Overview

The Electrical Equipment Maintenance (Power Station) specialty identifies positions requiring soldiers qualified in electrical equipment maintenance. The required qualifications cover unit, direct support, and general support maintenance of equipment used in electric power production.

Notes & Sources

  • S3 (Electrical Equipment Maintenance (Power Station)) is an Army Additional Skill Identifier (proponent: U.S. Army Engineer School), not a standalone military occupation.
  • Authority scope: "Identifies positions requiring Soldiers qualified in unit and direct support and general support maintenance of electrical equipment used in electric power production." Award requirement: "Must successfully complete the Prime Power Production Specialist Course, Ft Belvoir, VA." Restrictions: "For use with MOS 12P only." The identifier alone does not establish a civilian occupation; occupation-specific skills and career guidance depend on the holder's primary MOS and actual duties.
