Six weeks into her commission during an encounter with a faction of non-collective Borg led by Lore, Ensign Taitt manned the tactical station under the command of (Doctor) Commander Beverly Crusher. She hesitantly held her post, and under orders, established a frequency shift firing pattern on a Borg starship.
When Commander Crusher took the Enterprise, protected by metaphasic shielding into a local star, it was Taitt's observations and expertise in Solar Dynamics that allowed her to use ship's phasers to trigger a solar flare - destroying the Borg. A move Commander Crusher christened the "Taitt Maneuver". (TNG episode: "Descent", novelization: Descent)
