"Round, metallic looking piece, halfway stuck in the ground, placed in west Germany. Was afraid to get closer. Explosive? I called the police. They cleared the area and send me away."
"Possible anti-armor/tank mine. It looks in good condition and does not have a fuze or place for a fuse. The lack of rust indicates it is either concrete or some non-ferrous metal. It is very similar to a USA produced training mine except it isn’t painted/marked as inert."
