In Principle The law of armed conflict is a compromise based on a balance between military necessity, on the one hand, and the requirements of humanity on the other. ~ AP I Commentary
What is It? Consists of the necessity of those measures which are indispensable for securing the ends of war, and which are lawful according to the modern law and usages of war – Francis Lieber, 1863
Kriegsraison vs. Kriegsrecht kriegsraison geht vor kriegsrecht / Kriegsmanier "the necessities of war take precedence over the rules of war" kriegsraison
Targeting I “IHL is a compromise between humanity and military necessity, a compromise which cannot always satisfy humanitarian agendas, but which has the immense advantage that it has been accepted by states as law that can be respected even in war.” –Marco Sassoli (former ICRC legal advisor) “Military necessity is an attempt to realize the purpose of armed conflict, gaining military advantage, while minimizing humanitarian suffering and physical destruction; it is battlefield violence counterbalanced by humanitarian considerations.” – Gary Solis LOAC’s Compromise
Downey Article - 1953 Urgent Need admitting no delay Measures indispensable for forcing quick surrender Regulated violence Measures not forbidden Is this still true?
As Defined Today That principle which “Justifies those measures, not forbidden by international law, which are indispensable for securing the complete submission of the enemy as soon as possible” - FM 27-10
FM 27-10 “The prohibitory effect of the law of war is not minimized by “military necessity” which has been defined as that principle which justifies those measures not forbidden by international law which are indispensable for securing the complete submission of the enemy as soon as possible. Military necessity has been generally rejected as a defense for acts forbidden by the customary and conventional laws of war inasmuch as the latter have been developed and framed with consideration for the concept of military necessity.” ~ FM 27-10, para 4 Targeting I
(b) The United Kingdom understands the term "feasible" as used in the Protocol to mean that which is practicable or practically possible, taking into account all circumstances ruling at the time, including humanitarian and military considerations.

But German artillery and gunfire raining endlessly down from the mountain caused Allied troops to imagine that the monastery was the cause of their misery: it was the only thing they could clearly see. One day two American generals flew a Piper Cub over it and believed they spotted Germans in the courtyard. Another general flew by and saw nothing, and a French commander, Gen. Alphonse Pierre Juin, pleaded with the Americans to spare the building, saying an attack was folly. Those in charge didn’t want to listen. “This monastery has accounted for the lives of upwards of 2,000 American boys,” reported an American Army Air Corps lieutenant colonel to his superiors the day before the attack. “The Germans do not understand anything human when total war is concerned. This monastery MUST be destroyed and everyone in it as there is no one in it but Germans.” Mr. Atkinson said: “Crummy intelligence leads to crummy tactical decisions. There was a lot of bad intel floating around and a lot of cherry-picking of it.” ~ A Ruined Abbey, a Parable of War, NYT, 30 Sep 2007
It was Clark who ordered the attack. He would spend much of the rest of his life defending this decision, one he had been reluctant to make. He wasn’t sure Germans did occupy the abbey, and instead of stopping them, he predicted, destroying it would only give them another place to hide. “If the Germans are not in the monastery now, they certainly will be in the rubble after the bombing ends,” he warned. But he was overruled. On Feb. 15, the Allied planes came, 250 of them dumping 1,300 bombs and 1,200 incendiaries. Scores of refugees, mostly women and children who had sought shelter in the abbey, were slaughtered. “Four hundred civilians,” Mr. Atkinson said, “is as good a guess as any. But no Germans. That’s quite clear to history.” Maj Gen Mark W. Clark ~ A Ruined Abbey, a Parable of War, NYT, 30 Sep 2007
Military Necessity What is it? What are its limits? Who decides? How do we judge decisions?
Rendulic Standard In determining whether an attack was proportionate it is necessary to examine whether a reasonably well- informed person in the circumstances of the actual perpetrator, making reasonable use of the information available to him or her, could have expected excessive civilian casualties to result from the attack

Military Necessity Definition & Sources, Limits –AP I definition: MN = measures essential to attain the goals of war, and lawful IAW LOAC (rules out Kreigsraison) –If a military act is not prohibited in LOAC, it is permissible, subject to the limit of necessity itself as well as of the Martens Clause Commander’s Discretion, “Rendulic Rule” –LOAC filled with general principles which must be applied in good faith –LOAC gives commanders discretion to decide military necessity (“have confidence in the wisdom of the generals”) –Commanders’ decisions are judged based on the Rendulic Rule, CIL –Rendulic Rule = Did the commander act reasonably based on the information reasonably available to him/her at the time –Criminal liability likely only attaches if commander knowingly and intentionally violates a rule or principle of LOAC
