In the early days of the Iraq War, troops were riding around in Humvees with almost no armor on them. There was a scandal about it, and within a few years the trucks got up-armored with thick steel plates, which solved one problem but created another.
"Some genius thought about up-armoring. Good! But they didn't do anything with the brake systems," says George Wilmot, who was riding an armored Humvee in 2009, leaving a hilltop base in Mosul.
"We took some small arms fire ... my driver took us off a cliff," says Wilmot.
