This CNNMoney.com article
has an interesting review of USAA Bank's history:
From its 1922 start insuring officers, USAA has expanded into many other areas, including adding a banking unit, USAA Federal Savings Bank, that has grown to $43.6 billion in assets and is now the country's 31st-largest bank in terms of deposits.
Most of the article is on USAA's focus on the military market, and how other banks like Chase and Wells Fargo are also targeting this market. It failed to mention that USAA offers most deposit products to everyone. However, this hasn't always been the case, and based on some quotes in the article, I wonder if USAA may decide to limit banking once again. The article ended with this quote from USAA Bank's president, David Bohne:
"The only sandbox we want to be in," Bohne claims, "is with our military men and women."
