In Catch-22, Heller, uses parody throughout the novel to illustrate and satirize the military and government, in general. One such parody is the military code that they use. For example, they say that a solider that says that he does not want to go on any more missions shows his sanity because of his fear of death, and therefore is more fit to go on missions than those who are willing to go. Yossarian wants to go home, but he can't do anything...he's trapped. Minderbinder is a parody about thet American dream and most specifically businessmen/capitalism.
