I have a friend who knows a recent Naval Academy grad that once his four years at the Academy were done, he received a letter thanking him and letting him know that his services were no longer required. No mental or physical problems. How rare is this? Is it just a handful or is it 10% of every class. My friend said this guy said its 10% but that is hard for me to believe. Can anybody shed some light on this? (he graduated roughly five years ago....) Thanks!!
