[@Sleeth] you realise Spartan IV's still have to go through the enhancements and stuff to wear their armour right? They still have that process much like the II's had. And in all fairness, they are actually a pretty close match. Spartan II's are, and for the foreseeable future will be, tougher, faster and stronger, but Spartan IV's can stand up to them (not single handed my maybe, but Eryx isn't really making friends right now..). II's aren't really indestructible, that's just ONI propoganda... :p
