Intended to be used as something comparable to a small auditorium, the large ready room is capable of seating a full brigade, or five-thousand personnel. These ready rooms have auditorium style seating, complex audio-visual presentation equipment, and a central platform in which a presenter is able to see everyone in the ready-room, and vice-versa. Often, these rooms are limited to extremely large ships such as carriers and battleships, and in large installations. These rooms can be used for simple mission briefings, or even other forms of presentations.
