Grip (job)

In the U.S. and Canada, grips are lighting and rigging technicians in the filmmaking and video production industries. They constitute their own department on a film set and are directed by a key grip. Grips have two main functions. The first is to work closely with the camera department to provide camera support, especially if the camera is mounted to a dolly, crane, or in an unusual position, such as the top of a ladder. Some grips may specialize in operating camera dollies or camera cranes. The second main function of grips is to work closely with the electrical department to create lighting set-ups necessary for a shot under the direction of the director of photography.

In the UK, Australia and most parts of Europe, grips are not involved in lighting. In the "British System", adopted throughout Europe and the British Commonwealth (excluding Canada), a grip is solely responsible for camera mounting and support.

The term "grip" is from the early era of the circus. From there it was used in vaudeville and then in today's film sound stages and sets. Some have suggested the name comes from the 1930s–40s slang term for a tool bag or "grip" that these technicians use to carry their tools. Another theory is that in the days of hand-cranked cameras, it was necessary for a few burly men to hang on to the tripod legs to stop excessive movement of the camera. These men became known as the "good grips"—as they were constantly being instructed to "keep a good grip on the tripod".

Grip (gymnastics)

Grips are devices that are worn on the hands of artistic gymnasts when performing on various gymnastics apparatus. They are worn by female gymnasts on the uneven bars, and by male gymnasts on the high bar, and still rings; is rarely seen that a male gymnast uses grips for parallel bars. They are used to enhance the gymnast's grip on the apparatus, and also to reduce (but not eliminate) the friction that can cause painful blisters and rips, in which outer layers of skin separate and tear away from the hand.

Grips are optional and are not used by all gymnasts. Some athletes substitute sports tape or gauze for grips, while others use bare hands. Gymnasts typically apply powdered chalk (typically magnesium carbonate) to their grips, or to their hands if not using grips.

Construction

A grip consists of a wide strip of leather joined to a wrist strap. The leather strip, which covers and protects the palm of the hand, is approximately five centimeters wide and has finger holes at one end. On properly fitted grips, the finger holes will be positioned at the first knuckles of the inserted fingers.

Special Air Service

The Special Air Service (SAS) is a special forces unit of the British Army. The SAS was founded in 1941 as a regiment, and later reconstituted as a corps in 1950. This special forces unit undertakes a number of roles including covert reconnaissance, counter-terrorism, direct action, hostage rescue and human intelligence gathering.

The corps presently comprises 22 Special Air Service Regiment, the regular component, under the operational command of United Kingdom Special Forces, and 21 (Artists) Special Air Service Regiment (Reserve) and 23 Special Air Service Regiment (Reserve), which are reserve units under the operational command of 1st Intelligence, Surveillance and Reconnaissance Brigade.

The Special Air Service traces its origins to 1941 and the Second World War, and was reformed as part of the Territorial Army in 1947, named the 21st Special Air Service Regiment (Artists Rifles). 22 Special Air Service Regiment, part of the regular army, later gained fame and recognition worldwide after successfully assaulting the Iranian Embassy in London and rescuing hostages during the 1980 Iranian Embassy siege, lifting the regiment from obscurity outside the military establishment.

23 Special Air Service Regiment (Reserve)

23 Special Air Service Regiment (Reserve) (23 SAS(R)) is a regiment of the British Army Reserve. Together with 21 Special Air Service Regiment (Artists) (Reserve) (21 SAS(R)), it forms the Special Air Service (Reserve) (SAS(R)) unlike the regular SAS Regiment it accepts members of the general population without prior military service.

History

The unit was founded in 1959, as an additional regiment of the Territorial Army, and was created from the former Reserve Reconnaissance Unit, itself descended from the body of the organisation known as Military Intelligence 9. The regiment's first commander was H. S. Gillies, at the time a lieutenant colonel. Anthony Hunter-Choat OBE was the commanding officer of the regiment from 1977 to 1983. Sebastian Morley, at that time a major, was for a period commander of D squadron until his resignation sometime during 2008.

21st century

The reservists were at some time involved directly in the training the Afghan National Police, during the most recent Afghan war, following a review of their unit's operational capability they were withdrawn from front line operations and the task handed over to a "regular" infantry unit. The report found that the TA SAS lacked a clearly defined role, and also stated that the reservists lacked the military capability and skillset to serve alongside the regular special forces

26th Space Aggressor Squadron

The 26th Space Aggressor Squadron (26 SAS) is a unit of the United States Air Force located at Schriever Air Force Base, Colorado. It is part of the 926th Group and is the Reserve Associate of the 527th Space Aggressor Squadron.

The mission of the 26th Space Aggressor Squadron is to replicate enemy threats to space-based and space-enabled systems during tests and training exercises. By using Global Positioning System and satellite communications jamming techniques, it provides Air Force, joint and coalition military personnel with an understanding of how to recognize, mitigate, counter and defeat these threats.

The 26 SAS serves to know, teach and replicate a wide array of terrestrial and space threats to the U.S. military's space enablers. The squadron trains the modern warfighter to operate in an environment where critical systems like GPS and SATCOM are interfered with or denied—preparing them for the current and future fights, and guaranteeing U.S. battlefield dominance well into the 21st century.
