Thanks for the hearty welcome, Craig!
Glad you liked the blog. I hope to showcase many a FUBAR game when I get my table up and running. In the middle of a house move now but FUBAR was an instant classic with me.
SOCWAD is the modern, late 20th century Iron Ivan Supplement for their popular Disposable Heroes skirmish rules. I merely took SOCWAD one step further and introduced it into the 40k universe. Think Dan Abnett novels and there you go. (one heck of a writer, isn't he?). Would be more than happy to share the Google Doc with you that have the stats for marine, guard, cultist, etc. I post AAR's on the Iron Ivan yahoo group page all the time and no one seems interested...
I have been working on a set of micro armour rules that seem right up the group's alley, however. I've had them since college in various forms and they might work very nicely for large, epic styled battles with much more fluid action than a more standard wargame sequence. Right now they're written for late 20th century actions, but, I think, easily converted for a sci fi genre. I've dubbed them "Steel Echelons"
