Catch-22 Chapter 8: Lieutenant Scheisskopf
"History did not demand Yossarian's premature demise, justice could be satisfied without it, progress did not hinge upon it, victory did not depend on it. That men would die was a matter of necessity; which men would die, though, was a matter of circumstance, and Yossarian was willing to be the victim of anything but circumstance. But that was war." Chapter 8, pg. 75
In a flashback to cadet school, Yossarian remembers Lieutenant Scheisskopf's fanatic love of parades and hatred of Clevinger. Scheisskopf's greatest victory in parade competition was teaching his men to march without swinging their hands. Clevinger, too smart for his own good, is brought up on charges before the action board.
"The case against Clevinger was open and shut. The only thing missing was something to charge him with." Chapter 8, pg. 80
Yossarian only volunteered for this extra aviation training because it delayed his entry into combat duty. But Yossarian ends up falling in love with Dori Duz and having sex with Lieutenant Scheisskopf's wife.
