"They called guys like us war dogs.  Bottom feeders who make money off of war without ever stepping foot on the battlefield.  It was supposed to be derogatory, but... we kind of liked it."  -David Packouz

War Dogs is about two men, Efraim Diveroli and David Packouz, who start a company AEY.  They work with US arms deals with US Department of Defense.  They start off making millions and living a great life.  But after scoring a $300 million contract they find themselves working with so very shady people.  They break a contract by repackaging and reselling Chinese ammunition and giving it to the war in Afghanistan.  This is against the US embargo on Chinese fire arms.. This scores the two and many more severe consequences and they get 4 years in federal Prison.
