Personnel

"Class D personnel are expendable personnel used to handle extremely hazardous anomalies and are not allowed to come into contact with Class A or Class B personnel. Class D personnel are typically drawn worldwide from the ranks of prison inmates convicted of violent crimes, especially those on death row."

Scientific Department

"Efficient scientific work is the cornerstone of the Foundation's existence and operation. The Scientific department is responsible for studying all contained and new SCP objects, developing countermeasures for containment breach events and designing various devices and medicinal products to be produced by the Manufacturing Department. Scientific Department employees are recruited from among the best and most promising scientists in various fields."

Security Department

"This department is responsible for providing security and protection for all Foundation facilities and objects, regardless of their priority. SD employees are trained to counteract containment breach events, intrusions, sabotage, natural disasters, and other emergencies. Newcomers to this service usually undergo general training before being assigned to an object or site. Special training for working with a given object is performed on-site after assignment."

Combatant Roles

Combatant roles are roles that require XP to unlock. They all spawn with weapons and can engage in combat. Combatant roles are part of Foundation staff and are hostile to Chaos Insurgency and guilty Class-D. Combatant roles include:

Mobile Task Force

"The Foundation's line of work requires a large number of highly specialized professionals. This is usually related to anomalies that require much effort and an unorthodox approach for containment. To address this, Mobile Task Forces are formed. MTFs are teams of varying size that specialize in specific roles or respond to specific situations. Every group has a name consisting of a Greek letter and a number; clarification prefixes and/or call signs may be employed in some cases."

Intelligence Agency

"The Intelligence Agency is tasked with searching, tracking, and capturing uncontained SCP objects and gathering intelligence on hostile groups of interest. Undercover IA cells exist in every major populated area and disguised as civilian objects and institutions. Intelligence agents are usually recruited from various defense and law enforcement agencies and special services of the world."

Internal Security Department

"ISD is a concealed "foundation within the Foundation", a secret police force responsible for filtering traitors as well as operational and information security risks among the Foundation's ranks. The department is strictly hierarchical, adhering to stringently defined multi-stage investigative protocol. Potential ISD agents must have a perfect service record and a length of Foundation service of more than a year. Usually, every ISD agent keeps his "official" position in order to provide his command a first-hand account of everything happening in a given department. The very existence of ISD is usually presented as a myth. The "official" responsibility of ISD is investigation and interrogation of captured GOI agents, although that part of ISD officially belongs to Security Department for the purpose of secrecy."

Rapid Response Team

The Rapid Response Team is non-canon and does not exist in the official lore. However, the tutorial explains that in SCP: Roleplay the Rapid Response Team is composed of combat veterans who are mainly armed to protect against massive Class-D riots and the Chaos Insurgency. They are experienced in the Nuclear Warhead Procedure and are tasked with escorting personnel to safety.
