0311 Rifleman VA Disability Claim Guide
The 0311 Rifleman MOS is the core of the Marine infantry battalion — the Marine who patrols, occupies fighting positions, and closes with the enemy on foot. A fitness report or Basic Training Record documenting 0311 service can help corroborate an in-service event or exposure, such as hazardous noise or a documented combat incident. It cannot, by itself, establish a current diagnosis or a medical link between service and a disability claimed today. This guide covers the duties, the exposures that vary most by unit and deployment, the records that corroborate them, and why VA still denies infantry claims after conceding exposure occurred.
Educational only. A military occupation is not presumptive evidence and does not establish service connection, a diagnosis, or a rating. Last updated 2026-09-06.
What 0311 duty actually involved
Rifleman duty centers on dismounted infantry movement: humping a fighting load or full deployment pack over distance, occupying and improving fighting positions, and employing the M4 or M16 service rifle along with the M203/M320 grenade launcher in training and combat. Marines rotate through fireteam and squad positions, conduct mounted and dismounted patrols, and — in the post-9/11 era — frequently deployed to Iraq or Afghanistan where dismounted patrolling added IED and small-arms-contact risk. Garrison time includes weapons ranges, field exercises, and physical training built around load-bearing movement.
- Foot movement carrying a fighting load or full pack ("humping") over rough terrain, often for days at a time
- Live-fire qualification and training with the M4/M16 service rifle, M203/M320 grenade launcher, and hand grenades
- Occupying, digging, and improving fighting positions; prolonged kneeling and prone firing positions
- Mounted and dismounted patrolling, including urban and rural combat environments during deployment
- Repetitive lifting of ammunition cans, water, and squad-level gear
- Field living: sleep deprivation, weather extremes, dust, and — for post-9/11 deployments — proximity to burn pits
Also covers: 0300 (basic infantry MOS series entry point for 03xx assignments)
Era and assignment note: Load and operational tempo differ by era. Post-9/11 riflemen frequently carried heavier body armor and equipment sets on repeated Iraq and Afghanistan deployments than earlier-era Marines, and dismounted patrolling in Helmand or Anbar province added blast and heat exposure that a peacetime rifleman would not have.
What this occupation may help establish
Each item below supports the in-service event or exposure element only, and only when the veteran's own records back it up.
Hazardous noise
Rifle and grenade-launcher fire on ranges and in combat routinely exceeds hearing-hazard thresholds, and infantry MOSs are treated as high-probability noise occupations in VA's adjudication guidance.
Records that corroborate it
- · Hearing-conservation audiograms (DD 2215 entrance / DD 2216 periodic) and DOEHRS-HC records
- · Marine Corps Basic Training Record and MCTFS entries showing range and qualification periods
- · Fitness reports referencing weapons training or combat deployment
What it does not establish: Documented noise exposure supports the event element only. A current hearing-loss disability under 38 CFR § 3.385, or a current tinnitus complaint, and a medical link to service are still required.
Load carriage and physical demands
Sustained movement under a combat load is intrinsic to the rifleman MOS and is documented in Marine Corps physical-readiness and injury-surveillance literature.
Records that corroborate it
- · Fitness reports describing field exercises, deployments, and physical fitness test results
- · Sick call and physical therapy entries in the health record
- · Limited-duty (LIMDU) chits and any Physical Evaluation Board documentation
What it does not establish: That the MOS commonly involves heavy loads does not establish that a specific joint was injured in service; a current diagnosis and a nexus are still needed.
Blast and combat-trauma exposure
Blast exposure depends heavily on deployment and unit — IED encounters, breaching, and enemy contact occurred in some rifleman assignments and not others.
Records that corroborate it
- · Line-of-duty determinations, after-action reports, and Purple Heart or Combat Action Ribbon citations
- · Post-Deployment Health Assessment / Reassessment (DD 2796 / DD 2900) entries
- · Contemporaneous medical entries describing an altered-consciousness event
What it does not establish: A combat award does not diagnose a traumatic brain injury. Residual disability still requires current clinical findings tied to the event.
Deployment-dependent exposures
Service on or near installations with open burn pits or other airborne hazards during PACT Act–covered periods may bring a claim within the presumptive framework; service elsewhere does not.
Records that corroborate it
- · Deployment orders and unit deployment histories
- · DD-214 remarks block listing deployments and campaign credit
- · Airborne Hazards and Open Burn Pit Registry participation
What it does not establish: The 0311 MOS itself says nothing about where a Marine served. Presumptive status turns on documented location and dates, not the job title.
Combat and operational stress
Rifleman assignments carry an elevated likelihood of direct combat exposure during deployment, though this remains individual to the unit and deployment.
Records that corroborate it
- · Combat Action Ribbon, award citations, and unit command chronologies
- · VA Form 21-0781 stressor statement and buddy statements from fellow squad members
- · Behavioral-health treatment entries during or after service
What it does not establish: A documented stressor is one element of a PTSD claim. A diagnosis meeting DSM-5 criteria and a link between the stressor and the diagnosis, under 38 CFR § 3.304(f), are also required.
Conditions that commonly arise from these duties
This is not a list of conditions to claim. It is a record-driven view of why the occupation may be relevant and what evidence VA looks at. Only you and your treating providers can identify what you actually have.
| Body system | Condition | Why the occupation matters | Evidence VA weighs |
|---|---|---|---|
| Hearing | Tinnitus | Rifle and grenade-launcher fire is a recognized hazardous-noise source, and infantry MOSs are treated as high-probability for noise exposure. | A current report of persistent tinnitus and a lay account of onset and continuity; audiometric threshold shifts help but are not required for tinnitus. |
| Hearing | Sensorineural hearing loss | Cumulative impulse noise from small arms and grenade launchers is associated with high-frequency hearing loss. | Audiometry meeting the 38 CFR § 3.385 thresholds, entrance/separation comparisons, and an opinion addressing the pattern of loss. |
| Lumbar spine | Lumbar strain and degenerative disc disease | Sustained load carriage places cumulative axial stress on the lumbar spine over an enlistment. | Current imaging and range-of-motion findings, in-service treatment or fitness-report references to field duty, and an opinion addressing cumulative loading. |
| Knees | Patellofemoral pain and degenerative arthritis | Marching under load and repeated kneeling in firing positions are recognized mechanical stressors on the knee. | Current diagnosis with measured range of motion, and documentation of in-service onset or continuity. |
| Ankles and feet | Ankle instability and plantar fasciitis | Movement over uneven terrain under load is a documented mechanism for recurrent ankle sprain and plantar heel pain. | Treatment records, current examination findings, and evidence of in-service onset where a foot condition did not preexist service. |
| Mental health | PTSD and depressive disorders | Direct combat exposure is more likely for riflemen who deployed to combat zones, though it remains individual. | A DSM-5 diagnosis, a described and where possible corroborated stressor, and treatment records showing occupational and social impairment. |
| Neurologic / TBI | TBI residuals and headaches | Blast and impact events occur in this MOS during combat deployments, though not in every career. | Documentation of the event, contemporaneous or later-reported symptoms, and current neurological findings evaluated under the DC 8045 facets. |
| Respiratory | Asthma, rhinitis, and PACT Act presumptive conditions | Relevant only where deployment location and dates place the Marine within a covered exposure period. | Deployment documentation establishing location and dates, current pulmonary testing, and a diagnosis on the presumptive list. |

Records that corroborate an occupational history
- DD-214 (Member 4 copy) — Primary specialty, awards, badges, and deployment remarks.
- Complete service treatment records — Sick-call entries, profiles, and separation examination.
- Personnel file (OMPF / enlisted record brief) — Every assignment, duty code, and date you served in it.
- Hearing-conservation audiograms (DD 2215 / DD 2216) — Baseline and periodic tests document noise-hazardous duty and threshold shifts.
- Current medical records with a diagnosis — A current disability is required regardless of what the service record shows.
- A medical opinion connecting the condition to service — Occupational history supports the opinion; it does not replace it.
- Lay and buddy statements — Fill gaps where nothing was written down at the time.
- Marine Corps Basic Training Record / MCTFS — Documents assignments, ranges, and qualification periods.
- Fitness reports (FitReps) — Narrative descriptions of deployments and field duty, similar to an NCOER.
- Combat Action Ribbon or Purple Heart citation — Corroborates a specific combat or blast event.
An occupational history supports the in-service event or exposure element of a claim. It is not presumptive evidence, it does not diagnose anything, and it does not establish service connection on its own.
Why these claims get denied
Denial language tells you which element of the claim failed. These are the patterns that recur in decisions on 0311 claims.
Noise exposure conceded, hearing claim denied for lack of nexus
VA frequently accepts that a rifleman was exposed to hazardous noise, then denies based on an audiologist's opinion that current loss is unrelated, often citing normal separation audiograms. A normal separation audiogram alone does not defeat a hearing claim, so the examiner's rationale is usually the real issue.
No current diagnosis for a claimed joint
Reports of chronic knee or back pain without a current diagnosed disability, or without functional-impairment evidence under Saunders v. Wilkie, are commonly denied at this threshold step.
Examiner relies on absence of sick-call visits
Many riflemen did not seek treatment in the field. An opinion built mainly on a quiet service treatment record, without addressing the Marine's lay account of onset and continuity, may be inadequate under Barr v. Nicholson.
Gap between separation and first treatment cited against the claim
A long delay before civilian treatment invites a finding that the condition developed later. Buddy statements and early post-service records help address this.
Rating understates severity documented at exam
A grant may still understate severity when the exam captures a single range-of-motion measurement without addressing flare-ups or repetitive-use loss under 38 CFR §§ 4.40, 4.45 and Correia v. McDonald.
Deployment established, but claimed condition isn't linked to the specific exposure
A combat deployment may be well documented while the claimed condition is neither presumptive nor supported by a medical opinion tying it to the exposure claimed.
VA accepted my exposure but still denied me
This is the most common outcome for occupational claims: VA concedes what the job involved, then denies on the medical link, the current-diagnosis element, or the rating criteria. A decision review looks at which element the decision actually turned on and what evidence would address it. Oakridge Claims focuses primarily on post-decision representation — Higher-Level Reviews, Supplemental Claims, and Board appeals — and also accepts initial claims and claims for increase based on case fit and current availability, at no fee for initial-claim representation.*
*No fee is charged for representation before VA issues an initial decision. If representation continues after an initial decision, fees may apply to eligible post-decision representation under a written VA-compliant fee agreement. See Fees for details.
0311 claim questions
Does being an 0311 automatically qualify me for tinnitus benefits?
No. Rifleman service supports the in-service noise-exposure element, since infantry MOSs are treated as high-probability noise occupations. A grant still requires a current tinnitus report and a medical link to service.
I never went to medical for my back or knees in the fleet — does that end my claim?
Not necessarily. Field infantry Marines often did not seek treatment. Your own account of onset, fitness reports describing field duty, and buddy statements can help fill that gap.
Can VA deny hearing loss even after admitting I was exposed to rifle and grenade-launcher noise?
Yes. Conceded exposure satisfies one element. A current disability meeting 38 CFR § 3.385 thresholds and a medical opinion linking it to service are also required.
Does deploying to Iraq or Afghanistan prove I was exposed to burn pits?
No. Exposure depends on the specific installation, location, and dates, not the deployment alone. Deployment orders and unit records establish those facts, which the PACT Act presumptions then apply to.
I held other MOSs before or after 0311 — does that matter?
Yes. Your Basic Training Record and MCTFS history show every MOS held. Exposure arguments can draw on any assignment documented in that record.
Can Reserve or inactive-duty infantry training support a claim?
It can, but duty status matters. Injuries during active duty for training are treated more favorably than those during inactive duty for training, which is generally limited to certain injuries and cardiac events. Orders and points statements establish the status.
What records best show what I did as a rifleman?
The DD-214 with MOS and deployments, the Basic Training Record/MCTFS history, fitness reports describing field duty, LIMDU chits, and hearing-conservation audiograms.
