Catch-22

So as I'm reading this book I'm noticing so many contradictions. Every character tells a story and in the next chapter says that didn't really happen. Or if a character is said or shown to always behave a certain way, then in the next paragraph they'll behave the completely opposite. What I'm thinking is that the author is trying to make fun of the fact that war is a contradiction. You'll taught your whole life not to kill and then your  awarded medals for killing people for your country. I believe the book is a satire because the author is taking the contradiction and confusion of war and is making fun of it by personifying those traits through the characters. When readers read the book and realize how ridiculous the characters are because of how they behave it's basically the authors way of saying war itself is ridiculous.

CATCH-22

So I really love the book so far, but I have a question: Is the "dead man" in Yossarian's tent real? It seems to me that Yossarian is crazy so you have to watch how much you believe of his stories and tellings of things. He tries to make his stories as crazy as possible so that the reader believes that everyone but him is crazy. That being the case, it's hard to tell what really happened at what didn't. So I'm trying to figure out if the dead man in his tent is real or not. If it isn't, McWatt wouldn't be able to use the dead man's gun to shoot mice at night. But then again, maybe that's really McWatt's real gun and Yossarian's just trying to come up with another crazy story by saying McWatt stole the gun from a dead man...
