I Had this Suggestion Floating around for sometime as I would like to see this being taken into Consideration, I know that we Already have Surface classes and CI but There should be another group that could have something different in mind that doesn't involve Weaponizing SCPs.
So, I would like to introduce you to-
[C.I.V.] [CENTRAL-INTELLIGENT-VOICES]
A group made out of Civilians, War Veterans and Police that have known about the Foundation by Photography and People within the Facility, not much was spilled as they still have yet to find more about, They found the D-Class to be considered Prisoners of war that have been tortured and kept away from the world, Their mission is to Rescue Class-Ds and bring them to surface ground where they will be given Medical Aid if needed and give them Rations to get back on their feet, they will then ask if the Class-Ds will assist them after sometime has passed, they will not order them to as it goes against Policy for the C.I.V Members. During possible chances, C.I.V. Will Assist CI with Raiding the Foundation in terms of freeing these "Prisoners of War," C.I.V. Soldiers do not know what the SCPs are and will generally be terrified of certain ones or would still consider them Human if they have the shape/outline of a Human being. The Leader of the C.I.V. is Nikolai Tomilinski, A Veteran of the Vietnam War, His Orders are simple, Get in, Get those men and Get the Hell out.
They Come in waves-
Civvies/Rebels- They are simple and Fragile. They come with 100HP and 25 Armor, They will carry SMGs and M1911s, they're the frontline members of the C.I.V.
Heavies- Heavies are the Strong yet Difficult Soldier in the C.I.V. They come with 100HP and 50 Armor, They will carry a BAR that is Strong enough to Open a Pathway to Freedom. They're the Frontline members of the C.I.V.
Hackers/Grunts- They are Fragile but Very Intelligent. They come with 100HP and 50 Armor, They will Carry an MP7 with a Glock-17 and a Keypad Cracker to break through CPs and Gates, They are the backbone of the C.I.V.
Elites/Guards- They are Tough and Quick. They come with 100HP and 50 Armor, They will Carry a Thompson and a M1911, They are the Command members of the C.I.V.
The Leader- He is Tough but Vigilant, His Leading skills, such as Boosting Morale will approve greatly on the battlefield, He comes with 100HP and 50 Armor, He Carries a Thompson with an M1911 by his side, He will also Carry a Keypad Cracker to Break through CPs and Gates, He is the Core of the C.I.V.
