This structure has a single set of large, thick, steel doors through which both vehicles and personnel may enter and leave. Heavy security fences and a paved perimeter are present around the structure's perimeter. Ideas associated with the site's function are 'SDI' and 'command and control,' 'antennas,' and 'telemetry.' (See accompanying detailed perceptual sketches, also). Source 018: Describes a cluster of structures, including a tall structure which appears to be an antenna that radiates a very large amount of energy. Two other structures are connected via underground 'pipes' to this antenna. Energy, in some form, is sent from one structure through a pipe to the antenna, and 'information' flows from the antenna to the other structure. Ideas associated with the site center around 'command and control' and 'continuous communications.' (See accompanying site layout sketches, also). Source 095: Describes an open area with several structures present. One structure is massive and high, like a huge 'blockhouse' and, connected with it, is the idea of 'roll out' of very large assemblies. The assemblies themselves are associated with troops wearing black uniforms. There are several long, SG1A buried duits)or ,cables' in the area, one of which is connecte a--structure containing 'condensed, contained energy' (like a "tokamak"). Another structure has a geometry similar to the Ideas associated with this site are 'concealment and secreo~r.' ILLEGIB SG1J e 2000/08/08 : CIA-RDP96-00789ROO0400250004-7
