Read the excerpt about two men trying to bury a dead soldier right in the middle of a battle.
"Yes," said Lean. The two privates stood waiting, bent over their implements. "I suppose," said Lean, "it would be better if we laid him in ourselves."
"Yes," said the adjutant. Then apparently remembering that he had made Lean search the body, he stooped with great fortitude and took hold of the dead officer's clothing. Lean joined him. Both were particular that their fingers should not feel the corpse. They tugged away; the corpse lifted, heaved, toppled, flopped into the grave, and the two officers, straightening, looked again at each other—they were always looking at each other. They sighed with relief.
The adjutant said, "I suppose we should—we should say something. Do you know the service, Tim?"
"They don't read the service until the grave is filled in," said Lean, pressing his lips to an academic expression.
"Don't they?" said the adjutant, shocked that he had made the mistake.
"Oh, well," he cried, suddenly, "let us—let us say something—while he can hear us."
"All right," said Lean. "Do you know the service?"
"I can't remember a line of it," said the adjutant.
Lean was extremely dubious. "I can repeat two lines, but—"
"Well, do it," said the adjutant. "Go as far as you can. That's better than nothing. And the beasts have got our range exactly."
Lean looked at his two men. "Attention," he barked. The privates came to attention with a click, looking much aggrieved. The adjutant lowered his helmet to his knee. Lean, bareheaded, he stood over the grave. The Rostina sharpshooters fired briskly.

PCR stands for Polymerase Chain Reaction. It is a method to analyze a short sequence of DNA or RNA and is used to reproduce (amplify) selected sections of the nucleic acid. Untold numbers of copies can be made of the DNA in just a few hours.
PCR amplifies the regions of DNA that it targets and can therefore be used to analyze extremely small amounts of sample. This is often critical for forensic analysis, when only a trace amount of DNA is available as evidence.
