Notes & Sources
- NOOCS Part A (Edition 96, Jul 2026) defines officer designator 510X as: “A Civil Engineer Corps Officer”
- The paired billet row (5100) is “requiring Civil Engineering specialty”. a billet requirement, not a qualification conferred on every 510X officer.
- The designator row is an identity/qualification statement, not a duty description, so occupation-specific skills, career paths, and credential recommendations are not published here; duties depend on the billet and community qualification.
