I also don't see how this helps REX, as it virtually guarentees their people will be leaving after five years. I take it (or at least I hope!!) that a raw Cadet would need at least three years on the line before getting a command,so, with time for training, they would be in the situation of upgrading a guy for a on year return before he went off to the land of the Orange star- and let's not start on where they're going to get training staff!!
