 When we got to Afghanistan, that was 2007 and 2008. When we got to Afghanistan in 2010, the Taliban had less resources, so they actually made their IEDs simpler. And because they were simpler, they functioned more often. There was less to go wrong. So rather than focusing on out-tricking us with technology like remote control or IR sensors, they just made really solid loop circuit, just like a flashlight you buy at the dollar store. Hit the switch, the light bulb comes on. For them, you hit the switch, the bomb blows up.
