Combat engineers tend to be fanatical about their profession. Perhaps it’s a prerequisite. De-mining, which is usually done completely by touch—probing the earth with plastic rods, then feeling each mine to check for antihandling booby traps and removing it by hand—is highly stressful. According to their own guidelines, engineers are not supposed to pull more than twelve antitank mines a day, given the toll it takes on their nerves.
