Sorry to intrude on the seniors forum, I am only an instructor in the ACF but I have questions regarding uniform that I think would be best answered here. 1. Where should the badge of rank for sergeant major (SMI) be worn on no2 dress ie how far between elbow and cuff 2. Do sergeants major wear different shirt and ties in no2 dress to SNCO's. I use the term sergeant major as there are no Warrant Officers in the ACF. Thankyou in advance for any help/advice.
