11B Infantryman VA Disability Claim Guide
Army 11B service is one of the most physically loaded occupations in the U.S. military: sustained load carriage, repeated airborne or mounted movement, crew-served weapons fire, and — for post-9/11 soldiers — deployment environments with blast and airborne particulate exposure. That history can help explain what happened to a body over an enlistment, and it can corroborate an in-service event or exposure. It does not, by itself, establish that any particular disability exists or that a current condition was caused by service. This guide covers what the 11B record tends to show, which documents corroborate it, how VA evaluates these claims, and why infantry claims are frequently denied even when VA accepts the exposure.
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 11B duty actually involved
Infantry duty is built around moving and fighting on foot with equipment. Field time is dominated by foot movement under load, repeated ingress and egress from vehicles or aircraft, digging and constructing fighting positions, and live-fire training with rifles, machine guns, grenade launchers, and shoulder-fired weapons. Body armor plus a combat load routinely places sustained axial and shoulder load on the spine and lower extremities, and published Army and allied-military studies document musculoskeletal injury rates tied to load carriage and repetitive marching in infantry populations. Which of these applied to any individual soldier depends on unit, assignment, era, and deployment history.
- Foot movement under a fighting load and rucksack, frequently over uneven terrain
- Live-fire training and qualification with rifles, machine guns, and grenade launchers
- Repetitive lifting and carrying of ammunition, water, radios, and crew-served weapon components
- Fighting-position construction, digging, and prolonged kneeling and prone work
- Airborne operations in airborne-coded assignments; vehicle mounting and dismounting in mechanized and Stryker units
- Field living conditions: sleep disruption, temperature extremes, and dust
- For post-9/11 service, deployment environments that may include blast events, convoy operations, and open-air burn-pit smoke

Era and assignment note: Duty content differs sharply by assignment. A light-infantry rifleman in an airborne battalion, a mechanized soldier in a Bradley section, and a Stryker infantryman carry different load, vibration, and noise profiles even under the same MOS.
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
Infantry duty is treated as a highly probable noise-exposure occupation in VA's adjudication guidance, because rifle, machine-gun, and grenade-launcher fire routinely exceed hearing-hazard thresholds even with hearing protection in use.
Records that corroborate it
- · Hearing-conservation audiograms (DD 2215 entrance / DD 2216 periodic) and DOEHRS-HC data
- · Weapons qualification and range records
- · Enrollment in a hearing-conservation program, which itself indicates a noise-hazardous duty assignment
What it does not establish: Accepted noise exposure does not establish a current hearing-loss disability for VA purposes, which is defined by the audiometric thresholds in 38 CFR § 3.385, and it does not by itself supply the medical link between service noise and a current diagnosis.
Physical demands and load carriage
Sustained load carriage, road marches, and repeated lifting are characteristic of the occupation and are documented in Army physical-demands literature.
Records that corroborate it
- · Evaluation report (NCOER) bullets describing road marches, air-assault or airborne operations, and field time
- · Temporary and permanent physical profiles (DA Form 3349)
- · Sick-call entries, physical-therapy referrals, and any MEB or LIMDU documentation
What it does not establish: Typical demands of the occupation are not proof that a specific joint was injured in service. A current diagnosis and evidence tying that diagnosis to service are generally still required.
Blast and trauma potential
Exposure to blast overpressure varies widely: shoulder-fired weapons, breaching charges, and IED events during deployment are recognized sources, but many 11B soldiers never experienced a blast event.
Records that corroborate it
- · Line-of-duty determinations and incident or after-action reports
- · Post-Deployment Health Assessment / Reassessment (DD 2796 / DD 2900) entries
- · Combat Infantryman Badge or Combat Action Badge on the DD-214
- · Contemporaneous treatment notes describing an altered-consciousness event
What it does not establish: A combat badge does not diagnose a traumatic brain injury, and a blast event does not establish residual disability without current clinical findings.
Deployment-dependent exposures
Location and dates control this entirely. Service on or near an installation with an open burn pit during covered periods may bring a claim within the PACT Act presumptive framework; service elsewhere does not.
Records that corroborate it
- · Deployment orders, travel vouchers, and the DD-214 remarks block
- · Unit deployment histories and mobilization orders
- · VA's Airborne Hazards and Open Burn Pit Registry entry
What it does not establish: The MOS itself proves nothing about location. Presumptive status depends on the statutory location and time period plus a listed condition, not on the job title.
Combat and operational stressors
Infantry assignments carry an elevated likelihood of exposure to combat stressors during deployment, but exposure remains individual and must be described, not assumed.
Records that corroborate it
- · Combat badges, award citations, and unit after-action reports
- · VA Form 21-0781 stressor statement and buddy statements
- · Behavioral-health encounters during or after service
What it does not establish: A stressor is one element. A PTSD claim also requires a diagnosis meeting the DSM-5 criteria and a link between the stressor and the diagnosis, per 38 CFR § 3.304(f).
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 | Infantry weapons fire is a recognized hazardous-noise source and the occupation is treated as high-probability for noise exposure in VA's guidance. | A current report of persistent tinnitus, audiology examination, and a lay account of onset and continuity; audiograms showing a threshold shift help but are not required for tinnitus. |
| Hearing | Sensorineural hearing loss | Repeated impulse noise is associated with high-frequency sensorineural loss in occupational-health literature. | Audiometry meeting the 38 CFR § 3.385 disability thresholds, entrance and separation audiograms for comparison, and a medical opinion addressing the pattern of loss. |
| Lumbar spine | Lumbar strain, degenerative disc disease | Load carriage and repetitive lifting place cumulative axial load on the lumbar spine. | Current imaging and range-of-motion findings, in-service sick-call or profile records, and an opinion addressing cumulative loading rather than a single incident. |
| Knees | Patellofemoral pain, meniscal pathology, degenerative arthritis | Marching under load, repeated kneeling, and jumping from vehicles or aircraft are recognized mechanical stressors. | Current diagnosis with measured flexion and extension, evidence of instability if claimed, and documentation of in-service onset or continuity. |
| Ankles and feet | Ankle instability, plantar fasciitis, pes planus aggravation | Uneven-terrain movement under load is a documented mechanism for ankle sprain recurrence and plantar heel pain. | Treatment records, current examination findings, and — where a foot condition pre-existed service — evidence addressing aggravation beyond natural progression. |
| Mental health | PTSD, depressive and anxiety disorders | Combat and operational stressor exposure is more likely in infantry assignments, though it remains individual. | A diagnosis meeting DSM-5 criteria, 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 occupation, though not in every career. | Documentation of the event, contemporaneous or post-event symptoms, and current neurological or neuropsychological findings evaluated under the DC 8045 facets. |
| Respiratory | Asthma, rhinitis, sinusitis, and PACT Act presumptive conditions | Relevant only where deployment location and dates place the veteran within a covered exposure period. | Deployment documentation establishing location and dates, current pulmonary testing, and a diagnosis matching the presumptive list where one applies. |

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 11B claims.
Noise exposure conceded, service connection still denied for lack of nexus
This is the most common infantry denial. VA accepts that an 11B was exposed to hazardous noise, then relies on an audiologist's opinion that the current hearing loss is not related to service — often because entrance and separation audiograms both appeared normal. The Court has held that a normal separation audiogram does not by itself defeat a hearing-loss claim, so the quality of the examiner's rationale is usually the real issue.
No current diagnosis of the claimed joint condition
Pain alone was historically insufficient; a claim generally needs a diagnosed disability or, following Saunders v. Wilkie, pain that produces functional impairment. Claims describing symptoms without current clinical findings are routinely denied at this step.
The examiner leaned on an unremarkable separation examination
Many infantry soldiers did not report injuries to sick call. When an opinion rests mainly on the absence of in-service treatment and does not address the veteran's competent lay account of onset and continuity, the examination may be inadequate under Barr v. Nicholson.
Chronicity or continuity of symptoms not established
Long gaps between separation and first treatment invite a denial reasoning that the condition arose later. Lay statements, employer or family accounts, and early civilian treatment records address this directly.
Rating assigned does not match documented severity
Service connection is granted but the evaluation is based on a single range-of-motion measurement that does not capture flare-ups or repetitive-use loss, contrary to 38 CFR §§ 4.40, 4.45 and the Court's decision in Correia v. McDonald.
Exposure occurred, but the claimed disease is not linked to it
A deployment may be documented while the claimed condition is neither on the applicable presumptive list nor supported by a medical opinion connecting it to the specific exposure.
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.
11B claim questions
Does being an 11B automatically qualify me for tinnitus benefits?
No. Infantry service supports the in-service noise-exposure element, and VA's adjudication guidance treats infantry as a high-probability noise occupation. A grant still requires a current tinnitus diagnosis or competent report of persistent tinnitus and a medical link to service. VA can and does deny tinnitus claims where the audiologist attributes the tinnitus to another cause.
What if I never went to sick call for my knees or back?
That is common in infantry units and it is not automatically fatal to a claim. Your own account of when symptoms began is competent evidence, and buddy statements, evaluation bullets, profiles, and early post-service treatment records can fill the gap. An examination opinion that dismisses those accounts solely because sick call is silent may be inadequate.
Can VA deny hearing loss even after conceding I was exposed to weapons noise?
Yes. Exposure satisfies one element of service connection. VA also requires a current disability — for hearing loss, thresholds meeting 38 CFR § 3.385 — and a medical opinion linking the two. A denial after a conceded exposure usually turns on the nexus opinion or the audiometric thresholds, which is exactly what a post-decision review examines.
Does my MOS prove I was exposed to burn pits?
No. Burn-pit and other airborne-hazard exposure depends on where and when you served, not on your job code. Deployment orders, the DD-214 remarks, and unit records establish location and dates; the PACT Act presumptions then depend on those facts plus a listed condition.
I held several MOSs — which one matters?
All of them. The personnel record shows every MOS held and the dates, and the exposure argument can draw on any assignment. A later reclassification does not erase earlier infantry duty, and an earlier one does not limit a claim based on later work.
Can National Guard or Reserve infantry duty support service connection?
It can, but the duty status matters. Injuries incurred or aggravated during active duty for training generally qualify, while inactive duty for training is more limited — typically injuries, and certain cardiovascular events. Retirement points statements and orders establish the status of the period in question.
What records actually show what I did as an infantryman?
The DD-214 for the primary specialty, badges, and deployments; the enlisted record brief for every assignment; NCOERs for narrative descriptions of what the job involved day to day; profiles and sick-call entries for in-service limitations; and hearing-conservation audiograms for noise exposure.
