When Gregg left, Murphy examined the papers. As Gregg said, the papers were a test of their knowledge of military procedure. There were yes and no questions: questions such as Describe procedure to infiltrate enemy lines, Describe procedure for establishing night patrols, Describe alternate code system. Hundreds of questions.

"I said look, not talk!" Murphy rose and glared at Hank. "You're stupid," he added.

"Well, so what?"
