I fished another good book: Horse Soldiers: The Extraordinary Story of a Band of US Soldiers Who Rode to Victory in Afghanistan by Doug Stanton.
Below is an excerpt where two soldiers take apart an engine because they flooded the engine crossing a river.
After dinner, they walked outdoors and flipped on headlamps, and Michaels and Black began taking apart the first Gator’s engine with a screwdriver on the Leatherman tool Michaels wore in a leather holster on his belt. They removed the engine’s head and set it aside to dry and covered the open cylinders with a tent made from a tarp they carried, so the pistons would be protected if it rained.
They slept on the packed dirt floor in the house wrapped in their poncho liners and were up at dawn, putting the engines back together.
This feat was amazing to me.
