Army · 12N
Horizontal construction engineers operate heavy equipment to build roads, airfields, and earthworks: grading, excavation, site preparation, and materials work. That maps directly to civilian heavy-equipment operation, construction, and public-works directions.
These are the civilian jobs the U.S. Department of Labor maps to 12N, plus the roles most closely related to them—ordered from the closest match. Think of them as a floor, not a ceiling: see what each role involves and pays, start where your Horizontal Construction Engineer experience already fits, and build toward the rest.
