'Strong and Fearless, Defending Roblox Forever...' Remember those words. They may save your life, and millions of others one day. We are SPF, We are Specialized Paramilitary Force! I co-rule an empire called The United Groups of Roblox, along with Bububuzz. It is currently composed of the Specialized Paramilitary Force (SPF), the Elite Combat Unit (ECU), the Fire Bird Clan (FBC) and the Secret Combat Assault Recon (SCAR).
