In November 1977 the Special Forces Operational Detachment Delta - Delta Force -, the USA's specialist anti-terrorist and hostage rescue unit came into being. The driving force behind Delta Force was Colonel Charles Beckwith, a Special Forces officer who had been extremely impressed by Britain's SAS during an exchange tour in the early 1960s. For several years he badgered the Pentagon into setting up a similar unit in the US Army. Selection for the new unit was very much SAS style, with hard physical, mental and psychological challenges weeding out nine out of 10 applicants. Once selected, the successful candidate is sent on a five month 'Operators' course, where he is introduced to the many and varied skills; than an anti-terrorist commando is expected to master. These include assault tactics, hostage management, communications, observation using the latest high-tech equipment, climbing, small boat work and parachuting.
Since the majority of Delta Force candidates are from Special Forces or Ranger units they already possess many of these skills, but even so they learn a lot before moving to their operational troop. Delta Force is organised into operational squadrons, each squadron is broken down further into troops. Marksmanship is a prime requirement in Delta Force and Force members train up to four hours a day, five days a week. Such intensive training leads to very high shooting standards: Delta snipers are expected to make nine first-round hits out of 10 at 1,000 yards, and score every time at 600 yards. Like other elite counter-terrorist units, Delta Force has built its own 'House of Horrors' which simulates various kinds of combat situations, from hostage taking to aircraft hijacks. Hijacks are a favourite terrorist activity, so Delta Force has practised assaults on airliners, and regularly runs training exercises at New York's Kennedy Airport and at other large international gateways. Delta receives terrorist intelligence from US Government organisations such as the CIA, the Defense Intelligence Agency, the FBI, and from contacts with other anti-terrorist units around the world. Its members also make exchanges with the British SAS, Germany's GSG-9, the French GIGN and other similar units.
Delta Force was set up in less than a year, becoming operational in the middle of 1978. Just over a year later, the Force was alerted to a possible rescue mission as the US Embassy in Teheran was seized and the embassy staff held hostage. This was far from the mission they had trained for: penetrate hundreds of miles into hostile territory, making an assault in the middle of a major city and then getting clear with 100 or more freed hostages.
Months of intensive training went into 'Operation Eagle Claw' as the rescue mission was called, planned for the 25th of April. It was to involve Delta Force, Special Forces units from Germany, US Marine Corps helicopter Pilots, US Navy helicopters and ships and US Air Force air support. The mission was a disaster, although through no real fault Of the men who took part. Command and control of the many disparate parts of the rescue operation were shambolic. The big MH-53 helicopters could not cope with the desert sand, and there were not enough of them. After three had broken down the mission had to be aborted. To add to the whole affair, a collision at the 'Desert One' airstrip deep inside Iran killed eight men and destroyed a C-130 and a helicopter.

Detecting set L4A1 was the British Army designation for the Plessey P6/2 Metal detector range.
The P6/2 equipment consisted of a waterproof electronic unit and a set of operator-interchangeable waterproof probes. The operating mode was pulsed induction. Target detection was indicated audibly by a loudspeaker or plug-in earphone(s). Switched sensitivity and response times were provided. Power was supplied from internal batteries or an external source via an adaptor. An in-built battery check was provided. The function switch, loudspeaker, probe and earphone sockets wee located on a control panel at-the top of the electronic unit. The electronic unit was carried in a slung webbing haversack for manpack operation.
Four types of probe were provided as standard, each for a specific purpose. A connection cable terminated in a quick release plug is integral with each probe.
- P6A/2 was a tubular ferrite probe suitable for searches in bushes, streams and rugged urban and rural environments.
- P6E/2 Open Loop Probe was a lightweight probe, for ground search applications.
- P6F/2 was a short robust probe for general searches in restricted environments.
- P6G/2 was a light easy-to-use probe designed for the searching of persons.
Plessey could also supply special probes that could be designed for particular applications e.g. the P6C/2 sledge probe.
The P6/2 equipment was designed to perform over the frequency range 50 to 500MHz. When fitted with a P6A/2 or P6F/2 probe and an MDA7/2 earpiece the P6/2 was capable of operating within four metres of a 1W, handheld radio transmitter or within six metres of a vehicle-mounted 10W radio transmitter without malfunctioning, blocking, or causing interference to the receiver in the radio station.
Typical detection range for the P6E/2 Probe was approximately 220mm with a 2p coin or 250mm2 copper, 18 G and approximately 400mm with a pistol

A detonator is a contrivance containing a very sensitive explosive, used to fire a larger charge of a less sensitive and more manageable explosive. Detonators commonly contain mercury fulminate, lead azide and tetranitroaniline. Certain chemical compounds have been commonly used as detonators. These compounds on being exposed to heat or suddenly struck, explode with a loud report, owing to one or more of the constituent parts suddenly assuming the gaseous state. The chloride and iodide of nitrogen are very powerful detonating substances. The compounds of ammonia with silver and gold, fulminate of silver and of mercury, detonate by slight friction, by means of heat, electricity, or sulphuric acid.

The Regiment was founded in 1958 from the amalgamation of the former Devonshire and former Dorset Regiments. The Regiment traces its history back to the forming of the 11th Regiment of Foot (known as the Bloody Eleventh), later the Devonshire Regiment, in 1685, and the 39th and 54th Regiments of Foot, later to become the Dorset Regiment. From its first Battle Honour of Dettingen in 1743 the Regiment has seen action in all the main campaigns, and many smaller ones, fought by the British Army over the past 300 years. A selection of its 141 Battle Honours give an idea of these campaigns all over the world - Plassey, Salamanca, Pyrenees, Sebastopol, Afghanistan, South Africa, Mons, Ypres, Loos, Somme, Gallipoli, Mesopotamia, Normandy, Arnhem, Rhine, Sicily, Italy, Mandalay, Burma. In the Great War the Regiment raised 35 battalions and 20 in the Second World War who fought in all the major areas of conflict.
Today its 1st Battalion, a regular army unit, is stationed in Paderborn in Germany, and its 4th Battalion, a territorial army unit, is based in barracks in the Regiment's two counties. Since 1945 the regular battalions have seen active service in Malaya, Kenya, Cyprus, Guiana, Belize, Northern Ireland and in 1995 served with United Nations forces in Bosnia. The present regular battalion is an armoured infantry one equipped with Warrior armoured personnel carriers in the 1st (UK) Armoured Division part of NATO' s Allied Rapid Reaction Force. The Regiment has strong links with its home counties of Devon and Dorset which is its main area of recruitment. The majority of soldiers in the Regiment come from the two counties and, besides having the Freedom of 12 cities and towns, the Regiment maintains close affiliations with many organisations in the counties, and with the Cadet Forces and also runs a flourishing association to keep all who have served in the Regiment in touch with each other.

Dimethyl sulphate is a toxic gas that was used in the Great War by the Germans (who called it D-Stoff) and the French (who called it Rationite). It is a powerful irritant in low concentrations, and is fatal in higher concentrations and after long exposure, and has a peculiar caustic action on the skin. It decomposes readily in the presence of moisture, even damp air, and so was little used.

Diphenylchlorarsine is a toxic gas that was used by the Germans (who called it Clark 1) in the Great War. Inhaling the gas causes nausea, vomiting, headaches, and chest pains but it is rarely lethal and then only in extremely high concentrations rarely achieved in field conditions. It was introduced simultaneously with mustard gas as the agent to be used on offensive operations, since mustard was too persistent to be used against areas toward which German troops were advancing. It was specifically aimed at penetrating Allied gas masks, by distributing the substance as a fine dust which could not be neutralized by the chemicals or stopped by the coarse filters in the masks. However, a technical error in the design of the shells used to fire the gas meant the dust was too coarse to penetrate gas masks.
