Cenepa War
Figures given for losses during the Cenepa War vary widely, especially regarding human casualties. Ecuadorian military sources put the casualties at 34 killed recognized by Comando Conjunto de las FFAA del Ecuador and 154 killed and wounded recognized by Asociación de ex combatientes del Cenepa, Quito, Ecuador. As of February 2005, an Ecuadorian Cenepa war veterans' association had a membership of 131 ex-combatants, some of them with long-term health disorders caused by the war.
ALDHU, a human rights NGO, has put the total number of mortal casualties for both sides at around 500. This figure was also given by Ecuadorian senior officers after the war, reflecting the fact that Peruvians found themselves attacking well-protected Ecuadorian positions and subjected to continuous ambushes and well-aimed artillery and rocket fire from the heights of the Condor range.
Civilian casualty ratio
According to most sources, World War II was the most lethal war in world history, with some 70 million killed in six years. The civilian to combatant fatality ratio in World War II lies somewhere between 3:2 and 2:1, or from 60% to 67%. The high ratio of civilian casualties in this war was due in part to the increasing effectiveness and lethality of strategic weapons which were used to target enemy industrial or population centers, and famines caused by economic disruption. An estimated 2.1–3 million Indians died in the Bengal famine of 1943 in British India during World War II. A substantial number of civilians in this war were also deliberately killed by Axis Powers as a result of racial policies (for example, the Holocaust) or ethnic cleansing campaigns.
