Infiltration havoc wreakers.

The mine-laying scenario described isn't that unbelievable to me. I see tanks in BF1942 that get mines laid around them all the time, by non-stealth, perfectly visible engineers.

Sometimes the tanker just sees an infantry run by close to his front, and doesn't realize it's a mine laying engineer. Sometimes they just hope they can miss the mines (or go slow enough to not set them off).

Mines are most likely intelligent, as the stealther ran away without setting them off.
