The leading superteam of defenders of the Galactic Union, an interstellar republic of which 24th century Earth is a member. The team that is called in to deal with threats or problems too big for the regular forces of law, order and security to handle. The team that is usually first into the unknown and possibly dangerous corners of the galaxy. The team that exemplifies the best, brightest and bravest the GU has to offer. The team called-the Vanguard.
