Commander Valentine(†) was the squad leader of Sergeant Rita Torres first squad.
During Valentine's first assignment with Torres in his squad, he made a critical error allowing his squad to fall into a Pirate trap led by Captain Jubail. During the fight, Valentine had saved Torres from getting shot down.
The entire squad was wiped out and Valentine was shot down and killed. Eventually, Torres was also shot down by Jubail and thought to be left for dead.
Even though it was very many years later, Torres tried to get revenge and assaulted Jubail in the first days of the Exofleet - Pirate Clans Alliance. Though she was court-martialed, she was eventually bailed out by J.T. Marsh.
