Question: What type of boat is the HDMS Ejnar Mikkelsen, a boat in the sea-based branch of the Danish Defence force?
Context: The Royal Bahamas Defence Force (RBDF) is the navy of The Bahamas.  Since The Bahamas does not have an army or an air force, its navy composes the entirety of its armed forces.  Under The Defence Act, the Royal Bahamas Defence Force has been mandated to defend The Bahamas, protect its territorial integrity, patrol its waters, provide assistance in times of disaster, maintain order in conjunction with the law enforcement agencies of The Bahamas, and carry out any such duties as determined by the National Security Council.  The Defence Force is also a member of Caricom's Regional Security Task Force.  The task force has seen action in the United Nations mandate in Haiti 1994. The Defence Force Service Medal (DFSM) is an Australian Military award given for long service by permanent members of the Australian Defence Force.  It is part of the suite of defence force service awards introduced in 1982, which also included the Reserve Force Decoration (RFD, for officers of the Australian Defence Force Reserves) and the Reserve Force Medal (RFM, for non-commissioned members of the Reserve forces).  All three medals were replaced in 2002 with a single medal, the Defence Long Service Medal, which is now awarded to all permanent and reserve members irrespective of rank. HDMS "Ejnar Mikkelsen" is a Royal Danish Navy patrol vessel. The Defence Long Service Medal is an Australian Military award given for long service by permanent and reserve members of the Australian Defence Force, irrespective of rank.  It was introduced in 1998, and replaced the suite of defence force service awards introduced in 1982, which comprised the Defence Force Service Medal, the Reserve Force Medal and the Reserve Force Decoration. Ejnar Mikkelsen (23 December 1880 in Vester-Brønderslev – 1 May 1971 in Copenhagen), was a Danish polar explorer and author.  He is most known for his expeditions to Greenland. Admiral Tan Sri Dato' Sri Mohd Anwar bin Haji Mohd Nor, is the Chief of Defence Force, Malaysia.  He is the first Chief of Defence Force to be appointed from the Royal Malaysian Navy.  For over five decades previously, the Chief of the Defence Force had traditionally been a 4-star General from the Royal Malaysian Army.  Anwar broke the tradition by being appointed the first Navy Admiral to be promoted to Chief of Defence Force. Ejnar Mikkelsen Range (Danish: "Ejnar Mikkelsen Fjeld" ) is a mountain range in King Christian IX Land, eastern Greenland.  Administratively it is part of the Sermersooq Municipality. The Royal Danish Navy (Danish: "Søværnet" ) is the sea-based branch of the Danish Defence force.  The RDN is mainly responsible for maritime defence and maintaining the sovereignty of Danish, Greenlandic and Faroese territorial waters.  Other tasks include surveillance, search and rescue, icebreaking, oil spill recovery and prevention as well as contributions to international tasks and forces. Watkins Island is a low lying, ice-covered island 5 mi long, lying 3 mi SW of Lavoisier Island in the Biscoe Islands.  The island was first mapped by the French Antarctic Expedition under Jean-Baptiste Charcot, 1903–05 and 1908–10, but remained unnamed until resighted by the BGLE under Rymill, 1934–37.  He gave the name Mikkelsen Island after Ejnar Mikkelsen, Danish Arctic explorer.  In applying the name, Rymill was unaware of the existence of Mikkelsen Islands 75 mi southwestward, named in 1908–10 by Charcot.  To avoid confusion of the two, the UK-APC recommended in 1952 that the Rymill naming be amended.  The new name, Watkins Island, commemorates Gino Watkins, leader of the British Arctic Air Route Expedition, 1930–31.  A new feature, Mikkelsen Bay, has been named for Ejnar Mikkelsen. Mikkelsen Bay is a bay, 15 nmi wide at its mouth and indenting 10 nmi , entered between Bertrand Ice Piedmont and Cape Berteaux along the west coast of Graham Land, Antarctica.  First seen from a distance in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot, but not recognized as a large bay.  First surveyed in 1936 by the BGLE under Rymill, and resurveyed by the Falkland Islands Dependencies Survey in 1948-49.  The name was proposed by members of BGLE for Ejnar Mikkelsen, Danish Arctic explorer and Inspector for East Greenland, 1934-50.
