"the dead man in Yossarian's tent"

This is the first reference to a guy we’ll hear a lot about, but not in any great detail. Naturally, it’s startling to hear about a dead man in any case, but that there should be one in Yossarian’s own tent is particularly unsettling. Of course, gradually we’ll be allowed to understand that there isn’t really a body in Yossarian’s tent; the “dead man” is yet another one of those casual paradoxes that populate this book: an Absence that’s a Presence.
