So I am new to a Cav Troop, and trying to figure something out so I dont look ate up. I have been told that everyone in the Troop is allowed to wear the Stetson in the Squadron areas on Fridays regardless of MOS. Since I think this is a cool tradition, I would like to get one to wear, but dont know what color cord I should put on it. I am not a 19D, so I dont know if I would be allowed to wear the yellow one. Im Chemical, and have seen the dark blue cord for it, but not sure if I should get that one. Everyone I have asked at my Troop doesnt know which one I should wear either...so Im a bit confused. It seems they havent had an NBC NCO for about 3 or 4 years, so no one has ever asked the question.
