 Both used IEDs, improvised explosive devices, but they employed them and made them in totally different ways. So that 10 months I had in Iraq as an on-the-job training with EOD, I saw a certain type of IED, and they didn't function very often. They usually, by the time we found them, something didn't go right with them, and they weren't going to blow up, and EOD's job was just basically to dispose of it. Right.
