War is a state of armed conflict between societies. It is generally characterized by extreme aggression, destruction, and mortality, using regular or irregular military forces. While some scholars see war as a universal and ancestral aspect of Human nature, others argue it is a result of specific socio-cultural or ecological circumstances. The earliest recorded evidence of war has been determined to be approximately 14,000 years old.
The Iraq War began on 20 March 2003, with the U.S., joined by the United Kingdom and several coalition allies. The U.S. formally withdrew all combat troops from Iraq by December 2011 but became re-involved in 2014 at the head of a new coalition. By the end of 2015 4.4 million Iraqis had been internally displaced and an estimated 500,000 Iraqis had died as a result of the conflict.
Despite representing 15% of the US troops in Iraq, female soldiers only account for 2% of the war casualties, with half of them being reported as suicides caused by Post Traumatic Stress Disorder. 30% of military women are raped while serving (14% of them gang raped), 71% are sexually assaulted, and 90% are sexually harassed. Women were 15 times more likely to be raped by their fellows than die in the war.
