MM — Machinist's Mate

Includes Nuclear MM (MMN) — different radiation exposure profile.

Documented exposures for MM

Asbestos
Hazardous noise
JP-8 / jet fuel
Ionizing radiation

Exposure tags are drawn from 38 CFR §3.307, §3.309, §3.317, the PACT Act, and VA Public Health publications. Individual deployment history may broaden the list — use the personalizer below to layer service eras on top.

Presumptive claims this MOS may unlock (10)

Mesothelioma
VA M21-1 IV.ii.2.C
Long latency (20-40yr). Even decades after service, asbestos-exposed MOS = strong nexus.
Asbestos
Asbestosis
VA M21-1 IV.ii.2.C
Asbestos
Lung cancer (asbestos-related)
VA M21-1 IV.ii.2.C
Smoking history doesn't bar the claim if asbestos exposure documented.
Asbestos
Pleural plaques
VA M21-1 IV.ii.2.C
Asbestos
Tinnitus
DC 6260 · 38 CFR § 4.87 + §3.385
Flat 10% — easiest VA claim to win and the most commonly missed if vet doesn't realize it's ratable.
Hazardous noise
Guide →
Sensorineural Hearing Loss
DC 6100 · 38 CFR § 4.85 + §3.385
Even mild bilateral loss often rates 0% but service-connected status enables secondary tinnitus and protects against future degradation.
Hazardous noise
Respiratory conditions (PACT)
PACT Act §403
JP-8 / jet fuel
Chronic dermatitis
DC 7806 · M21-1 IV.ii.2.C
JP-8 / jet fuel
Liver / kidney symptoms
VA Public Health JP-8 page
JP-8 / jet fuel
Most cancers (broad presumption)
38 CFR §3.309(d)
Radiation-Risk Activities list at §3.309(d)(3) — atomic test participation, occupation of Hiroshima/Nagasaki, nuclear weapons handling.
Ionizing radiation
