Imperial Fists! They cannot miss this crusade.
Second choice Iron Hands

Iron Hands ftw
And of them, Manus was the key. Implacable. Unshakeable. If he was at your side, he would never break.
Now, it seems, he is gone. Gone. Dead. Brother. Friend. Warrior. Leader. Ultramar’s most stalwart ally.
from "Know Now Fear"

Imperial fists. Gotta love the eternal rivalry with the Iron Warriors.

Fists, though they are all awesome in there own ways.

Salamanders, because for me they represent all that a Space Marine ought to be: a champion of Humanity, fighting for the people of the Imperium, not for personal glory or because they were told to.

Plus, flamers.

I hear you there Brother !

The sons of Dorn of course. A more loyal chapter there is none...

Fists +1

I wanna say Alpha Legion but I donno if you guys would count that.

Raven Guard. You need space ninjas.
