chunk: Reliant. Though Khan believes his foe stranded on Regula I, Kirk and Spock use a coded message to arrange a rendezvous. Kirk directs the Enterprise into the nearby Mutara Nebula; static discharges inside the nebula render shields useless and compromise targeting systems, making the Enterprise and the Reliant evenly matched. Spock notes however that Khan's tactics are two-dimensional, indicating inexperience in space combat, which Kirk then exploits to critically disable the Reliant.
