# 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 (designated purpose) committees. In non-military contexts, working groups are sometimes called task forces.

## Military
### Naval

The concept of a naval task force or simply task force is as old as navies, and 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 flying a different command flag, hence the terms flagship and flag officer. The names "Vice" (second) 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.

### Army

In the U.S. Army, a task force is a battalion-sized (usually, although there are variations in size) ad hoc unit formed by attaching smaller elements of other units. A company-sized unit with an armored or mechanized infantry unit attached is called a company team. A similar unit at the brigade level is called a brigade combat team (BCT), and there is also a similar Regimental combat team (RCT).
In the British Army and the armies of other Commonwealth countries, such units are traditionally known as battlegroups.
The 1st Australian Task Force (1 ATF) was a brigade-sized formation which commanded Australian and New Zealand Army units deployed to South Vietnam between 1966 and 1972. More recently, Australian task forces have been designated to cover temporary support elements such the battalion-sized force which operated in Urozgan Province, Afghanistan from 2006 to 2013, and the Northern Territory Emergency Response Task Force.

Task Force Lethal prides itself as one of the Army's premier multi-task light Infantry units that has trained at home in the mountainous regions of the Rocky Mountains in Colorado and excels at high altitude warfare. The commandos of Task Force Lethal have remained one of the US Army's most elite task forces in the global War on Terror since the start in 2003.

## Government

In government or business a task force is a temporary organization created to solve a particular problem. It is considered to be a more formal ad hoc committee. A taskforce, or more commonly, task force, is a special committee, usually of experts, formed expressly for the purpose of studying a particular problem. The task force usually performs some sort of an audit to assess the current situation, then draws up a list of all the current problems present and evaluates which ones merit fixing and which ones are actually fixable. The task force would then formulate a set of solutions to the problems and pick the "best" solution to each problem, as determined by some set of standards. For example, a task force set up to eliminate excessive government spending might consider a "best" solution to be one that saves the most money. Normally, the task force then presents its findings and proposed solutions to the institution that called for its formation; it is then up to the institution itself to actually act upon the task force's recommendations.

## Business

In business, task forces are initiated similar to military situations to form an ad hoc group of persons that focus on a specific subject, which needs urgent addressing, resolutions or results. Subject-specific task forces are very common. NASA lessons contain information from different task forces.
