> they have an air purifier built-in to their armor, Space Marines can breath pretty much any airbourne substance, regardless of toxicity, even without armour. > they can see in dark very damn well, Ditto > have ninja-like (no pun intended) reflexes and lighting speeds. Ditto > Plus, they're smaller, more agile and can operate any damn thing throw at them. In this case, smaller isn't better. > I'm sorry to say this, but an SM looks like a human tank of metal and nothing more: slow, bulky, lame and very retarded. Despite their bulk, Space Marines are incredibly fast due to their training, augmentations and enhanced servos within the power armour. > Spartan-II with an energy sword; fight over. This was a debate involving standard equipment. An energy sword isn't. > More than an average are above seven feet tall encased in Titanium-ally armor. All Space Marines are well above 6.5 feet, at least, and have armour of pure adamantium, the strongest substance know to man in the 41st Millenium. > With that and the given examples above, they can jump an easy two or three meters, Ditto >run up to 40KPH easily, Ditto > withstand falls from orbit and be alive, gel embedded in the armor for cushion and supreme reflexes (300% faster than any Marine) Okay, but what use is that in a fight? Also, see previous points. > Also, their bones are titanium based, giving their muscles more to use plus being surgically strengthened with the drugs.
