So the protagonist in my WW3/post apocalyptic story... Not sure how he is as the main character, but here are some details. Sam Tanner grew up in Denver during the build up to the war. He ran with a gang to make ends meet and was arrested during a bank robbery, told that he would either go to war or go to jail. So Sam decides to join the military, where he is sent to US Army basic training and later selected for a new Special Forces program known as Archangel. Sam makes it through all the training and becomes a member of the new unit, participating in several operations leading up to the actual war itself. Sam is constantly torn, wanting to return To a life of freedom, to go AWOL and escape the sentence he was given. On the other hand he doesn't want to betray his brothers in the team and has a growing sense of purpose in the military compared to being a street criminal. As the plot progresses and the world 'ends', Sam eventually becomes the hero of the story, traveling across ruined America in his adventures.
