Army camps in CA pre-WW2

[Vincennes]

I picked up these 4 real photo postcards recently. None are mailed or have any message on the reverse. They all have the AZO stamp box with 4 triangles pointing up, so they date to 1904-1918. Obviousely they were part of a larger set since I have #9, 10, 17,and 19. The first two mention Coyote, CA. That is a small village east of San Jose.

 

Here are the first two.

Here are the next two. I cannot find any of these Camp names (Blue, Sherwood, or Sargeant) on Google, so they were probably all temporary camps. Notice the use of horses in the photos.
