This photo looks to have some of the same people in it. Fort Mojave did use Mojave's as scouts.

I didn't know that about the hat disks, so its complete fantasy when coloectors claim its correct for ww1. But you are right so many collectors do that with campaign hats. Regarding the cord would this be correct for medical department? I don't think its engineer it doesn't appear to be the same color. Unless the red faded over time.

Living in Montgomery in enjoyed the post card.   Great research and thanks for posting the hat.

Greetings,   Avirex (1998 contract) and Cockpit (2007 contract) models had two interior pockets and a pen pocket.  Keep in mind when pen-pocket is mentioned, its in one of the two interior wallet pockets, not on the sleeve.  These models are also found with side entry pockets.  Weird side note:  The Avirex and Cockpit models are identical to a reproduction A-2 made by Banana Republic in the 80's   Best,   PEter

Sure they would. I don't think the design details changed until after the war. I also don't think early or late WW1 service hats were much different if at all. Plus, just because an item changed somehow doesn't generally mean the older stock would not be sold or issued until exhausted.

Yeah there's definitely evidence to support everything so far. That also explains the hat, he probably bought the hat in Montgomery when he was in Alabama for training. But then the question comes would early campaign hats still be available for purchase in 1917/1918? It looks like he enlisted in August 15 1917 if thats correct?

Could be both, I believe.

Are these 11th airborne division patches from WW2 period or after ? 

Running with the strong possibility the soldier W. A. Fisher was in the 145th Ambulance Company, this turns up in the Ohio WW1 Roster -- perhaps the original owner. Dennis

In 1929 War Department Circular No. 5 (26 Jan) gave all regular army personnel the option of wearing, off duty, the blue uniforms that had been authorized before WW1. At their own expense, of course. The specifications were to be the same as the last regulations before the uniforms were suspended, Special Regulations No. 42, Specifications for the Uniform of the United State Army, August 1917, with the exception that the dimensions of the cap would be the same as the current service cap. The picture shows the "dress" coat of a major general. Here is a 1908 illustration of the coat.   They did not. The uniform regulations of the time did give three- and four-star generals and the Army Chief of Staff the option of prescribing their own collar and cuff ornamentation on the full dress coat, special evening dress coat and blue mess jacket, though.
