@RedRyan: You where right all along. One of my friends in college told me that GI Combat series was going to be canceled before the Christmas Holidays. Hunted Tank was a good series to read and Unknown Soldier was also going to end too. DC has canceled a lot of good stuff due to poor readers and sales like Captain Atom, Blue Beetle, Voodoo, JLI, etc.
In years to come they might bring back the series and start over again.
The Good News is that Animal Man and Swamp Thing series fighting off the ROT WAR is doing well. Batman series Death In a Family crossover, Superman crossover and Justice League series is doing good and not canceled.
Phatom Stranger is a good book to read.
I wonder if Booster Gold will be seen again? I have not seen him since JLI Annual.
