I had a fairly gruesome memory last night, I’m posting now as this is the first chance I’ve had, and I’ll be researching it ASAP. I really hope this one isn’t real.
The memory was that bear traps were used as improvised anti-personnel measures in No Man’s Land. Seems like they were mixed in with the barbed wire. I don’t recall reading that anywhere (although I know that after a certain point anti-personnel measures became sadistically creative).
Going to look that up in just a sec, will follow up.
