For the matching commander of a particular ship, see the card page of that ship or the card page of that personnel.
Star Trek CCG 1st Edition[]
A personnel is the matching commander for a ship if either the ship lore or the personnel lore states that the personnel is or was the commander or captain of the ship. (Also, a few personnel, such as Rinnak Pire and Regent Worf, have special game text that allows them to act as, or assign another personnel as, the matching commander of a ship.)
Star Trek CCG 2nd Edition[]
Some personnel have the keyword "Commander:". After the colon's the name of the matching ship is printed.
