Marine Intelligence and Cyber MOS Jobs

Three fields people keep mixing together

Marine intelligence and cyber jobs do not live in one box. Searchers often mix analyst work, cyber operations, signals intelligence, electronic warfare, and clearance-heavy support jobs into one category because all of them sound technical and classified. The Marine Corps organizes them more specifically than that.

The right starting point is distinguishing OccFld 02, OccFld 17, and OccFld 26 before looking at individual MOS options. These three fields represent different mission types, different entry patterns, and different civilian career paths, even though they overlap in the clearance environment.

The split matters because the work, entry pattern, and long-term civilian transfer are different in each field. Treating them as interchangeable options because they all involve clearances and technical-sounding missions produces misaligned MOS choices.

OccFld 02 Intelligence: analysis and human-source work

The 02 Intelligence field is where the Marine Corps organizes its analysis, collection management, imagery intelligence, geospatial intelligence, and human-intelligence work. The core MOSs in OccFld 02 each serve a specific function in the intelligence production and collection cycle.

0231 Intelligence Specialist is the all-source analyst path. 0231s collect, process, and analyze information from multiple sources to produce intelligence products that support Marine commanders. They write and brief intelligence assessments, maintain the situational awareness picture, and integrate reporting from imagery, signals, and human sources into coherent analysis. This is the broadest entry point into the 02 field and the right starting MOS for applicants who want analyst work without locking into a highly specialized technical track early.

0241 Imagery Intelligence Specialist focuses on imagery exploitation. 0241s analyze satellite, aerial, and other imagery to identify targets, assess battle damage, map terrain features, and answer intelligence questions through visual and spectral analysis. The work is technical but relies on visual interpretation skills and geospatial reasoning rather than programming or network operations.

0261 Geospatial Intelligence Specialist focuses on the geographic and mapping dimensions of intelligence. 0261s produce geospatial products, terrain analysis, and mapping support for operational planning and intelligence dissemination.

0211 Counterintelligence/HUMINT Specialist is the human-source and threat-investigation path. 0211 is typically a lateral-move MOS for Marines who have demonstrated reliability and maturity in another MOS before being selected for the CI/HUMINT pipeline. It is not typically accessible through a standard entry-level recruit contract.

The 02 field suits Marines who are drawn to analysis, briefing, research, and the intellectual challenge of turning raw information into decisions that commanders can act on. It rewards written communication, attention to detail, and the ability to integrate conflicting information into a coherent picture.

Training pipeline and clearance for OccFld 02

Marines designated for 0231 attend intelligence training at Dam Neck, Virginia, covering intelligence fundamentals, all-source analysis methods, collection management, and reporting standards. Pipeline length varies by specific MOS. The 0211 path requires additional CI/HUMINT course training after the formal lateral-move selection process is complete.

All 02-field MOSs require security clearance processing. Most 02 assignments require at minimum a Top Secret clearance with Sensitive Compartmented Information access. The investigation and adjudication process begins at contract signing and must complete before the Marine can access the classified systems and materials their MOS requires.

Civilian transfer from OccFld 02

0231 all-source analysts often transition to federal agency analyst positions, defense intelligence contractor support roles, or private-sector research and analysis positions. The structured analytical methodology, report-writing discipline, and classification experience are directly applicable.

0241 imagery specialists transition to geospatial analysis, imagery exploitation, and remote sensing roles with government agencies and commercial satellite imagery companies. The commercial earth-observation market has grown considerably, creating non-government pathways for imagery-trained veterans alongside the traditional government and contractor route.

0261 geospatial specialists transition to GIS analyst positions, spatial data roles in commercial and government contexts, and urban planning or environmental analysis positions that apply geospatial skills in non-intelligence settings.

0211 CI/HUMINT specialists often transfer through law enforcement, federal investigations, security program management, and corporate intelligence roles that value interview skills, source-handling discipline, and threat-assessment capability.

OccFld 17 Information Maneuver: cyber and influence work

OccFld 17 contains three MOS paths: 1721 Cyberspace Warfare Operator, 1751 Influence Specialist, and 1732 Civil Affairs Specialist.

1721 is the cyber operations path. 1721 operators conduct offensive and defensive cyberspace operations, working against adversary networks on the offensive side and protecting Marine network infrastructure on the defensive side. The MOS requires competitive selection, clearance, and a longer training pipeline than many enlisted paths. It is the right answer for applicants who want direct cyber operations work rather than general communications or network support.

1751 Influence Specialists operate in the information environment through messaging, audience analysis, and influence activities. The mission is distinct from cyber operations even though both sit in OccFld 17. Civilians with backgrounds in social science, communications, or behavioral research often find 1751 more intuitive than the 1721 technical track.

1732 Civil Affairs Specialists manage civil-military relationships in the operational area. Civil affairs work is part of the information-maneuver concept because civil conditions shape the environment Marines operate within. It is a strong fit for Marines with interest in international affairs, stability operations, and the political dimensions of conflict.

OccFld 26 SIGINT/EW/Cyberspace Operations: signals and electromagnetic work

OccFld 26 is where the most technical signal and electromagnetic work is organized. The 26 field is the right starting point for applicants interested in signals intelligence, electronic warfare, or ISR systems rather than the analysis or cyber operations dimensions of the intelligence space.

2621 Communications Intelligence/Electronic Warfare Operators collect and analyze adversary communications signals in the electromagnetic environment. The work involves operating specialized collection equipment, processing intercepts, and producing intelligence reporting from raw communications data.

2631 Electronic Intelligence/Electronic Warfare Analysts analyze radar and electronic emitter signals, characterize the adversary’s electronic order of battle, and support jamming and other EW effects. The mission focuses on non-communications emitters and electromagnetic spectrum management.

2651 ISR Systems Engineers operate and maintain ISR platforms and collection systems that feed the SIGINT and EW mission. This MOS has the most systems-engineering character of the three, with significant responsibility for keeping complex technical platforms operational in field environments.

The 26 field suits applicants who want to work with signals, electromagnetic systems, and technical collection platforms. Marines drawn to technical problem-solving, precision equipment operation, and classified analytical environments tend to find the 26 field mission set more satisfying than the analysis-and-briefing orientation of 02.

Clearance tiers across all three fields

All three fields trend toward security clearance requirements. OccFld 02 and OccFld 26 generally require Top Secret/SCI for operational assignments. OccFld 17 paths including 1721 also require Top Secret/SCI. Some 02-field assignments involving CI work may require a polygraph examination as part of the access determination.

Marines considering any of these three fields should honestly assess their clearance eligibility before committing to an MOS that depends on it. The investigation reviews finances, drug history, foreign contacts, and other factors. Applicants with known history in any of these areas should discuss the situation with a recruiter before building a career plan around clearance-dependent MOS selection.

The clearance as a career asset

The clearance has civilian market value, but only if the Marine maintains it through continued qualifying activity. A clearance that lapses loses its market value quickly, and reactivating a lapsed investigation is a lengthy process.

Marines in 02, 17, and 26 who transition to civilian employment benefit most from maintaining clearance activity through cleared contracting roles, reserve component service in cleared MOSs, or federal employment that continues the investigation cycle. Marines who move into uncleared roles after separation should understand that their clearance will effectively lapse without continued cleared employment, even if it was never formally revoked.

This dynamic makes post-service career planning for these fields different from planning for non-cleared MOSs. The civilian path that best preserves the clearance value is the one that keeps the Marine in the cleared labor market rather than accepting the first available non-cleared position.

Pay context and the clearance premium

Base pay for enlisted Marines in all three fields follows the standard grade-and-years-of-service table. An E-4 with two years of service earns $3,303.00 per month. Housing allowance adds a substantial monthly figure on top for Marines living off-base, varying by installation, grade, and dependency status.

The real financial differentiation for OccFld 02, 17, and 26 Marines comes from the clearance-linked civilian market at separation. A Marine who separates with a current TS/SCI investigation and documented operational intelligence or cyber experience earns a meaningful premium in the cleared contracting market compared to what the same Marine’s base pay at separation would suggest. Defense contractors and intelligence community agencies pay for access, reliability, and documented operational experience in classified environments.

Under the Blended Retirement System, Marines in competitive-retention MOSs who re-enlist past the eight-year mark may qualify for continuation pay above the 2.5x monthly basic pay minimum. This reflects the Marine Corps’ retention challenge in technical and intelligence MOSs where trained personnel face consistent competing offers from the civilian cleared market.

Marines in these fields who are making re-enlistment decisions at the 4-6 year mark should compare their specific continuation pay offer, if applicable, against their projected post-service compensation in the cleared market. The decision is not purely financial, but the financial picture is real and worth modeling with accurate numbers rather than general assumptions.

Selecting the right field

The matching process is faster when the applicant focuses on mission type.

If the work that sounds interesting is analysis, briefing, imagery, source handling, and turning raw information into decisions: OccFld 02.

If the work is network operations, cyber attack and defense, or information-environment influence: OccFld 17.

If the work is signals collection, electromagnetic exploitation, and ISR systems: OccFld 26.

The secondary filter is the entry pattern. The 0231 and 26-field paths are accessible through standard recruit contracts. The 0211 CI/HUMINT path typically requires prior service and a formal lateral-move selection process. The 1721 path requires competitive selection at the initial accession stage. Knowing which entry pattern is available at your current career stage sharpens the field comparison considerably.

ASVAB considerations

All three fields reward strong GT performance. The GT composite (VE plus AR) reflects verbal and quantitative reasoning abilities that analysis, cyber operations, and signals work all require. Marines who want to be competitive in these fields should prioritize GT performance in their ASVAB preparation.

The EL composite (GS plus AR plus MK plus EI) may also factor in for electronics-heavy 26-field MOSs. Marines targeting 2631 or 2651 specifically should confirm current ASVAB composite requirements with a recruiter, as the technical depth of those paths may have specific EL minimums that differ from the general field floor.
