YearBooks / Army Photo's?
I've noticed on some divisional sites out on the web they have 'Yearbooks' basically made up of photo's of each units personnel.
I was wondering, at one time or another, did all units take these photo's, and is there an archive of them anywhere.
I would be interested to know if there is a photo of my grandfather from his army days since we dont have any photo's of him at all.
I appreciate your help,
