 500–600 applicants start the course
and less than a dozen complete all nine months.
The Frogman Corps were involved in operations in Afghanistan
under the Task Force K-Bar in 2001 - 2002
and operation in Iraq.
From 2008 until the end of 2014,
the Danish Frogman Corps was involved in counter-piracy operations
as part of Operation Ocean Shield.
On 5 February 2010,
ten Frogman Corps members aboard HDMS Absalon (L16)
conducted a counter-piracy mission in the Gulf of Aden,
approaching the Antigua and Barbuda-flagged merchant vessel Ariella
by rigid hull inflatable boat which had been hijacked by six armed Somali pirates.
They scaled the side of the ship and freed the 25 crew,
who had locked themselves in a secure room,
and continued to search the vessel for the pirates who had however fled.
