KGT 38: The Klingon military, of course, has a hierarchical structure of its own, with ranks and areas of authority spelled out explicitly. Various fleets and squadrons are loyal to various houses, though, as might be expected, the details of these alliances are subject to change. Within the Klingon Defense Force (tlhIngan Hubbeq), which includes the entire Klingon military apparatus, the highest officers tend to be members of influential houses, particularly the members of the ultimate military authority, the High Command (ra'ghomquv). KGT 51: The entirety of a government's military apparatus is its QI', usually translated simply as "military". The word is rather general in that it may apply to a nongovernmental military organization as well, such as that of a group of rebels. Though many Klingons themselves are apt to describe the Federation's Starfleet as a type of QI', this is not really an appropriate use of the term, since QI' refers to the military only, while the functions of Starfleet are scientific and diplomatic as well. This misapplication of the term may, in part, be responsible for the frequent misunderstandings between the Federation and the Empire. The official Klingon QI' is the Klingon Defense Force, or tlhIngan Hubbeq, which is run by the Klingon High Command, or tlhIngan ra'ghomquv. The Defense Force is subdivided into units known as yo' and nawlogh, traditionally translated as fleet and squadron, respectively, but the relationship between the two is not straightforward in terms of chain of command.
