Anti-Tank Magnetic Mine (C13.7)
A hand-placed magnetic charge that never gets a counter of its own. Any German Infantry unit from 1944 on is treated as possibly carrying one. An unbroken, unpinned German unit attacking a vehicle in Close Combat can declare an ATMM attack before resolving it: on a Check dr of 1-3 a man gets it placed, which adds a -3 DRM to that attack.
