Sir, you missed a few of the guys who claimed to be 18D's when they weren't even in the Army (the most notorious was the SARC who claimed 18D and SEAL and Marine Recon), and the guys who were in the Army but weren't SF and had never even attempted an 18 series MOS... who were 18D's because they went to SOCM. And then would argue with 18D's that they had done "the training"...
Hence the chapped ass about this subject.
As an aside, I know a guy who was a SSgt with 1st Force (MFF JM, S/S, DV) who transfered to the Army, went to the long course, became an 18D, left the Army a year ago because they said they were over on 18Ds and wanted him to retrain as an 18B so he lat moved to the Navy to be a SARC. He is thinking about going to BUD/s or possibly the PJ route. He is also a school house Ranger.
I know what you are talking about but you get wannabes in every community. I am a big proponent of being proud of who you are and be the best at your job. Even if it isn't a "cool" job. One of the SNCOs I respect the most is a shit hot admin chief. By the way we used to send guys to the Q course in the nineties. I know two guys who did it (but I am not sure if they did robin sage). Did any of you guys have any Marines in your Q courses?
