what was the date when enlisted personnel are first authorized acceptance into usaa?

USAA (United Services Automobile Association) is a financial services company that provides insurance, banking, and investment services to members of the military and their families. While USAA membership was originally limited to commissioned officers, it has since expanded to include enlisted personnel and their families. According to USAA's website, the eligibility requirements for membership have evolved over time. In 1996, USAA opened its membership to all enlisted personnel who had served at least 20 years in the military, as well as their spouses and children. In 2009, USAA expanded its membership eligibility again to include all enlisted personnel, regardless of length of service, as well as officers and their families. Therefore, it is not accurate to specify a single date when enlisted personnel were first authorized acceptance into USAA, as the eligibility criteria have changed over time. However, it can be said that as of 2009, all enlisted personnel were eligible for USAA membership, and the company continues to provide a range of financial services to military personnel and their families.
