Notes & Sources

  • C3 (Well Drilling) 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 the operation of well- drilling equipment." Award requirement: "Must successfully complete the Water Well Drilling Class C, USN Naval Training Center, Port Hueneme, CA." Restrictions: "For use with MOS 12N 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.
