It would be like that, but 10x worse. Oh absolutely and I think the book agrees. I recall them describing battles where the piles of dead zombies where so high the soldiers couldn't see the next wave approaching. The hard part was never killing zombies but making sure you killed all the zombies before you ran out of fuel and bullets.
