The wounding patterns observed in Iraq and Afghanistan from 2005 to 2009 differ from previous conflicts. Explosive mechanisms accounted for 74·4% of combat casualties, which is a higher percentage than in previous US conflicts. A progressive increase in the use of explosive mechanisms in Afghanistan, eventually equaling that in Iraq, was observed during the study period.
