an explosive device that is buried in the ground
a weapon, an explosive or other substance (normally encased) used to kill, wound or somehow harm personnel, or to damage or destroy vehicles, boats, or aircraft
A land mine is a type of self-contained explosive device which is placed onto or into the ground, exploding when triggered by a vehicle, a person, or an animal. The name originates from the practice of sapping, where tunnels similar to a mine to extract minerals were dug under enemy fortifications or forces. These early mines were first collapsed to destroy fortifications above, and later filled with explosives and detonated.
Land Mine is a drinking game which involves players spinning a quarter and simultaneously drinking a beer. The game is popular on college and university campuses around the United States.
