When a soldier in the field of battle is under attack in a small village and comes upon a villager who could be a combatant or a civilian, what rules govern how that soldier should act? If the soldier detains the villager and determines that the villager is an unaffiliated combatant, what do the rules of detention require? In The War on Terror and the Laws of War, six legal scholars with experience as military officers bring practical wisdom to the contentious topic of applying international law to the battlefield. The authors apply their unique expertise to issues that have gained greater urgency during the United States' wars in Iraq and Afghanistan: including categorizing targets and properly detaining combatants. The modern battlefield has proven to be a difficult arena in which to apply traditional legal rules. The War on Terror and the Laws of War brings clarity to the subject with an insider's perspective.
