If you had to pick a special duty, which one would it be? I am going to work to get in shape for the JCU special duty, but if they wont take me I might have to look at a more conventional special duty. See my career is constrained right now, and I may not get a CJR to re-enlist. I want to stay in, but I don't want to cross-train. A SD is one way around this problem. The only one I don't qualify for is PME instructor (must be E6 I think).
