D-Class Prison

D-class personnel (or Class-D personnel) are the lowest-ranked staff members of the SCP Foundation. Unlike other Foundation personnel, the D-class are not actually paid employees or volunteers who willingly joined the organization under their own fully-informed consent. They are unlucky conscripts, usually (though not necessarily always) convicted criminals taken from prisons around the world; who were either coerced or tricked into serving the Foundation as disposable slave laborers and expendable test subjects. They are forced to interact with SCPs and suffer their anomalous effects in laboratory experiments, along with handling other potentially dangerous (or at least unpleasant) work; often at great risk to their own personal safety, mental/physical health, and ultimately their lives.

As mentioned before, the majority of D-class personnel are prison inmates, especially convicted felons serving long terms for serious violent crimes. Preferably, they have been sentenced to life imprisonment or the death penalty for high offenses like murder. It is not known how exactly the Foundation acquires these prisoners, though it is often implied that they were deceived and lured under false pretenses of freely volunteering at one of the Foundation's secret research facilities, in exchange for receiving parole or commuting their prison sentences. Given that the Foundation has ties to almost every national government in the world, it is also possible that state authorities have made a secret agreement with them to quietly transfer a small percentage of their countries' prison populations over to the Foundation's custody. Though perhaps most disturbingly, one does not actually need to be a wicked murderer to become one of the Foundation's D-class; even putting aside the fact that some countries may lock up prisoners in death row for non-violent offenses, or that innocent people can be wrongly convicted in miscarriages of justice. Under the Foundation policy known as Protocol 12, during times of duress or drastic shortages of potential recruits, then relatively innocent civilians (including non-violent criminals like political prisoners, or refugees and other homeless people) can be unwittingly recruited as D-class personnel. The Foundation may even take young children to use them as sacrifices for anomalies that specifically target victims of their age range, such as SCP-089 or SCP-974.

As D-class personnel are essentially slaves deprived of their human rights, it is not surprising that the Foundation uses harsh methods to keep them in line. D-class who disobey direct orders during an experiment or mission, or otherwise attempt escape or rebellion, may be punished through "termination" (summary execution) by security guards at the discretion of a higher-ranked researcher or site director. D-class may also be terminated if their mind or body has been severely and permanently altered or disabled as a result of exposure to a dangerous anomaly (especially if the effects are contagious).

Typically seen in a windowless facility with a heavily caged in courtyard, D-Class prisoners are subjected to the cruelest of conditions. Guards tend to be vicious and absolute, scientists tend to be uncaring, and even corporations that exist to assist the D-Class, such as rebel forces, have trouble providing relief to those inmates since they’re so heavily trapped by the system they were tricked into.
