Yeah man first of all, DA Pam 623-3 says that rater specific bullet examples are mandatory to explain a NO in the height/weight box.
*edit, whoops pressed post now too fast.
Anyways, DA Pam 623-3 also specifically says that bullet comments are mandatory regardless of the rating given. It also says right on top of the NCOER form that bullets are MANDATORY and SUBSTANTIVE bullets are required for "EXCELLENCE" or "NEEDS IMPROVEMENT".
My question to you is, how did you possibly sign this and not talk it over with your rating chain first?
