Joint Terrorism Task Force

A Joint Terrorism Task Force (JTTF) is a partnership between various American law enforcement agencies that is charged with taking action against terrorism, which includes the investigation of crimes such as wire fraud and identity theft. The agencies that a JTTF comprises generally include the Federal Bureau of Investigation, other federal agencies (notably Department of Homeland Security components such as U.S. Coast Guard Investigative Service, U.S. Immigration and Customs Enforcement, U.S. Customs and Border Protection, the Transportation Security Administration, and the U.S. Secret Service as well as the Department of State's Diplomatic Security Service), state and local law enforcement, and specialized agencies, such as railroad police.

JTTFs engage in surveillance, electronic monitoring, source development and interviews in their pursuits. FBI task forces obtain written memoranda of understanding (MOUs) between participating law enforcement agencies. The FBI provides funds to pay for participating agencies' expenses, such as officer overtime, vehicles, fuel, cell phones, and related office costs.

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.

Terrorism

In its broadest sense, terrorism is any act designed to cause terror. In a narrower sense, terrorism can be understood to feature a political objective. The word terrorism is politically loaded and emotionally charged.

A broad array of political organizations have practised terrorism to further their objectives. It has been practised by both right-wing and left-wing political parties, nationalist groups, religious groups, revolutionaries, and ruling governments. The symbolism of terrorism can exploit human fear to help achieve these goals.

Origin of term

"Terrorism" comes from the French word terrorisme, and originally referred specifically to state terrorism as practiced by the French government during the 1793–1794 Reign of Terror. The French word terrorisme in turn derives from the Latin verb terrere (e, terreo) meaning "to frighten". The terror cimbricus was a panic and state of emergency in Rome in response to the approach of warriors of the Cimbri tribe in 105 BCE that the Jacobins cited as a precedent when imposing the Reign of Terror during the French Revolution. After the Jacobins lost power, the word "terrorist" became a term of abuse.

Joint

A joint or articulation (or articular surface) is the location at which bones connect. They are constructed to allow movement (except for skull, sacral, sternal, and pelvic bones) and provide mechanical support, and are classified structurally and functionally.

Classification

Joints are mainly classified structurally and functionally. Structural classification is determined by how the bones connect to each other, while functional classification is determined by the degree of movement between the articulating bones. In practice, there is significant overlap between the two types of classifications.

Terms ending in the suffix -sis are singular and refer to just one joint, while -ses is the suffix for pluralization.

An articulate facet is generally seen as a small joint, especially used when speaking of the joints of the ribs.

Structural classification (binding tissue)

Structural classification names and divides joints according to the type of binding tissue that connects the bones to each other. There are three structural classifications of joints:

Force

In physics, a force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.

The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time. If the mass of the object is constant, this law implies that the acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object

Related concepts to force include: thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque, which produces changes in rotational speed of an object. In an extended body, each part usually applies forces on the adjacent parts; the distribution of such forces through the body is the so-called mechanical stress. Pressure is a simple type of stress. Stress usually causes deformation of solid materials, or flow in fluids.
