Class D

Class-D (Class Disposable) are inmates from around the world, promised that all of their crimes would be pardoned if they finish a period of duty in one of the many SCP sites. They are often used for tests on the SCPs, hence the name "Class Disposable".

In the game Site-19, the primary objective is to escape the facility through Gate A or Gate B. If they do this, they become a member of the Chaos Insurgency. While you can escape, you can also participate in tests on the SCP objects.

CD (Class-D) do not have to "follow" any item use laws, but be aware that you can be terminated if you have any item, excluding the mop.

Strategies for escaping
You can find L-3 cards in the SCP-173 storage room along with the researcher spawn area. With these, you can either upgrade them to L-4 cards to escape, or you can go to the armories and get guns to defend yourself. If you want to be more discreet about it, you can pick up some sort of item, go to SCP-1162 (Hole in the wall) and interact with the hole until you get an L-3 card.

If you want to escape during a raid, but SD or MTF are always camping the GB surface, you can go through the GA maitenance tunnels to get to the CI spawn.
