Sure.
Place a mine of your choice anywhere on the map, (I've had problems with all mines except for the "Mines" and the "Small Floating Water Mines", they slide down the landscape, very anoying. If you know how to solve the problem then please let me know.
) Give the mine you've placed on the map a name, (like "mine01") then place a trigger looking like this:
axis a, axis b: any size you wish
activation: here you can put either west, east, resistance, gamelogic, anybody, etc... but if you choose anybody, then make sure the mine isn't in the trigger's range, otherwise it will explode at the start of the mission. And ofcourse choose "present". Example: Activation: Anybody present.
On Activation: mine01 SetDammage 1
Thats it.
