Can You Identify These Pictures at the Fort Custer Library?

Some of my readers know that I volunteer at the Fort Custer Historical Society library. It isn't open to the public because my helper, Jan, and I are still in the process of inventorying things. 

Our latest project is working on the thousands of photographs in the library. We grouped them by war or subject. If a photo didn't have any identifying information, we scanned it using Google Lens. The photographs below are the ones needing identification. 

This is where I need your help. If you can identify anyone, anyplace, or anything about the photograph, please leave a comment below or email me at brae957@gmail.com.  If you know which war it was, which arm of service it was, or even the smallest hint, I would be grateful. Thanks for your help. I will update the photographs as I get more information.

The numbers are under the pictures.
