The main purpose of the Veteran Suicide Prevention Act is to address the serious issue of veteran suicides by requiring a thorough review of the circumstances surrounding the deaths of certain veterans who died by suicide. The goal is to gather data and insights that can help improve the safety and well-being of veterans, ultimately aiming to reduce the number of suicides among this population. Key provisions of the Act include a mandate for the Secretary of Veterans Affairs to complete a comprehensive review within 18 months of the law's enactment.
