Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Surveying and Mapping Technicians

Plotting survey data on firing charts and determining target coordinates transfer directly to the spatial-data work of mapping technicians.

How to prepare: Complete an introductory GIS course and create a sample overlay map in ESRI ArcGIS software, checking its coordinates and layers for accuracy.

What the civilian work involves
  • Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.
  • Monitor mapping work or the updating of maps to ensure accuracy, inclusion of new or changed information, or compliance with rules and regulations.
  • Produce or update overlay maps to show information boundaries, water locations, or topographic features on various base maps or at different scales.
Civilian tools and software (examples)
  • ESRI ArcGIS software
  • Autodesk AutoCAD

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Preventive maintenance and routine testing of fire-control equipment provide a foundation for civilian equipment service work.

How to prepare: Take a hands-on electronics course that includes circuit-diagram reading, test-equipment use, and fault diagnosis before pursuing industrial equipment repair positions.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Set up and test industrial equipment to ensure that it functions properly.
  • Inspect components of industrial equipment for accurate assembly and installation or for defects, such as loose connections or frayed wires.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
