Codex Astartes: Volume CXVIIIIII, Chapter XVIIII, Section VIIII
Steve.
Seriously, what is UP with that guy? Remember that one time with the land raider? that was crazy. Or the time he got captured by Orks, but then they made him their king? Or the thing with the fish?
The point is, Steve is a great guy to have around, really lightens up the Battle Barge, tells all the good jokes. However, he wouldn't know how to burn a heretic dancing in gasoline. I've got no idea how he survived the trials, much less the centuries of battle he's been through.
I mean, I wouldn't say a bad word against the guy. He's like a brother to me, and his hearts are in the right places, but you kind of have to plan your tactics around him if you know what I mean. And don't let him use the plasma canons.
Remember, know the enemy, know the ground, know where Steve is, and you need fear no defeat.
