I have to agre with Legion. Space marines would dominate a Spartan or the N7 classes. Like my post above, you need to take account the magical properties of Space Marine armour and how modified their wearers are. There is no way that there would be a victor outside of a Space Marine. Now, I don't read Ultramarine lore, or do I play them, but I do continuously play Space Wolves, and I have read all their lore, and if anything Ultra Marines are more disciplined if less brutal so my results stands, Space Marines greater than all
