The purpose of this legislation, known as the "Valor Has No Expiration Act," is to ensure that members of the armed forces who may have been overlooked for military decorations due to classified records can still receive recognition for their service. The law aims to address situations where awards were not granted in a timely manner because the necessary documentation was not available to the public due to national security concerns. Key provisions of the law include the ability for military departments to waive time limitations on awarding decorations.
