Island Command Greenland

Island Command Greenland (Danish: Grønlands Kommando), or simply "GLK", was a Level.II authority responsible directly to the Defence Command. It was, among other things, responsible for the military defense of Greenland, maritime and sovereignty maintenance and enforcement, as well as search and rescue. Personnel assigned to the Danish liaison office at Thule Air Base (FOTAB) as well as the Sirius Patrol (Danish: Slædepatruljen SIRIUS) were also a part of the Greenland Command. Island Command Greenland was amalgamated with Island Command Faroes to a Joint Arctic Command on 31 October 2012.

It also functioned as NATO's Island Commander Greenland, formerly part of Allied Command Atlantic. ACLANT became Allied Command Transformation in 2003, and since then it was not clear exactly how the command now fits into the NATO Military Command Structure.
