As I understand it, this policy was implemented because guys who had involuntarily been changed from another MOS (typically B or C) to D were intentionally failing in order to go back to their original MOS. The problem is that I am not sure that the problem was as widespread as the command believed and in any case, just because a guy does not have the aptitude to be a D does not mean he would not be a good B or C. This is a problem is SWCS. I had a guy in my class, for instance, who was selected as a C, attended CLT and SUT as a C and then three days prior to the start of the D course was told that he would now be a C. He is still in the course but he is struggling. I think that he would be a good B or C but they needed bodies to fill D slots and he (and many others) got pulled at the last minute to fill those slots. That's not good business to begin with but to then tell these kids that if they don't have the aptitude to be a D then they can't be SF is just wrong.
In any case where was this involuntary 18D thing when I went through the course? Instead of being an 18C re-classing to 18D now I could already be an 18D, dangit.
