Not Americans I know, but Britshers cooking in their Helmet in WWI, officers of the Grenadier Guard, Miraumont-le-Grand_ in France year not mentioned. So we figure if they did we must of did too with the Brodies, will keep the lookout for Doughboys cooking in their helmet

The cord uniform was used by all five branches of US service, two green and three blue, the same fabric color was used for each group although the pattern and cut were specific to each.  Worn by both Officers and Enlisted of any specialty or job, it was not exclusively for medical staff like the hospital whites.  The insignia was US standard for the time, ENLISTED; collar brass, rank on sleeves, ribbons, name plate,  OFFICERS; rank and branch on collar, ribbons and name plate.  That said in country various unit patches were worn similar to pocket patches and in many positions, see photos.  Cheers Armygas PS: the buttons on the Army version were "bronze color" initially and common brass after about 1962, both were same size at 30 ligne.

When did they start with the Black Twill Cloth, up till now I was only familiar with the OD ones, like in example when I was in Alaska 81-82, one of the Squad Leaders a E-6 wore one for previous duty as a recruiter, in Boston Mass he was, his, it was of course in OD cloth.

Thanks for posting that one. I know it's in the reference books but I've never seen an actual one "in the flesh" so to speak.

Hello Thanks for sharing. It's curiosus, I just acquired some of his belongings. It's a shame, who knows how many more of his things are scattered out there among other collectors...

You are talking about the Official Squadron Insignia-----It was members of the RAF who gave me the information about the Unofficial " Nellie" Mascot insignia as well as the Home Front Forum.   They have a new one now which shows an aggressive elephant

Of course that’s the entire package that weighs 1 kg.

Does this help?

Not much is all I can say shibalegend.
