Michael Lecik Military Firefighters Protection Act This bill establishes a presumption of service-connection for specified diseases becoming manifest in certain veterans to a degree of disability of 10% or more within 15 years of the veteran's separation from active military, naval, or air service. Under a presumption of service-connection, specific diseases or disabilities diagnosed in certain veterans are presumed to have been caused by the circumstances of their military service. Health care benefits and disability compensation may then be awarded. Veterans addressed by this bill are those who (1) are trained in fire suppression, and (2) served on active duty in a military occupational specialty or career field with a primary responsibility of firefighting or damage control for at least five years in the aggregate.
