Captain Vince Grant was the commanding officer of many vessels. In early 2044, he took command of the newly upgraded Tokugawa. In July of 2044, Vince was placed in command of the Icarus and the Ark Angel.
During the years before the Zentraedi arrival, he was stationed on Macross Island with his big sister Claudia. On her 1st day he gave her advice to watch out for flirty flyboys. (Robotech: From the Stars: The Program) Later, then the Anti-Unification League had taken over the Armor-1, Roy Fokker had him ready the experimental Valkyrie prototype for launch before it wiped out Macross Island. Although Roy was successful in taking down the Armor-1, it had fired a Reflex warhead at Macross Island. He spent moments with Claudia waiting to see if they would survive as the blast radius would be so large that evacuating would not be possible. In the end, Roy took down the Warhead and saved the Island. (Robotech: From the Stars: The Gathering Storm, Commitment)

After the REF returned to Earth to assault the Invid headquarters at The Reflex Point, he became worried due the fact that the SDF-3 was taking too long to come to Moon Base ALUCE. Moments later, the base received a transmission of Rick inside of the SDF-3 expressing his doubts with the Neutron-S Missiles. An accident occurred and the transmission was loss.

Behind the scenes
Despite having been on board the SDF-3 in 2022, having a son born in 2013, and having been in active service in the early 2000s, a scene in Robotech: The Shadow Chronicles (which takes place in 2044) lists his age as 36. The first Robotech II handbook lists his age as 25, which would have made him six during Robotech: From the Stars and 16 at the birth of his son.
Meanwhile, Robotech: The Art of the Shadow Chronicles lists his age as 54.
