IDF medics are measured by the metric CFR (case fatality rate) – the percentage of wounded soldiers evacuated from the battlefield whom they failed to save. In the Second Lebanon War in 2006, the CFR stood at 15%. In the Gaza War, the CFR is 6.5%, due to more medics, faster evacuation and blood products.
