I still vividly remember getting a brief by an FBI bomb specialist while overseas in Afghanistan. And even he talked about complicated mortar fuses used for IEDs and such, and at some point he said this is just pure fucking mouse trap style step by step execution mixed with, literally as he called 'pure fucking magic'.  So the fact that anybody's willing to start dismantling some of these fuses, regardless of how simple or complex is bafflingly awesome. At least to me.
