Jeff McAlister was a Starfleet cadet in the 24th century.
McAlister majored in command. By the age of 20.4 standard years, he had been assigned to Red Squad, something that he considered an honor and the epitome of that for which Starfleet stood. He also made it clear that he wished to break Tryla Scott's record of the youngest captain in Starfleet history. (Last Unicorn RPG module: Starfleet Academy Handbook)
