I wanted to highly recommend the book "Tooth and Nail", by Craig DiLouie. It's available from Amazon either in hard copy or as a Kindle download.
It's a story about a small Army unit that has been pulled out of Iraq and sent to New York City to help cope with a flu pandemic. The flu mutates, a large percentage of its victims become zombies, and the fun begins. The book does an excellent job of exploring the personality dynamics within an Army unit, and of showing just how effective military weapons are on things made out of flesh and blood, be they human or zombie.
A number of the characters and situations in this book are going to remind you of "We're Alive". You'll recognize counterparts of Michael, Angel, Saul, and even Burt among the soldiers. And you'll definitely sympathize with the survivors in the apartment complexes, surrounded by streets full of abandoned vehicles and hordes of zombies.
