All forms for Navy Federal will be in the permit to report package. You can change to other banks however, Navy Fed has branch on yard and is very convenient. Other option after he is at USNA as will need to have his alpha number is USAA. USAA is also good for Renters insurance. They have an office outside Gate 1 so you might want to check them out.
As much as you may think that your Mid does not need renters insurance I would advice getting it. Although it should be a "safe" place - don't count on it, things do go missing. Especially if they have sporting equipment - bike golf clubs, laptop computer, Iphone, and of course by second year class ring.
