SyFy greenlighted Battlestar Galactica: Blood & Chrome about young Bill Adama in the Cylon War. Now that I'll watch.
I'm interested, but wasn't Adama's first mission at the end of the war? 
Don't think so. Are you thinking about those webisodes they did? They referenced him fighting in the war many times on BSG if I recall.
The webisodes had the story of his first combat mission. I'd have to see them again. I have a recollection that the war ended
w00t!
