An unofficial group consisting of members of national law enforcement, intelligence and the military. Delta Green itself has no funding but those who run it channel funds, equipment and personnel as needed from whatever agency or military branch they happen to work for. Delta Green specializes in situations where the members feel rivalries among different parts of government would make efficient problem-solving difficult, not to mention keeping things secret. For the most part, this has meant dealing with the paranormal and particularly the Cthulhu Mythos.
Delta Green, sadly is not an intelligence-gathering body; its focus is problem resolution. Those who carry out Delta Green missions rarely learn anything about what they face; they simply go somewhere, do something, and come home. As a result, Delta Green’s organizers aren’t very informed about the Mythos, nor do they want to be. They simply want to screen the rest of the government from getting involved in such peripheral problems.
Delta Dreen’s agents are not full-time; they work in various capacities, for other groups such as the FBI, the NSA, the Army, the IRS, etc. They are “assigned” to a Delta Green mission by their Delta Green-member supervisors, who camouflage their activities as being part of their regular duties. there are no regular meetings, no headquarters, etc; members simply contact each other when their respective agency stumbles on something that Delta Green is better capable of handling. Thus there is no Delta Green database, no files, no letterhead or reports. To gather a full profile of their activities one would have to comb the files of most national government bodies, finding evidence of operations sanctioned hastily and with little apparent result. Scattered thusly, Delta Green is hard to locate; only if such reports were assembled and considered in the aggregate would a clearer picture emerge.
In other words, Delta Green is little more than an ad-hoc assembly of people “in the know”, an old boys network if you will. with no central command whatsoever. When one member happens upon something he or she contacts a few others who might be of help and they deal with the situation. Any knowledge gained is effectively lost due to the lack of any real structure.
