The 3M Combat Arms Earplug litigation became one of the largest mass tort cases in American legal history. Over 340,000 veterans and active-duty service members filed claims alleging that the dual-ended earplugs — issued by the military from around 2003 to 2015 — were defective and caused hearing loss, tinnitus, and related auditory injuries. After years of federal court battles across the Multi-District Litigation (MDL) in the Northern District of Florida, 3M agreed in August 2023 to a $6.01 billion settlement structured through a bankruptcy reorganization of its Aearo Technologies subsidiary. By 2025, payments have been flowing. This article explains exactly how much veterans are receiving, how the tier system works, what documentation was required, and what a realistic net payout looks like after fees and liens.
The $6 Billion Settlement: What It Actually Means
The headline number — $6.01 billion — comes from 3M's August 2023 settlement agreement resolving claims related to the dual-ended Combat Arms Earplugs Version 2 (CAEv2). The settlement was structured through Aearo Technologies, 3M's former subsidiary that originally manufactured the earplug, which filed for Chapter 11 bankruptcy protection in July 2022 in an attempt to consolidate all litigation into a single forum and cap total liability.
The bankruptcy strategy was initially rejected by the MDL court in Florida, which ruled that Aearo's bankruptcy filing could not stay claims against 3M itself. After years of parallel proceedings, 3M ultimately negotiated a global settlement that would fund a Bankruptcy Benefit Fund (BBF) — a structured trust designed to pay qualifying claimants based on the severity of their injuries and the strength of their documentation.
The $6.01 billion is not a per-person guarantee. It is the total pool of money allocated across all qualified registrants. The amount each veteran actually receives depends entirely on their assigned tier and individual scoring under the BBF point system. The fund is administered by an independent trustee appointed through the bankruptcy court, and distributions follow a structured wave schedule that began in late 2023 and continues into 2025 and beyond.
To put the scale in context: if the full $6 billion were divided equally among all 340,000 registered claimants, each person would receive approximately $17,600. But the fund does not work that way. High-severity cases receive multiples of that figure, while low-severity cases with weak documentation receive far less. Understanding the tier system is therefore the most important factor in predicting your payout.
The BBF Tier System: How Tiers Are Assigned by Points
The Bankruptcy Benefit Fund evaluates each registered claimant through a point-scoring matrix that translates medical evidence, service history, and documentation quality into a numerical score. That score determines tier placement, and the tier determines the base settlement amount. There are five tiers — A through E — with Tier A representing the lowest severity and Tier E the highest.
The scoring system awards points across six primary categories:
- Audiometric evidence: Audiograms showing documented hearing threshold shifts are the single most important factor. A pure-tone average (PTA) shift of 25 dB or greater in speech frequencies (500 Hz, 1000 Hz, 2000 Hz, 3000 Hz) scores the most points. Bilateral (both-ear) losses score higher than unilateral losses.
- Tinnitus diagnosis: A clinician-documented diagnosis of tinnitus adds points, with severity rating (mild, moderate, severe, catastrophic) affecting the total. Veterans with both significant hearing loss and severe tinnitus achieve the highest combined scores.
- Duration of earplug use: Points are awarded for the number of years a veteran used the Combat Arms Earplug during qualifying military service. Longer documented use produces a higher score.
- Noise exposure history: Military occupational specialty (MOS) codes associated with high-noise environments — infantry, aviation, artillery, armor, engineering — carry additional points reflecting presumed exposure intensity.
- Corroborating medical records: Availability of military medical records (EPTS exams, separation physicals, in-service audiograms) that show pre-service baseline hearing levels versus post-service degradation strengthens the score substantially.
- Documentation completeness: Claims supported by DD-214, service records, buddy statements, and employment records demonstrating ongoing occupational noise exposure after service also receive points.
Average Payouts by Hearing Condition and Tier
Based on public court filings, attorney disclosures from MDL proceedings, and reporting from veterans advocacy groups, the following ranges reflect what qualifying claimants in each tier have received or are projected to receive as Wave disbursements continue:
| Tier | Qualifying Condition | Gross Settlement Range | Est. Net After 40% Fee |
|---|---|---|---|
| Tier A | Mild hearing loss, limited documentation, minimal tinnitus | $5,000 – $15,000 | $3,000 – $9,000 |
| Tier B | Moderate hearing loss or documented tinnitus, some corroborating records | $15,000 – $75,000 | $9,000 – $45,000 |
| Tier C | Severe hearing loss and/or tinnitus, strong audiometric and service records | $75,000 – $175,000 | $45,000 – $105,000 |
| Tier D | Profound bilateral hearing loss, documented functional impairment, complete records package | $175,000 – $300,000 | $105,000 – $180,000 |
| Tier E | Near-total or total hearing loss, catastrophic tinnitus, maximum documentation | $300,000 – $350,000+ | $180,000 – $210,000+ |
These ranges are not official government schedules. The BBF plan does not publicly publish a fixed per-tier dollar amount the way the Camp Lejeune Elective Option does. Instead, each eligible claimant's gross payment is calculated by multiplying their individual point score by a base rate per point that the BBF trustee adjusts periodically depending on total fund assets and the aggregate point scores of all qualified registrants. This means early registrants with complete records who maximized their point scores often achieved better per-point rates than late-filing claimants.
Timeline of Payments: Wave 1 Through Wave 4
The BBF began disbursing payments on a wave schedule following court approval of the bankruptcy reorganization plan in early 2023. Understanding where each wave stood helps veterans gauge when to expect payment.
Wave 1 (Late 2023): The inaugural distribution prioritized claimants with Tier C, D, and E designations who had submitted complete documentation packages during the original MDL registration period. Approximately 12,000–15,000 veterans received Wave 1 payments. Gross amounts in this wave skewed toward higher-severity cases, with many Tier D and E claimants receiving payments in the $150,000–$300,000 range before fees.
Wave 2 (Early–Mid 2024): Wave 2 expanded the pool to include Tier B claimants who had resolved outstanding documentation deficiencies and cleared Medicare/Medicaid lien negotiations. An estimated 40,000–50,000 claimants received Wave 2 payments. Gross amounts in this wave concentrated in the $20,000–$90,000 range for most recipients.
Wave 3 (Late 2024 – Early 2025): Wave 3 addressed a large volume of mid-tier claimants who registered closer to the original MDL deadline and had taken longer to compile full records packages. Approximately 60,000–80,000 claimants were processed in Wave 3. This wave also included a supplemental distribution for certain Tier A claimants who had upgraded documentation after initial filing.
Wave 4 (Mid-2025 – Ongoing): As of the writing of this article, Wave 4 is in active disbursement. It covers remaining registered claimants whose lien negotiations, documentation reviews, and tier appeals are resolving. The BBF trustee has indicated that processing continues, with final distributions for the lowest-severity Tier A cases expected to complete by late 2025 or early 2026.
Veterans who registered but have not yet received payment should contact their attorney or the BBF claims administrator to check their position in the queue. Delays most commonly stem from unresolved Medicare liens, missing audiogram records, or pending tier appeals.
What Documentation You Needed to Register
Registration quality was the single biggest variable separating high-paying tier placements from low ones. Veterans who assembled a comprehensive records package before submitting their claim consistently outperformed those who submitted incomplete filings. The core documentation requirements included:
- DD-214: Certificate of Release or Discharge from Active Duty confirming the service period and character of discharge. This establishes eligibility and is the foundational document.
- Military occupational specialty records: Documents confirming the MOS or rate, particularly for high-noise specialties. Training certificates, unit assignment records, and deployment orders all help.
- Service medical records: Entrance physicals showing pre-service audiometric baselines and exit physicals or separation audiograms showing post-service thresholds. The shift between these two data points is the core medical evidence in most claims.
- Post-service audiograms: VA audiology evaluations and private audiologist records taken within a reasonable period after discharge. Multiple audiograms taken over time demonstrating progressive loss are the strongest possible evidence.
- Tinnitus documentation: Clinician notes, VA compensation and pension (C&P) examination reports, and medical diagnoses specifically recording tinnitus with severity classification.
- Proof of earplug issuance: Unit supply records, deployment manifests, or buddy declarations attesting to Combat Arms Earplug distribution and use during the qualifying service period. 3M earplugs were standard issue for many units between 2003 and 2015, and unit records often confirm mass issuance.
- VA disability rating letter: If already service-connected for hearing loss or tinnitus, the VA rating decision is powerful corroborating evidence and helped establish severity for tier purposes.
Why Some Veterans Received More Than Others
Variation in settlement amounts within the same tier reflects several factors beyond the base scoring matrix. The most significant drivers of above-average payouts include:
Severity and recency of the hearing loss progression. Veterans who could document an audiometric shift of 40 dB or more in speech frequencies — particularly with objective supporting evidence like word recognition score degradation — scored substantially higher than veterans with equivalent subjective complaints but less audiometric documentation.
Bilateral versus unilateral loss. Veterans with hearing loss in both ears received significantly more points than those with single-ear loss, reflecting the greater functional impact of bilateral auditory impairment on daily life, employment, and communication.
Combined hearing loss and tinnitus. Veterans who had both documented hearing loss and a severe or catastrophic tinnitus diagnosis stacked points from both categories. The combination of Tier D-level hearing loss with severe tinnitus could push a claimant into Tier E territory under the point system.
Documentation completeness and early registration. The MDL court and the BBF trustee gave considerable weight to the quality and completeness of supporting records. Veterans who registered early with a full package — particularly those whose attorneys had experience organizing mass tort medical evidence — received faster tier confirmations and better per-point base rates in earlier waves.
VA service connection status. Already being service-connected for hearing loss or tinnitus at the time of registration was a significant practical advantage. The VA's adjudication process requires substantial evidence, and a favorable rating decision served as pre-validated corroboration for BBF purposes.
Occupation after service. Veterans who worked in low-noise civilian environments after discharge benefited from the cleaner causal chain linking military noise exposure to hearing damage. Those who worked in construction, manufacturing, or other high-noise industries post-service had to rebut arguments that civilian noise contributed to their hearing loss — a complication that sometimes reduced point scores or required additional expert documentation.
VA Benefits on Top of the Settlement
One of the most important facts for veterans to understand is that the 3M Combat Arms Earplug settlement does not offset or replace VA disability compensation for hearing loss and tinnitus. These are entirely separate legal remedies arising from different legal frameworks, and veterans are entitled to receive both.
Hearing loss is the single most prevalent service-connected disability in the VA system, with over 1.3 million veterans currently receiving monthly compensation. Tinnitus is the most commonly claimed condition overall. Veterans rated for hearing loss typically receive 0%–100% disability ratings, though the practical rating for isolated bilateral hearing loss under the VA's Diagnostic Code 6100 rarely exceeds 30% unless loss is severe. Monthly compensation at 10% disability (2025 rates) is approximately $175; at 30%, approximately $525; at 100%, approximately $3,750.
Veterans who have not yet filed VA claims for hearing loss or tinnitus should do so regardless of whether they have received or expect a 3M settlement. The two systems run in parallel. Filing a VA claim does not jeopardize the settlement, and the settlement does not reduce your monthly VA check.
However, if Medicare or Medicaid paid for hearing-related medical care during the period of litigation, federal law requires reimbursement from settlement proceeds. These are called conditional payment liens, and the Centers for Medicare and Medicaid Services (CMS) has asserted them in many 3M cases. Experienced mass tort attorneys negotiate these liens down — often by 50%–75% — before final distribution. Unrepresented claimants who did not negotiate their Medicare liens have sometimes seen larger-than-expected deductions from gross settlement amounts.
Attorney Fees and Net Payout
Most veterans in the 3M MDL were represented under contingency fee agreements. The standard contingency fee in the MDL was approximately 40% of the gross recovery, inclusive of case expenses. This is higher than the 33% standard in many personal injury cases, reflecting the complexity and duration of mass tort litigation and the MDL structure's co-counsel sharing arrangements.
The practical impact on net payout is significant. A veteran who receives a gross settlement of $100,000 will take home approximately $60,000 before lien deductions. If Medicare paid $8,000 in related medical costs and the attorney successfully negotiated that lien down to $3,000, the veteran's net is approximately $57,000.
Some veterans have questioned whether the 40% fee was appropriate given that the MDL ultimately settled rather than going to verdict. In mass tort MDL settlements, fee structures are typically reviewed and approved by the MDL judge as part of the global settlement order, providing a layer of judicial oversight. The 3M MDL court in Pensacola reviewed the fee structure as part of the bankruptcy reorganization approval process.
Veterans who were unrepresented and filed pro se claims should be aware that the BBF plan does include provisions for unrepresented claimants, but navigating the documentation, scoring, and lien resolution process without counsel has generally produced less favorable outcomes — both in tier placement and in lien negotiation.

A Final Note for Veterans Still Waiting
If you served in the U.S. military between 2003 and 2015, used Combat Arms Earplugs during training or deployment, and have experienced hearing loss or tinnitus since leaving service, and you have not yet registered with the BBF, you may still have options — but time is a critical variable. The MDL registration deadlines have passed for the main claim pool, but the bankruptcy trust process has provisions for certain late-filed claims under specific circumstances. Consulting an attorney who practices in the 3M MDL space is the only way to determine whether any remaining path exists for unregistered claimants.
For veterans already registered and awaiting Wave 4 or a tier appeal decision: document everything, respond promptly to any requests from the BBF administrator or your attorney, ensure your Medicare/Medicaid lien resolution is actively progressing, and keep your VA hearing records current. A current VA C&P examination — even if you already have a rating — can provide updated audiometric data that strengthens a tier upgrade appeal.
The 3M litigation has been long, adversarial, and complex. But the $6 billion fund represents a genuine acknowledgment that hundreds of thousands of Americans who served their country were given defective hearing protection — and that the company responsible bears a financial obligation to those injured as a result.
