What job can you get on the civilian side after being a combat engineer in the Army?

Anything construction, Army Corp of Engineers, demo, with a degree maybe bridge or road design, etc.

Look into the MOS crosswalk that sfl-tap mandates. It will tell you everything that's one to one with the private sector.

I would go to trade school, 12B is a good lead in for EOD, or Engineer, but doesn't really line up with much directly.
