General Custer

 is a cut achievement/trophy in Fallout: New Vegas which is awarded for leading all your companions to their deaths. As companions only become "unconscious" in regular play mode, this achievement would only be obtainable on Hardcore mode.

Behind the Scenes
This is a reference to General Custer, who led men to their deaths in the Battle of Little Big Horn against a combined Lakota-Northern Cheyenne and Arapaho force, on June 25, 1876.
