The Neller Center houses a 300-person auditorium, gaming classrooms, game arenas, breakout rooms and conference rooms, all helping personnel visualize threats, simulate operating environments and gain advantages over adversaries. The mix of spaces — larger arenas for replicating remote operations units and smaller rooms for independent, secure assessments — allows monitoring and recording by controllers, generating authentic learning opportunities. Specific and sophisticated A/V design approaches facilitate the users’ unique needs.
