Vintage US Military sepia toned photographs set of 4 tank popular and planes

Art size (all): 9 1/2" x 7 1/2
Paper size (all): 8" x 10"

NOTE: Some of the photos are horizontal, some are vertical.

All photos show signs of age including fading and color changes, finger prints, some minor creases, and other minor marks. They're otherwise popular in good shape! They're printed on Kpdak photo paper. I am not a military buff so I don't know anything about the equipment in the photos. I just came across them in my journey and they looked cool.
