Remember way back in the first year of this game, everyone was trying to figure out the importance of the Gold Ranger Elites in the campaign? For some reason they were called BOBs and there was like hundreds of theories surrounding their importance. I don’t remember any details or anything but I remember being interested in it and I was just wondering if anything important was ever found about these guys.
I don’t think there was anything important about the special elites. The nickname BOB can from Bungies Marathon game. It is an acronym for Born On Board. I can tell you that there were in the end 47 BOBs on reach that appeared throughout the game and some would only appear when you played on legendary mode.
When you killed one they appeared in the post game report as kill on a light vehicle and it was a special medal only visible on Bungie.net.
Finding them was sometimes a real challenge but other than that they didn’t do anything or give you anything special in the game.
I heard they drop Plasma Repeaters. That’s about it.
I used to think that’s how people got the Legendary Flames but I guess it turned out to be a medal. I think they are non canon, so they were probably an easter egg on Reach.
