What color PT belt is worn on your Post? and who wears what color?

Almost every Post has different regulations regarding what color reflective belts are worn for PT. Some had hoped the new 670-1 would establish an across-the-board policy for color of reflective belts worn with the APFU, but alas it makes no mention besides "Command discretion".<div><br></div><div>To start off, the last Army Post I was at (Ft.Bliss) wears:</div><div><br></div><div>Blue - Officers</div><div>Green - NCOs</div><div>Yellow - Junior Enlisted</div><div><br></div><div>Additionally how do you guys feel about your posts policies regarding reflective belts? Personally I'm in favor of Ft. Hood and similar posts, where everyone wears one color w/rank pins. We're all equal in PT, why the need for different color belts? In fact, why the need for rank pins either?</div>
