The Ophiuchi Association Defense Command (OADC) is the navy of the Ophiuchi. Designed to work in joint TFN-OADC battlegroups, the ships of the OADC had Datalink that could interface with the TFN ships, and their strikegroups were regarded as pearls without price, as Ophiuchi pilots were, one-on-one, the best fighter jocks in known space.
