This bill aims to provide critical support for veterans who served at Karshi Khanabad Air Base (K2) in Uzbekistan by establishing a presumption of service connection for a comprehensive list of diseases. This means these conditions will be automatically considered service-related for eligible veterans, simplifying their access to benefits. The legislation amends title 38, United States Code, to include a new paragraph specifically for veterans who served at K2. The presumptive conditions cover a broad spectrum of illnesses, including any cancer , any thyroid disease , any cardiovascular disease , any neurological disease , medically unexplained chronic multisymptom illness , and cataracts , among others. This measure is designed to ensure that veterans suffering from these conditions due to toxic exposure during their service receive the necessary support without undue burden.
