The Eternity Brigade (Large Print Edition) - Stephen Goldin - Bog

Hawker was a good soldier -- so good, in fact, that the Army asked him and his buddies to sign on for an extended hitch. What they couldn't know was that the extension would last forever. Century after century, war after war, Hawker and his comrades were re-animated over and over to fight on alien planets with ever more advanced weapons. The reasons for the wars were incomprehensible, but that didn't matter. All that counted was the fighting itself. From incarnation through incarnation, one goal remained in Hawker's mind. Somewhere, somehow, there had to be a way out of the loop. And he was determined to find it.
