The term "pocket litter" it a technical term in military intelligence; it is quite literary the stuff you find in captured soldiers pockets. And one of the things you can find is shave gear...
I was reading a very interesting article on German WW2 pocket litter, and realized a couple of thing when I saw this photo:
In the bottom row there is a pack of razor blades, a razor and a loose razor blade. There is a possible shaving brush in the top row, and a mirror more or less in the middle of the table. Even soldiers in the field wants a shave I guess.
