Where the Combat Arms Litigation Stands in 2026
The 3M Combat Arms Earplug litigation was the largest MDL in U.S. history by plaintiff count — roughly 260,000 veterans alleging that 3M's dual-ended Combat Arms Version 2 (CAEv2) earplugs, standard-issue military hearing protection from 2003 through 2015, were defectively designed and inadequately protected service members from hearing loss and tinnitus.
Cases were consolidated in MDL 2885 in the Northern District of Florida under Judge M. Casey Rodgers. After a series of bellwether trials in 2019–2021 that produced meaningful plaintiff verdicts (and some defense wins), and after 3M's controversial 2022 attempt to shift liability to its subsidiary Aearo Technologies through bankruptcy — which was rejected by the U.S. Bankruptcy Court — the parties reached a global settlement.
The Injury
The two dominant claims:
- Tinnitus — persistent ringing, buzzing, or humming in the ears. The most common Combat Arms diagnosis. Ranges from mild to disabling.
- Sensorineural hearing loss — permanent hearing damage from noise exposure. Often bilateral. Frequently accompanied by tinnitus.
Both are compensable under the VA disability rating schedule and under the tort framework of the MDL. Cases where the veteran has documented both diagnoses typically qualify for higher tier assignments.
The Defect Theory
The plaintiffs' core theory: the CAEv2's dual-ended design (an open end for allowing communication and a closed end for maximum attenuation) had a flaw that caused the earplug to loosen imperceptibly during use, allowing damaging sound levels to reach the ear canal despite the wearer believing the earplug was properly seated. Internal 3M documents produced in litigation showed that engineers were aware of fit issues affecting protection during the mid-2000s. The plaintiffs argued that this internal knowledge, combined with the military-standard-issue distribution, made 3M liable for the resulting hearing damage.
The Settlement Framework
The August 2023 settlement contains several structural features worth understanding:
- Aggregate value: $6.01 billion. Combined settlement across substantially all claims.
- Tier-based individual allocations. Assignments based on injury severity, documented VA disability rating, service history, and specific medical records.
- Participation threshold. The deal required a high participation rate to close; that threshold was met in early 2024.
- Payment structure. A mix of cash and 3M stock, phased over multiple payment tranches to individual plaintiffs.
- Ongoing distribution timeline. Most individual plaintiffs are receiving payments in 2024–2026 as tier reviews complete and lien reconciliations resolve.
Where Individual Cases Stand in 2026
Most veteran plaintiffs are now in one of three positions:
- Received initial tranche. Plaintiffs with clean documentation who accepted early tier assignments received their first distribution in late 2024 or through 2025.
- Tier appeal in process. Plaintiffs whose tier assignments were lower than expected are pursuing appeals through the special master's process. These can add 6–12 months to the timeline.
- Lien reconciliation. VA benefits, Medicare, and health-insurance subrogation claims are being negotiated against the settlement. This is often the longest-tail component.

The Aearo Bankruptcy Story
In July 2022, 3M's subsidiary Aearo Technologies (which had manufactured the earplugs before 3M acquired the parent business) filed for Chapter 11 bankruptcy in an attempt to consolidate and cap 3M's Combat Arms liability. The theory paralleled Johnson & Johnson's LTL Management strategy in the talc litigation. The U.S. Bankruptcy Court rejected the maneuver in June 2023, finding that Aearo was not in genuine financial distress. The rejection cleared the path for the August 2023 global settlement.
Statute of Limitations
Combat Arms claims are largely resolved through the settlement. New claims from veterans who did not previously file face statute-of-limitations issues that vary by state, though discovery-rule analyses often preserve otherwise-stale claims. Veterans who believe they may qualify but did not previously file should consult counsel promptly.
Where Pre-Settlement Funding Fits
For plaintiffs whose tier assignments are confirmed and who are waiting on the final distribution tranche, pre-settlement funding is available and priced favorably — case value is largely defined at that stage, so underwriting can offer larger advances at lower rates. For plaintiffs still in the appeal process or whose lien reconciliation is complex, offer sizing is more conservative. See our companion pieces on funding for mass tort plaintiffs, on Roundup MDL 2741 for a comparable timeline, and on talc MDL 2738 for parallel context.
The Bottom Line
The 3M Combat Arms litigation demonstrates every dynamic of a modern mega-MDL: bellwether trials shaping value, a controversial bankruptcy maneuver rejected by the courts, and a global settlement structure that resolves the aggregate exposure while leaving individual distribution details to work through over multiple years. Veterans whose cases are moving through the tier-review and lien-reconciliation phases have a clear path to payment, and pre-settlement funding fits the wait.

Frequently asked questions
Substantially closed. The 2023 global settlement resolved essentially all claims, though a small number of opt-outs and post-settlement claims proceed individually.
Amounts vary widely by tier. Low-tier cases (mild tinnitus, no documented hearing loss) are typically in the low-five-figure range; high-tier cases (severe bilateral hearing loss with VA disability rating) can reach six figures.
Not strictly, but VA disability ratings for tinnitus and hearing loss are among the most powerful case-documentation tools in the tier structure.
The VA has certain reimbursement rights for related medical care. These are negotiated as part of the lien reconciliation phase.
Yes, particularly if your tier assignment is confirmed. Underwriting factors in the expected distribution timeline and any pending appeals.
The bellwether-trial phase, the Aearo bankruptcy filing, and the global-settlement structure negotiation each added time. This is typical for MDLs of this size.
Mixed verdicts — several substantial plaintiff wins, a smaller number of defense wins, and a couple of split verdicts. The mixed record ultimately drove both sides to negotiate rather than continue individual trials.
No. The CAEv2 was discontinued in 2015. Current-generation military hearing protection uses different designs.
