The photo was taken after a USMC EOD NCO was blown up by a command detonated booby trap. The Gunny with the single up raised middle digit is "flipping off" the terrorist who triggered the device while the Gunny was dealing with an IED. Despite being burned and wounded by shrapnel, the Gunny's fighting spirit was not harmed at all. He returned to EOD duties a month later after recuperating from his injuires.
