The Salt Line Ceremony is a Colonial military ceremony, typically taking place before the start of a major battle. A line of table salt is placed on the ground between two rows of soldiers. A passage of scripture is read, and the two rows converge, spreading the salt line with their feet.
Lt. Margaret "Racetrack" Edmondson conducts this ceremony on the battlestar Galactica's hangar deck prior to the rescue mission for the Colonials remaining under Cylon occupation on New Caprica. The extremely emotional ceremony ends with an embrace by Galactica and Pegasus crew members who feel strongly about the fact that they might never see each other again (Exodus, Part I).
