It&#x27;s probably not a legitimate concern between two advanced regular militaries who follow the laws of war and would bury your dead with respect if they can&#x27;t actually return them to you, but if you left a uniformed western body where ISIS can get it then I&#x27;m sure that would end very nastily indeed, with photos on social media and so on. Think of the military contractors burned and hanged on that bridge in Iraq.<p>&#x27;No man left behind&#x27; is practical, both for the propaganda reason above and unit morale, not about showing off. But like most things in military life I never heard anyone ever bombast about &#x27;no man left behind&#x27; like they do in the movies.
