As of 2367, he held the rank of captain, and commanded the USS Chekov. That year, Korsmo's vessel operated alongside the USS Repulse and USS Enterprise-D in a three-way battle between Starfleet, the Borg, and an ancient "planet-killer". His lack of personal experience with the Borg initially prompted him to consider the possibility of working with the Collective to destroy the planet killer, but Riker's decision to attack the Borg and his crew's subsequent refusal to fire on the Enterprise forced Korsmo to recognize that he had gone too far. The Chekov was irreparably damaged in this encounter. (TNGnovel: Vendetta)
