I haven't collected BA war for a couple years, but when I did I was really into it. I managed to pick up OOAW 235-255, OFF 123-181, GIC 138-154, SSWS 151-204, Unknown Soldier 205-268, and a few other odds and ends.
Here's some of my key BA wars books...
It was thanks to these forums that I learned the importance of this first book. Hail to the King, baby!
I actually bought this one from Mile High...and it's not too shabby.
My favorite BA war character. The stories in SSWS just keep getting better and better. And here's his real first appearance!
"Now--Exploding in His Own Battle Blockbuster Mag!"
