Overview

Field Artillery Sensor Support Marines develop weather data for artillery ballistic computations and conduct survey operations to support accurate artillery fire and counterfire efforts. They operate weather, survey, navigation, distance measuring, and acoustic sensor equipment, as well as computer systems used for computations, digital communications, command and control, and imagery development.

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

Operating GPS receivers, theodolites, inertial navigation systems, and electronic distance-measuring equipment transfers directly to field survey support.

How to prepare: Complete a practical survey-to-CAD exercise that turns field measurements into a checked drawing using AutoCAD Civil 3D.

What the civilian work involves
  • Position and hold the vertical rods, or targets, that theodolite operators use for sighting to measure angles, distances, and elevations.
  • Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.
  • 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)
  • Autodesk AutoCAD Civil 3D
  • ESRI ArcGIS software

Geographic Information Systems Technologists and Technicians

Military survey operations and computer-based imagery development provide a foundation for producing civilian spatial data layers and maps.

How to prepare: Build an ArcGIS portfolio project that imports GPS points, combines them with imagery, and produces a map with documented coordinate systems.

What the civilian work involves
  • Produce data layers, maps, tables, or reports, using spatial analysis procedures or Geographic Information Systems (GIS) technology, equipment, or systems.
  • Design or prepare graphic representations of Geographic Information Systems (GIS) data, using GIS hardware or software applications.
Civilian tools and software (examples)
  • ESRI ArcGIS software
