Sample Insights:

1) Perspective is important to recognize and understand in life. Americans could take a lesson in perspective from the Afghans Dan Crenshaw met and fought against during his 2012 deployment in Afghanistan, as every day they were worried about their safety and well being.

2) IEDs, improvised explosive devices, changed the way war was fought in Afghanistan. It no longer was a straight-up firefight, but a maze that could be traversed only in a single-file line to minimize the risk of stepping on an IED – all while being shot at.
