Im pretty sure that there we 20 ODPs defending Reach edit: Not nesscessarily Earth, as there were ODPs over Reach--UNSC AI 12:02, 30 May 2007 (UTC)
Your correct page 283 in Fall of Reach states that "there were 20 super MAC guns in orbit" I made the proper change
something
after reach you'd think they would reaseach a way to put generators on the guns,so they're more of a threat and are "easier" to defend,and i'm guessing the Earth is a WHOLE lot bigger then Reach cause if 20 was in orbit around Reach and 300 around Earth Voy101
