Lieutenant Vicenzo Yacavino was a male human who served as second in command of the Columbia (NX-02) MACO detachment in 2156. Yacavino was aboard the Columbia when it suffered a crippling attack at the hands of the Romulans. Captain Erika Hernandez surveyed the damage to the Columbia while escorted by Yacavino; after determining the damage to be irrepairable, she ordered the ship towards a Class M planet at impulse close to c, a decision some of the MACOs felt strongly against. After the Columbia arrived at the planet later determined to be Erigol, Yacavino was one of the six MACOs that beamed down to survey the surface, and then was joined by the flight officer away team that made contact with the Caeliar, becoming permanent visitors due to their desire for complete isolation from the universe.

When the MACOs decided to rebel and escape their imprisonment on Erigol, Yacavino and Earth Starfleet Lieutenant Kiona Thayer subdued Sidra Valerian. Yacavino then was part of the team to travel to Mantilis and capture the Great Work apparatus, forcing the Caeliar there to reduce the scattering field, allowing Yacavino to contact the Columbia. Yacavino and Major Stephen Foyle beamed up to the vessel with a Caeliar prisoner, Arithon. When Foyle lied about the senior flight officers being dead, Yacavino remained silent. However, Captain Erika Hernandez was able to contact the ship, and ordered the two MACOs placed under arrest. Yacavino perished along with the rest of the crew remaining aboard the Columbia when it entered a subspace tunnel and was buffeted by hyperphasic radiation. (ST - Destiny novel: Gods of Night)
