The E.I.N is an intelligence agency based in Germany that serves all of Western Europe and is particularly prominent in Germany, Italy, Britain, Greece, Romania, Russia, Poland, Bulgaria, France and Spain with assistance from Denmark, Austria, Switzerland, Belgium, The Netherlands, Luxembourg and Liechtenstein, there is also another branch in West Turkey which assists the E.I.N. The organization is led by British-born Graham Johnson and his deputy Noah Young.
In the Cold War II series the E.I.N's agents appear predominantly and are especially from Germany, Italy, Great Britain, Greece, Romania, Russia, Poland, Bulgaria, France and Spain. The agents depicted in the series are largely composed of women while fellow secret agents who aid the E.I.N and are men are from their country's respective intelligence services such as MI5 or MI6 in the UK.
In The Recruits, the E.I.N is shown to be more diverse in membership involving Danish and Dutch officials and its recruits are even more diverse as shown by the events of this series. There are hundreds of Danish girls and Dutch girls training with the E.I.N and more girls join them with the arrival of several Scandinavian girls to train for the organization.
In it's feature Agents of Tomorrow the E.I.N's agents are shown to be a lot more uniform in diversity and features German and English agents more prominently.
In addition of the agents only four are shown as daughters of former E.I.N agents and the rest are not affiliated with it, the agents are also shown to be a lot smaller as the number of individual agents is 16. Therefore the total number of agents in Agents of Tomorrow is 32 (16 Germans and 16 English)
The main leaders are a main leader, his/her deputy and a quartermaster as before but the main leader is accompanied by a male and a female supervisor who also act as their advisers and after this it is more segregated. For male recruits they receive training for weapons by an older male E.I.N agent and reconnaissance by another who is generally younger and the same goes for female recruits.
Senior members in the organization's headquarters in Berlin as well as in the United Kingdom tend to be mostly British or of dual nationalities mostly British-Asian because of the fact the E.I.N has many allies in Africa. Each branch has senior members which are the main nationalities for example: The E.I.N's English branch has senior members which are English and British-Asian whilst it's German branch has German and British members. Whilst in countries like France and Spain there are senior and individual members who are French or Spanish.
Women in the E.I.N particularly those that are agents are recognized in the same way that the Vixens of the National Protection Process are recognized: Agents in the E.I.N are recognized by leather catsuits, often with utility belts.
On their feet, they wear the same colored boots like fashion boots which are typically knee length and have low heels.
The suits are typically dark colours but can also be dark blue, red or dark green. Agents in West Turkey however are far more subtle and recognizable through traditional Islamic attire, unlike some senior members of the E.I.N however like Zarah Langhani, Asma Ghazali and Leila Ebrahimi who are Asian but do not wear headscarfs, West Turkish agents wear the full package including abayas and head scarves.
While granted, other Muslim women in other literature wear the full package as well, Turkish characters from the Cold War II series whether heroic or villainous, are the only Turkish characters to wear the full package because the Lionesses of Turkey from Defenders of Earth do not wear Islamic attire thanks to them being criminals. They do however, wear Islamic attire over their uniforms as disguises.
Other girls in the E.I.N meanwhile often wear more fashionable clothing or plain clothing such as leggings or in some cases summer dresses. Even when they are not training, Chelsea boots are a common piece of footwear among recruits when they are not training. And even when they are, the catsuits are not often worn by younger recruits such as Elisabet's right hand girl Arnbjorg Berthelsen who are the ages of 17. The suits are traditionally often worn by girls from the ages of 18 and 19.
The two additional protagonists in the series, Aardina De Winter and Aleksia Jessen also sometimes wear catsuits when helping the three girls and in the case of Aardina, she could be considered to be braver because she mixes her uniform up and instead often wears a black latex catsuit and red knee length boots.
In Agents of Tomorrow, the bodysuits and the catsuits remain in fashion and while some agents are fairly plain, other agents accessorize which is both prominent on the field and off the field.
This is particularly prominent for Helga's daughter Greta Blankenburg who wears a black catsuit but adds a corset while another agent Denise Benedict wears a crimson catsuit with crimson boots on the field but off the field, she wears the catsuit and adds tights and high heels.
And again, just as Aardina De Winter does in The Recruits some of the new agents become more fashionable by mixing up their suits and their boots, for example; One agent may wear a silver catsuit but wear black boots. All of the suits worn by E.I.N agents are also worn by the Eastern Vixens, women in the terrorist organization PHANTOM and various other organizations composed entirely of women such as the Women of the Night and the Force of Amazon; the suit worn by Denise is also worn by the Bulgarian criminal Stanimira Zhelyaskova.
Members of the cabinet however wear more business style clothing except for Faizan Anwar who wears military fatigue. (though he is not counted because he is an external interviewer) Most officials are also as affluent as the heads of the E.I.N as most of them live in former country houses in the United Kingdom, particularly those who are Southern such as Gemma Farnworth who is Hertfordshirean (lives in Hertfordshire) or Celtic such as Goffraid Halligan who is Irish or Seran Crowther who is Welsh.
Many of the E.I.N's agents are also well regarded for many of their vehicles that are used. Whilst the agents own impressive cars Johnson/Gathercole and other senior personnel own a lot more impressive ones, in the case of Johnson and later Gathercole both own a Maybach whilst some senior personnel accompany him in Volkswagen Transporters and members of the cabinet often have their own cars.
Most of these cars tend to be more luxury vehicles and have the ability to take off and land like a normal aircraft. Most have guns in their grills but all have bombs located at the bottom of their chassis. They also tend to fit the agent's nationality for example a German agent will own a Mercedes or a BMW whilst a British agent would own a Bentley or a Rolls Royce.
Many Eastern agents on the other hand, particularly Romanians and Turkish agents, tend to use more Eastern cars that are also used by The Company whereas Spanish agents tend to use Italian cars which are largely Ferrari's; of the Spanish agents, only two agents own a Lamborghini: Sofia Amparo who owns a Murcielago and Bonita Alfronseca who owns an Aventador.
Italian cars, in particularly Maseratis, are also very popular with Greek agents owing to Italy and Greece being Mediterranean countries.
The vehicles feature the traditional features of luxury vehicles but also include run-flat tires, taxi style microphone radios and other features of armored vehicles. Many of the cars may have traditional logos such as a BMW or a Mercedes but they also bear the E.I.N logo which is a red version of the E.U. flag (traditionally yellow stars in a circle on a blue background) with a black cross on a white circle background (representation is in the main image).
