Overview

A Fleet Marine Force Reconnaissance Corpsman provides medical and operational services during direct action and reconnaissance operations, including basic life support, paramedical care, and minor surgical procedures. The corpsman supports operations using open and closed circuit SCUBA, conducts underwater searches, maintains diving equipment, operates hyperbaric chambers, and cares for patients undergoing hyperbaric treatment.

Minimum clearance: Secret

Core Skills

  • Recognition of diving illnesses and toxicity
  • Hyperbaric chamber operation and patient tending
  • Underwater searches and SCUBA equipment maintenance
  • Injury prevention for diving and amphibious operations

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.

Emergency Medical Technicians

Military basic life support and routine and emergency patient care provide directly relevant experience for prehospital EMT work.

How to prepare: Ask the State EMS Office to assess your existing certifications and documented military education against its entry pathway before enrolling in additional coursework. National Registry certification alone does not authorize practice; state authorization must be addressed.

What the civilian work involves
  • Administer first aid treatment or life support care to sick or injured persons in prehospital settings.
  • Assess nature and extent of illness or injury to establish and prioritize medical procedures.
  • Comfort and reassure patients.
Civilian tools and software (examples)
  • Informed EMS Field Guide

Commercial Divers

Military underwater searches, SCUBA maintenance, and decompression knowledge overlap with commercial diving duties.

How to prepare: Have a commercial diving employer assess your military training records and dive logs against its assigned diving modes, equipment, and work tasks to identify specific training gaps.

What the civilian work involves
  • Check and maintain diving equipment, such as helmets, masks, air tanks, harnesses, or gauges.
  • Descend into water with the aid of diver helpers, using scuba gear or diving suits.
  • Obtain information about diving tasks and environmental conditions.
Civilian tools and software (examples)
  • Diving logbook software
  • Diving table software

Notes & Sources

  • If using the National Registry EMT Full Education Program Pathway, a state-approved EMT course must have been completed within the past two years and verified by its program director; the pathway also requires the Registry examination and state-approved BLS skills competency.
  • For commercial diving covered by OSHA 29 CFR 1910.410, assigned tasks must match experience or training in the relevant equipment, diving mode, and emergency procedures. CPR and first aid training are required, along with diving physics and physiology training for personnel exposed to or controlling hyperbaric exposure; temporary impairments affecting safety preclude diving or hyperbaric exposure.
  • If pursuing ADCI classification, Entry Level requires 625 documented hours of formal instruction or a recognized equivalent. Air Diver requires at least 100 field days and 30 working dives, with only surface-supplied dives counting toward its requirements. These are ADCI program standards, not a universal government license.
