I mean how could you not want these in AnA supporting your landing forces?
Land Mines are a Single defense unit.
Cost: 2
Defense: 4 (d20 system)
Land mines can move (1). Must be activated to defend (country must state that mine is activated once placed or moved to desired territory). If an activated mine is attacked, a defensive roll is placed. Once rolled, activated mine is removed. Attacing units that are hit are removed as well. If mine is not activated and territory is taken, then its removed from play.
