We have created a Sgt Major position in our association and want to do it right. So far we have done a fair amount of research on both early and late war. We know what they're supposed to do, where they're supposed to be in formations etc., and what the dress uniform is for the Sgt Maj. What we want to be sure of is exactly what the "duty or field" uniform is.
We have so far only been able to find one picture or painting indicating what is believed to be the uniform. That painting is of the Sgt Maj of the 54th Mass., which shows him in the same field uniform as the other NCOs. Would appreciate any information or direction to sources that would help in doing a bit more research on the subject.
