Supporting Disabled National Guardsmen Act

This bill expands benefits for National Guard members injured during state duty. It allows members to qualify for military retirement pay based on disabilities incurred while performing "State active duty" (e.g., responding to natural disasters under state governor authority), not just federal deployments. It also creates a new VA health care program covering treatment for disabilities from state duty, with limits: VA care is only provided after exhausting other insurance claims and subject to annual funding. These changes directly affect National Guard members injured during state missions, ensuring they can access retirement pay and VA medical care without duplicating existing federal or state disability benefits.
