A '''covert operation''' or '''undercover operation''' is a military or police operation involving a [[covert agent]] or troops acting under an assumed [[cover (intelligence gathering)|cover]] to conceal the identity of the party responsible.<ref>{{Cite book|last=Carson|first=Austin|url=https://www.jstor.org/stable/j.ctv346p45|title=Secret Wars: Covert Conflict in International Politics|date=2018|volume=157 |publisher=Princeton University Press|pages=5–6|doi=10.2307/j.ctv346p45 |jstor=j.ctv346p45|isbn=978-0-691-20412-3 }}</ref>

==US law==
Under US law, the [[Central Intelligence Agency]] (CIA) must lead covert operations unless the president finds that another agency should do so and informs Congress.{{sfn|Daugherty|2004|p=25}} The CIA's authority to conduct covert action comes from the [[National Security Act of 1947]].{{sfn|Daugherty|2004}} President [[Ronald Reagan]] issued [[Executive Order 12333]] titled ''United States Intelligence Activities'' in 1984. This order defined covert action as "special activities", both political and military, that the US Government could legally deny. The CIA was also designated as the sole authority under the 1991 [[Intelligence Authorization Act]] and in [[Title 50 of the United States Code]] Section 413(e).{{sfn|Daugherty|2004}}<ref>''All Necessary Means: Employing CIA operatives in a Warfighting Role Alongside Special Operations Forces'', Colonel Kathryn Stone, Professor Anthony R. Williams (Project Advisor), United States Army War College (USAWC), 7 April 2003, page 7</ref> The CIA must have a "Presidential Finding" issued by the President in order to conduct these activities under the [[Hughes-Ryan Amendment|Hughes-Ryan amendment]] to the 1991 Intelligence Authorization Act.{{sfn|Daugherty|2004|p=25}} These findings are then monitored by the oversight committees in both the US Senate and House of Representatives.{{sfn|Daugherty|2004|p=28}} As a result of this framework, the CIA "receives more oversight from the Congress than any other agency in the federal government", according to one author.{{sfn|Daugherty|2004|p=29}} The [[Special Activities Division]] (SAD) is a division of the CIA's [[Directorate of Operations (CIA)|Directorate of Operations]], responsible for Covert Action and "Special Activities". These special activities include covert political influence and paramilitary operations.

===Impact===
According to a 2018 study by University of Chicago political scientist Austin Carson, covert operations may have the beneficial effect of preventing escalation of disputes into full-blown wars.<ref name=":0">{{Cite book|last=Carson|first=Austin|url=https://www.jstor.org/stable/j.ctv346p45|title=Secret Wars: Covert Conflict in International Politics|date=2018|volume=157 |publisher=Princeton University Press|doi=10.2307/j.ctv346p45 |jstor=j.ctv346p45|isbn=978-0-691-20412-3 }}</ref> He argues that keeping military operations secret can limit escalation dynamics, as well as insulate leaders from domestic pressures while simultaneously allowing them communicating their interest to the adversary in keeping a war contained.<ref name=":0" /> He finds that covert operations are frequently detected by other major powers.<ref name=":0" />

A 2024 study found that state denials of covert actions, even when the covert actions were obvious, could have a de-escalatory effect (compared to making the covert action public).<ref>{{Cite journal |last1=Bloch |first1=Chase |last2=McManus |first2=Roseanne W. |date=2024 |title=Denying the Obvious: Why Do Nominally Covert Actions Avoid Escalation? |journal=International Organization |volume=78 |issue=3 |pages=600–624 |language=en |doi=10.1017/S0020818324000183 |issn=0020-8183|doi-access=free }}</ref>

==Domestic settings==
To go "'''undercover'''" (that is, to go on an '''undercover operation''') is to avoid detection by the object of one's observation, and especially to [[deception|disguise]] one's own identity (or use an [[assumed identity]]) for the purposes of gaining the trust of an individual or organization in order to learn or confirm confidential information, or to gain the trust of targeted individuals to gather information or [[Evidence (law)|evidence]]. Undercover operations are traditionally employed by [[law enforcement agencies]] and [[private investigators]]; those in such roles are commonly referred to as undercover agents.

==Black operations==

A black operation or "black ops" is a covert or [[clandestine operation]] by a [[government agency]], a [[military unit]] or a [[Paramilitary|paramilitary organization]] in which the operation itself is at least partially hidden from the organization or government's own scrutiny.<ref name="Smith">{{cite book|last=Smith|first=W.

==History==
Law enforcement has carried out undercover work in a variety of ways throughout the course of history, but [[Eugène François Vidocq]] (1775–1857) developed the first organized (though informal) undercover program in France in the early 19th century, from the late [[First French Empire|First Empire]] through most of the [[Bourbon Restoration in France|Bourbon Restoration]] period of 1814 to 1830. At the end of 1811 Vidocq set up an informal plainclothes unit, the ''[[Brigade]] de la [[Sûreté]]'' ("Security Brigade"), which was later converted to a security police unit under the [[Prefecture of Police]]. The Sûreté initially had eight, then twelve, and, in 1823, twenty employees. One year later, it expanded again, to 28 secret agents. In addition, there were eight people who worked secretly for the Sûreté, but instead of a salary, they received licences for gambling halls. A major portion of Vidocq's subordinates comprised ex-criminals like himself.<ref>{{cite book|last= Hodgetts|first= Edward A.|title= Vidocq. A Master of Crime|year= 1928|publisher= Selwyn & Blount|location= London}}</ref>

Vidocq personally trained his agents, for example, in selecting the correct disguise based on the kind of job. He himself went out hunting for criminals too. His memoirs are full of stories about how he outsmarted crooks by pretending to be a beggar or an old [[cuckold]]. At one point, he even simulated his own death.<ref>{{citation|surname1= Morton, James|title= The First Detective: The Life and Revolutionary Times of Vidocq |publisher= Ebury Press|isbn= 978-0-09-190337-4|language= de|year= 2004 }}</ref>

In England, the first modern [[police]] force was established in 1829 by Sir [[Robert Peel]] as the [[Metropolitan Police]] of London. From the start, the force occasionally employed plainclothes undercover detectives, but there was much public anxiety that its powers were being used for the purpose of political repression. In part due to these concerns, the 1845 official ''Police Orders'' required all undercover operations to be specifically authorized by the [[superintendent (police)|superintendent]]. It was only in 1869 that Police commissioner [[Edmund Henderson]] established a formal plainclothes detective division.<ref>{{cite book|url= https://books.google.com/books?id=wIf5w6BJOmQC|title= Historical Dictionary of Law Enforcement|author= Mitchel P. Roth, James Stuart Olson|year= 2001|publisher= Greenwood Publishing Group|page= 271|isbn= 978-0-313-30560-3}}</ref>

[[File:Special Irish Branch.jpg|thumb|left|[[Special Branch]] detectives on an undercover operation at the [[London Docks]], 1911]]
The first [[Special Branch]] of police was the [[Special Irish Branch]], formed as a section of the [[Criminal Investigation Department]] of the [[Metropolitan Police|MPS]] in London in 1883, initially to combat the bombing campaign that the [[Irish Republican Brotherhood]] had begun a few years earlier. This pioneering branch became the first to receive training in [[counter-terrorism]] techniques.

Its name was changed to [[Special Branch (Metropolitan Police)|Special Branch]] as it had its remit gradually expanded to incorporate a general role in counter terrorism, combating foreign subversion and infiltrating [[organized crime]]. [[Law enforcement agency|Law enforcement agencies]] elsewhere established similar Branches.<ref>{{cite book|url=https://books.google.com/books?id=1fqAZzIDlgYC|title=Dictionary of Policing|author1=Tim Newburn|author1-link = Tim Newburn|author2=Peter Neyroud|author2-link = Peter Neyroud|year=2013|publisher=Routledge|page=262|isbn=978-1-134-01155-1}}</ref>

In the United States, a similar route was taken when the [[New York City Police Department]] under [[New York City Police Commissioner|police commissioner]] [[William McAdoo (New Jersey)|William McAdoo]] established the Italian Squad in 1906 to combat rampant crime and intimidation in the poor Italian neighborhoods.<ref>{{cite book|url= https://books.google.com/books?id=OB0wOgBbHHkC|title= Italian Americans in Law Enforcement|author= Anne T.

==Participation in criminal activities==
Undercover agents may engage in criminal activities as part of their investigation. Joh defined the term ''authorized criminality'' to describe this phenomenon, which she restricts primarily to undercover law enforcement officers, excluding [[informant|confidential informants]].{{sfn|Joh|2009|p=157}} These criminal activities are primarily used to "provide opportunities for the suspect to engage in the target crime" and to maintain or bolster their cover identity. However, these crimes must be necessary to advance the investigation otherwise they may be prosecutable like any other crime.{{sfn|Joh|2009|p=165}} The FBI requires that such activities must be sanctioned and necessary for the investigation; they also stipulate that agents may not instigate criminal activity (to avoid entrapment) or participate in violence except for self-defense or the defense of others.<ref>{{Bluebook journal | last=Op. Atty' Gen. | title=The Attorney General’S Guidelines on Federal Bureau of Investigation Undercover Operations | pin=12 | url=https://www.justice.gov/sites/default/files/ag/legacy/2013/09/24/undercover-fbi-operations.pdf | year=2002}}</ref> Most other legislation surrounding authorized criminality is not uniform and is a patchwork of federal and state laws.{{sfn|Joh|2009|p=168}}

==Risks==
There are two principal problems that can affect agents working in undercover roles. The first is the maintenance of identity and the second is the reintegration back into normal duty.

Living a double life in a new environment presents many problems.  Undercover work is one of the most stressful jobs a special agent can undertake.<ref>Girodo, M. (1991). Symptomatic reactions to undercover work. The [[Journal of Nervous and Mental Disease]], 179 (10), 626–630.</ref> The largest cause of stress identified is the separation of an agent from friends, family and his normal environment. This simple isolation can lead to depression and anxiety.  There is no data on the divorce rates of agents, but strain on relationships does occur.  This can be a result of a need for secrecy and an inability to share work problems, and the unpredictable work schedule, personality and lifestyle changes and the length of separation can all result in problems for relationships.<ref name="Marx, G. 1988">Marx, G. (1988). Undercover: Police Surveillance in America. Berkeley: University of California Press</ref>

[[stress (biology)|Stress]] can also result from an apparent lack of direction of the investigation or not knowing when it will end.  The amount of elaborate planning, risk, and expenditure can pressure an agent to succeed, which can cause considerable stress.<ref name="ReferenceA">Marx, G. (1988). Undercover: Police Surveillance in America. Berkeley: University of California Press.</ref> The stress that an undercover agent faces is considerably different from his counterparts on regular duties, whose main source of stress is the administration and the bureaucracy.<ref>{{cite journal

 |journal= Work & Stress
 }}</ref> As the undercover agents are removed from the bureaucracy, it may result in another problem.  The lack of the usual controls of a uniform, badge, constant supervision, a fixed place of work, or (often) a set assignment could, combined with their continual contact with the [[organized crime]], increase the likelihood for corruption.<ref name="ReferenceA" />

This stress may be instrumental in the development of drug or alcohol abuse in some agents.  They are more prone to the development of an [[Substance dependence|addiction]] as they suffer greater stress than other police, they are isolated, and drugs are often very accessible.<ref name="ReferenceA" /> Police, in general, have very high alcoholism rates compared to most occupational groups, and stress is cited as a likely factor.<ref name="ReferenceA" /> The environment that agents work in often involves a very liberal exposure to the consumption of alcohol,<ref>Girodo, M. (1991). Drug corruptions in undercover agents: Measuring the risks. Behavioural Science and the Law, 9, 361–370.</ref> which in conjunction with the stress and isolation could result in alcoholism.

There can be some guilt associated with going undercover due to betraying those who have come to trust the officer. This can cause anxiety or even, in very rare cases, sympathy with those being targeted.  This is especially true with the infiltration of political groups, as often the agent will share similar characteristics with those they are infiltrating like class, age, ethnicity or religion.  This could even result in the conversion of some agents.<ref name="Marx, G. 1988" />

The lifestyle led by undercover agents is very different compared to other areas in law enforcement, and it can be quite difficult to reintegrate back into normal duties.  Agents work their own hours, they are removed from direct supervisory monitoring, and they can ignore the dress and etiquette rules.<ref>Girodo, M. (1991). Personality, job stress, and mental health in undercover agents. Journal of Social Behaviour and Personality, 6 (7), 375–390.</ref> So resettling back into the normal police role requires the shedding of old habits, language and dress.  After working such free lifestyles, agents may have discipline problems or exhibit neurotic responses.  They may feel uncomfortable, and take a cynical, suspicious or even paranoid world view and feel continually on guard.<ref name="ReferenceA" />
Other risks include capture, death and [[torture]].

==Plainclothes law enforcement==
{{Distinguish|Plain dress}}

Undercover agents should not be confused with [[law enforcement officer]]s who wear '''plainclothes'''{{mdash}}that is, to wear [[Mufti (dress)|civilian clothing]], instead of wearing a [[uniform]], to avoid detection or identification as a law enforcement officer. However, plainclothes police officers typically carry normal police equipment and normal identification. Police detectives are assigned to wear plainclothes by not wearing the uniform typically worn by their peers. Police officers in plainclothes must identify themselves when using their police powers; however, they are not always required to identify themselves on demand and may lie about their status as a police officer in some situations (see [[sting operation]]).

Sometimes, police might drive an unmarked vehicle or a vehicle which looks like a taxi.<ref>{{cite web |url=https://www.youtube.com/watch?v=gs4T19m8a18 |archive-url=https://ghostarchive.org/varchive/youtube/20211221/gs4T19m8a18 |archive-date=2021-12-21 |url-status=live |title=Unmarked Police Cars Responding Compilation: Sirens NYPD Police Taxi, Federal Law Enforcement, FDNY |last=Code3Paris |date=24 July 2017 |via=YouTube}}{{cbignore}}</ref>
