I'm trying to play through SA vanilla without the editor or cheat mode, so it took me a while to figure this out in-game. Then I finally broke down and opened up the editor and spawned a stomper to test explicitly.
It seems like land mines do *zero* damage to stompers. They just get destroyed by the legs. This seems very counterintuitive to me, but I guess stomper legs are invulnerable similar to demolisher segments?

I swear I searched for "land mine" and "landmine" before posting this :/
