My dad is a First Sergeant in the 766th EOD company, United States Army. Based on what I have been told by him, EOD can be very disturbing. Normally they use robots, but robots can only do so much. Some times it just takes some man power. During his deployment in Iraq he was forced into situations where he was forced to walk through 3ft deep or so sewage. I figured explosions, sewage, and dirt might b right up your alley.
