Most of you don't know this, but I just got into 
40k after having played Fantasy for a while in my teen years. I played Chaos in Fantasy, so playing the same in 
40k felt pretty natural.
 
 So I got the 
CSM codex and read through it and I sort of got stuck on the Red Corsairs. I mean, Chaos space pirates, what's not to like!? 
 
 
 
 Next thing I thought of was what squads that would be suitable considering the legion's background. I know it's not really that important, but I like fluff!
 
 
 Anyway, I'm currently thinking along the lines of "boarding parties" and heavy support fire, so I reckon at least two Raptor squads and one Havoc Squad, along with two regular 
CSM squads, some seriously beefed up Termies and an 
HQ. I know Huron has his own biker gang in the fluff but so far my bikes are the first thing to die in every game, so I might scrap the idea of bikes altogether (or just get better at using them).
 
 Seeing as they are ship-based fighters I reckon they don't really use tanks that much, even when deployed onto planets. What do you guys think?
 
 If only there were chaincutlasses, that would be perfect! I really like the pirate aspect of it and feel like emphasizing on that.
