I can't be sure, because of my young age and the long-deadness of relative, but paternal grandfather (WWII), I think had one of those and some other stuff. No idea -- it was just a kind of little wooden box with a bunch of war stuff in it (tiny, like 10cmx10cmx6cm, and, IIRC, a rosary. I think that was the first time my mother told me that some people believed in the crucifix Jesus above my bed and all that, and I literally could not countenance such an idea. I think I must have been four or so, because I know I said so. I was kind of a shitty little kid.
TNP is surprised by how many military veterans he or she has actually become friendly/acquaintancely/co-workerly with over the years.
no, I wasn't talking about combat stories, just tales of people who just enlisted, or were commissioned, and have tall tales to tell about "this time in training" and other funny anecdotes. I've never heard anybody talk about combat IRL.
