Lieutenant general

Lieutenant general, lieutenant-general and similar (abbrev Lt Gen, LTG and similar) is a three-star military rank (NATO code OF-8) used in many countries. The rank traces its origins to the Middle Ages, where the title of lieutenant general was held by the second in command on the battlefield, who was normally subordinate to a captain general.

In modern armies, lieutenant general normally ranks immediately below general and above major general; it is equivalent to the navy rank of vice admiral, and in air forces with a separate rank structure, it is equivalent to air marshal. A lieutenant general commands an army corps, made up of typically three army divisions, and consisting of around 60,000–70,000 soldiers (U.S.).

The seeming incongruity that a lieutenant general outranks a major general (whereas a major outranks a lieutenant) is due to the derivation of the latter rank from sergeant major general, which was also subordinate to lieutenant general. In some countries (e.g. France and Italy), the ranks of corps general or lieutenant colonel general are used instead of lieutenant general, in an attempt to solve this apparent anomaly – these ranks are often translated into English as lieutenant general.

Joint Task Force

A Joint Task Force is a "joint" (multi-service) ad hoc military formation. The task force concept originated with the United States Navy around the beginning of the Second World War in the Pacific.

"Combined" is the British-American military term for multi-national formations.

There are two ways in which a U.S. or U.S.-allied task force may be assigned a number. The first is the originally naval scheme promulgated and governed by the U.S. Military Communications-Electronic Board, chaired by the Joint Staff J6. Task force numbers allocated under this scheme form the majority of the listings below.

Task force

A task force (TF) is a unit or formation established to work on a single defined task or activity. Originally introduced by the United States Navy, the term has now caught on for general usage and is a standard part of NATO terminology. Many non-military organizations now create "task forces" or task groups for temporary activities that might have once been performed by ad hoc committees.

Naval

The concept of a naval task force is as old as navies, but the term came into extensive use originally by the United States Navy around the beginning of 1941, as a way to increase operational flexibility. Prior to that time the assembly of ships for naval operations was referred to as fleets, divisions, or on the smaller scale, squadrons, and flotillas.

Before World War II ships were collected into divisions derived from the Royal Navy's "division" of the line of battle in which one squadron usually remained under the direct command of the Admiral of the Fleet, one squadron was commanded by a Vice Admiral, and one by a Rear Admiral, each of the three squadrons flying different coloured flags, hence the terms flagship and flag officer. The flag of the Fleet Admiral's squadron was red, the Vice Admiral's was white and the Rear Admiral's blue. (The names "Vice" (possibly from advanced) and "Rear" might have derived from sailing positions within the line at the moment of engagement.) In the late 19th century ships were collected in numbered squadrons, which were assigned to named (such as the Asiatic Fleet) and later numbered fleets.
