[MSguardsmen]

well i finally gave into temptation and bought a space marine codex. and i think ill start an ultramarines list depending on how my list making goes ( i simply love the Marneus and Honor Guard models look)

so who the heck is this sergeant that has to be in almost every squad? does he have the same stats as a regular space marine ... in his squad? if so why the heck is he squad leader?

also what are the traits for a ultramarine army?
