"The war tried to kill us in the spring" from The Yellow Birds always stuck with me, for its complete decoupling of the war from the men who had come thousands of miles to fight it.

“The war tried to kill us in the spring. As grass greened the plains of Nineveh and the weather warmed, we patrolled the low-slung hills beyond the cities and towns. We moved over them and through the tall grass on faith, kneading paths into the windswept growth like pioneers. While we slept, the war rubbed its thousand ribs against the ground in prayer.
