Notes & Sources
- NOOCS Part A (Edition 96, Jul 2026) prints officer code 713X as “Engineering Technician (Surface)…”, paired with its Chief Warrant Officer billet row (billet 7130 requiring the specialty); the row states who holds the code and which specialty the billet requires, not what duties every holder performs. See the cited block for the exact pairing text.
- Because the Navy carries no duty, training, or clearance prose at designator level, occupation-specific recommendations are not published here; a 713X officer’s duties depend on the assigned billet.
