5713 CBRN Defense Specialist
The 5713 is not a different specialty. It is the career milestone for a CBRN Defense Specialist who has earned the experience, additional training, and responsibility that separate an entry-level 5711 from a senior technical advisor to a commander. That distinction matters in a field where a single inaccurate assessment can result in the wrong protective posture for an entire unit. If you are already a 5711 thinking about your path forward, this is the designation your career is built toward. If you are researching the CBRN field as an applicant, understanding 5713 tells you where a serious CBRN career ends up.

Job Role and Responsibilities
The 5713 CBRN Defense Specialist serves as a senior chemical, biological, radiological, and nuclear specialist within Marine Corps units and MAGTF headquarters. Marines who hold 5713 provide experienced technical advising to commanders and staffs, direct complex CBRN operations including reconnaissance and large-scale decontamination, and mentor junior 5711 Specialists. The designation indicates a Marine who has progressed from basic qualification to senior technical competence within OccFld 57.
Daily Tasks
Senior CBRN Specialists handle a broader and more complex set of responsibilities than entry-level counterparts. Daily activities include:
- Advising commanders and staffs at battalion, regimental, or MEF level on CBRN threats, vulnerability assessments, and protective postures
- Planning and directing CBRN reconnaissance operations and decontamination site operations
- Managing the unit’s CBRN training program, ensuring all unit Marines maintain baseline CBRN defense proficiency
- Mentoring and technically directing junior 5711 Specialists
- Integrating CBRN considerations into operational planning processes
- Monitoring and analyzing CBRN threat intelligence products
- Coordinating with joint CBRN elements during exercises and operations
Specific Roles
| Classification | Code | Description |
|---|---|---|
| PMOS | 5713 | CBRN Defense Specialist (advanced designation) |
| Entry level | 5711 | CBRN Defense Specialist (beginning of career) |
| Warrant | 5702 | CBRN Defense Officer (warrant officer path) |
The 5713 designation applies to experienced CBRN Specialists who have met the time-in-grade, training, and proficiency requirements that distinguish senior from junior specialists within the occupational field.
Mission Contribution
At the 5713 level, CBRN Specialists operate at the intersection of technical expertise and command advisory. A senior specialist who correctly identifies a contamination pattern, recommends the appropriate decontamination approach, and adjusts the unit’s MOPP posture in time prevents casualties. An incorrect assessment or an incomplete decontamination plan creates exactly the vulnerability that CBRN threats are intended to exploit. The 5713 Marine is the unit’s most experienced person on that problem.
Technology and Equipment
Senior CBRN Specialists work with the same detection and protection systems as 5711 Marines, but with greater technical depth. Advanced detection platforms, data integration systems for CBRN reconnaissance products, and the administrative tools for CBRN planning and reporting are standard. Knowledge of evolving CBRN threat agents and the detection equipment designed to identify them is a continuous professional requirement.

Work Environment
Setting and Schedule
Senior CBRN Specialists work at battalion, regimental, and MEF staff levels. The environment is a combination of office-based planning work and field exercises where CBRN capabilities are integrated into combined arms training. Senior Specialists are involved in command planning processes, not just technical operations.
Leadership and Communication
At the 5713 level, the Marine is the senior CBRN technical voice in most units. Communication must be effective with commanders, staff officers, and non-CBRN-specialist Marines who need accurate, clear guidance on protective measures. The leadership challenge is conveying urgency and precision when the threat is invisible.
Team Dynamics and Autonomy
Senior CBRN Specialists typically work with junior 5711s as a small team. The senior specialist provides technical direction and mentorship while the unit CBRN officer (5702) handles command-level advising. At lower command levels where no officer CBRN specialist is present, the senior enlisted CBRN specialist may be the primary advisor to the commander.
Job Satisfaction and Retention
Marines who reach 5713 have typically committed to the CBRN field as a career specialty. The satisfaction of being a recognized technical expert and of training a field that units depend on in the most serious environments tends to sustain retention in the senior ranks.

If that combination fits your career goals, the path from 5711 to 5713 is a clear and purposeful one.
Potential Challenges
Marines who find the preparation-heavy nature of CBRN training tedious, or who want broader operational variety than a single technical specialty provides, should consider different MOS fields before committing to the CBRN path. The field is narrow, and senior CBRN billets are not present at every installation or in every unit type.
Career and Lifestyle Alignment
5713 Marines who separate after a full career have one of the stronger federal job candidacy profiles in the enlisted force. Senior CBRN expertise, security clearance experience, and demonstrated command advisory experience are valued in federal emergency management, military contracting, and DoD civilian CBRN programs.
