I know for KSU in general we are required to Read "The Namesake", and for ROTC we are required to choose a book by a Former Officer and write a detailed report of it.
Although this is not manditory at the Academy, this is a fairly new program intended to improve leardership characteristics within the fleet. It's a great source for reading lists for civilians also. The collections are broken down into five catagories:
Junior Enlisted Collection
Leading Petty Officer Collection
Division Leader Collection
Department/Command Leader Collection, and
Senior Leader's Collection
Within each collection, it's broken down into the following categories containing two books each:
Critical Thinking
Joint & Combined Warfare
Leadership
Management and Strategic Planning
Naval and Military Heritage
Regional and Cultural Awareness
