Second...If you begin to think that a Special Forces Soldier is so one-dimensional that if there isn't a civilian version of 18E you won't find work, you need to reevaluate.
Third...As a retired 18E I can tell you that there is a ton of work out here either in emergency planning, contingency communications, field communications support, spectrum management etc...etc....etc.. You provide your own limitations.
