Mild Bouts of Confusion Happening

I can see why this book is on so many "best of" lists, but it's driving me.  The way Heller has his characters talking in circles is, I assume, supposed to be a commentary on the futility of war, but I'm beginning to wonder if anything ever really happens in this book. And there's something else - I'm quite a few chapters in, and I haven't seen another reference to the chaplain - something I figured was important since Heller decided to start the novel off with this revelation.  Really wondering how this book is going to progress.
