[quote][b]Posted by:[/b] Kalriq On top of that, reading the Horus Heresy books you'll see just how easily some Space Marines can die, if they have Terminator armour, of course they'll win, but in their regular Power Armour a well placed Ballistic can tear one apart. I think they would be even, up until the Space Marine's armour failed - remember, while a Spartan's shields can regenerate, you can only blow so many chunks out of ceramite armour, before there are some gaping holes in it.[/quote] The Horus Heresy Space Marines are something like 6 generations behind the modern Astartes. Of course they're a lot weaker.
