They serve as reinforcements for the Security Department. Nine Tailed Fox - Nine Tailed Fox (a division of the Mobile Task Force, commonly known as MTFs or NTFs) are able to join in the middle of a round by boarding the helicopter in the lobby.

Security Department Officers belong to the SCP Foundation team. An SD's priority is to help Researchers escape while eliminating other threats.

They have one of the biggest advantages, because they have access to powerful weapons (such as a gulf war P90, an Aug, or an Ithaca 37) and a Level 5 Keycard. Security Department - Security Department Officers (commonly known as SD) share a team with Researchers. Researchers belong to the SCP Foundation team. The Security Department can also help researchers escape the facility. Unlike Class D's, they can buy a Level 3 Keycard to help them during the round. They spawn with a Level 2 Keycard, which opens several doors that enable them to get more items and hopefully escape. Researcher - Researchers start with a slight advantage. Class D's generally must work together to escape threats, find items, and make their way to Gate A or Gate B. They also do not have the ability to get any items before the round starts. There are currently 8 round types, with most of them changing the way teams are placed and two of them changing the map entirely.Д¬lass D - Class D Personnel are at the greatest disadvantage, because almost every team (except for Chaos Insurgency) is their enemy. For example, Class Ds and Researchers must escape while avoiding threats. When a new game round starts, all players are randomly placed onto teams.
