US Marine Corps Creates 0315 Scout: A Dedicated Reconnaissance Career Field for Every Infantry Battalion
Technical Summary
The United States Marine Corps has created a new primary military occupational specialty (PMOS), 0315 Scout, with effect from 1 October 2026. Marine Administrative Message (MARADMIN) 296/26, released on 26 June 2026 and publicised by the service on 30 June, adds the specialty to the Fiscal Year (FY) 2027 MOS Manual as an out-of-cycle change. The decision converts scout duty from an additional qualification held by infantry Marines into a deliberately managed career field spanning private to sergeant, sponsored by the Deputy Commandant for Plans, Policies, and Operations (PP&O). Lieutenant General Jay M. Bargeron, who holds that post, called the change “a critical step in the modernization of our infantry battalions.”
Each infantry battalion will field a 26-Marine Scout Platoon, and the light armored reconnaissance (LAR) battalions gain dedicated Scout Teams. The platoons carry advanced optics, communications suites, sensors and unmanned aircraft systems (UAS) for ground reconnaissance, surveillance and battlespace shaping through assured long-range communications. Every scout team includes a Joint Fires Observer (JFO) trained to coordinate and control surface-to-surface and air-delivered fires. Individual scouts are armed with the M4 service rifle, the M320 grenade launcher and the M27 Infantry Automatic Rifle (IAR).
These Scouts will be our eyes and ears, extending our sensing capabilities and enabling commanders to make faster, more effective decisions to win our nation’s battles. Lt Gen Jay M. Bargeron, Deputy Commandant for Plans, Policies, and Operations · US Marine Corps release, 30 June 2026
Routes Into the New Specialty
MARADMIN 296/26 sets the aptitude floor at a general technical (GT) score of 95, or an electronics (EL) or clerical (CL) composite of 100, and defines four routes into the specialty, summarised below. Commands must submit conversion lists for batch execution no later than 1 November 2026.
| Entry route | Training required | Notes |
|---|---|---|
| Initial accession | Infantry Common Core Course and Infantry Rifleman Course, then the Ground Reconnaissance Course (M10RAN2) | Steady-state production begins in FY 2027; the FY 2026 pilot cohort earns the PMOS on course completion |
| Lateral move, prior infantry MOS (0311, 0313, 0331, 0341, 0352) | Ground Reconnaissance Course only | Foundation infantry courses waived |
| Holders of additional MOS 0317 Scout Sniper | None | Immediate conversion, no further training |
| Basic Scout Course graduates (E5 and below, 03XX, excluding 0321) | None | Final legacy courses convene 13 July and 3 September 2026 at School of Infantry East, with travel centrally funded |
The Ground Reconnaissance Course anchoring the pipeline is itself new. Its first class reported on 27 April 2026 under a wider overhaul that replaced the 12-week Basic Reconnaissance Course with two successive schools, covering land navigation, water survival, surveillance and supporting arms in the ground phase. Training Command has said the course formalises scout training for the infantry and LAR battalions. Candidates for the separate 0321 Reconnaissance field continue to the Amphibious Reconnaissance Course; the 0315 pipeline stops at the ground phase.
Analysis of Effects
The design places fires expertise at the lowest practical echelon. With a JFO in every team, a battalion gains multiple dispersed observers able to call for and adjust artillery, mortar and naval surface fires, and to pass targeting data in support of air-delivered attack. Joint doctrine still separates the observer from the joint terminal attack controller (JTAC), who retains terminal attack control of aircraft, yet the effect is a platoon that can find targets, classify them and route them to whichever delivery system the battalion or its supporting arms hold ready. The service describes the formation as a multidomain sensing platoon; in fires terms it is equally a demand generator for precision munitions, loitering effects and small UAS.
The announcement completes a structural evolution that began in March 2023, when the Commandant approved the 26-Marine Scout Platoon and simultaneously divested the scout sniper platoons. Precision marksmanship stayed in the rifle companies with designated marksmen, the 0322 Reconnaissance Sniper track absorbed the deep-reconnaissance sniping role, and the 0317 Scout Sniper MOS ceased to be awarded at the end of FY 2023. Since then scout platoons have been manned by riflemen holding 0315 as an additional qualification. Live-force experimentation under the Infantry Battalion Experimentation campaign, validated by the Marine Corps Warfighting Laboratory, convinced the service that ad hoc manning could not sustain the skill base, and a Force Structure Decision Memorandum signed on 24 June 2026 directed the permanent career field.
From the 95th Rifles to the 0315
Armies periodically re-learn the value of a professional scout class. Britain raised its Corps of Riflemen in 1800, armed it with the rifled Baker flintlock and trained it to skirmish ahead of the line, screening the main body and reporting what it saw. That green-jacketed archetype, kept alive in popular fiction by Bernard Cornwell’s Sharpe novels, worked by fieldcraft, marksmanship and initiative. The 0315 Scout swaps the Baker rifle for electro-optics, assured communications and unmanned aircraft, and adds a fires observer to every team. The tactical logic is unchanged: put disciplined eyes forward, keep them alive, and let the commander act on what they report.
Personnel and Safety Considerations
For career managers the change creates a development path that the additional-MOS model never offered. Noncommissioned officers serve as scouts, assistant scout team leaders and scout team leaders, and the new PMOS now counts towards the 0369 Infantry Unit Leader progression and the 0913 Marine Combat Instructor billet. Retention falls under the FY 2027 enlisted retention campaign. Safety and competence questions centre on fires integration: teams flying UAS while adjusting indirect fire must manage airspace coordination measures in real time, and JFO qualification carries currency requirements that battalions will need to resource deliberately rather than opportunistically.
Data Gaps
Open sources do not state the internal team organisation of the 26-Marine platoon, the number or manning of LAR Scout Teams, the specific optics, radio and UAS types to be fielded, or the steady-state inventory target for the specialty. Published detail on Ground Reconnaissance Course duration and annual throughput remains thin. Claims in circulation about a fixed team count within the platoon are not confirmed by the Marine Corps and are excluded from this assessment. All load-bearing facts above trace to MARADMIN 296/26 or the service press release, and confidence in them is high.
Key Questions
What is the new USMC 0315 Scout MOS?
PMOS 0315 Scout is a new US Marine Corps primary military occupational specialty, effective 1 October 2026, created by MARADMIN 296/26. It mans a 26-Marine Scout Platoon in each infantry battalion and Scout Teams in light armored reconnaissance battalions, providing dedicated ground reconnaissance, surveillance and battlespace shaping.
How does a Marine become an 0315 Scout?
New entrants complete the Infantry Common Core and Infantry Rifleman Courses and then the Ground Reconnaissance Course, with a GT score of 95 or higher. Marines already holding an infantry MOS attend only the reconnaissance course, while 0317 Scout Snipers and Basic Scout Course graduates convert immediately without further training.
How do 0315 Scouts differ from Reconnaissance Marines and Scout Snipers?
Scouts belong to the infantry battalion and operate near its forward edge, cueing fires through a Joint Fires Observer in every team. Reconnaissance Marines (0321) work deeper in the battlespace for higher commands. The 0317 Scout Sniper specialty stopped being awarded in 2023; its holders may convert directly to 0315.
