* During an Activation, explosions trigger after the PDS Fire step. 
* Mines can only be rolled once per activation, even if there are multiple mines present.

Space Mines are technically not considered units. 
== FAQ ==
Q: Are space mines considered units (for example, for purposes of the Diplomacy II Strategy or for Tactical Retreats)?
A: No. Space mines are not considered units.
Q: During the Production step, can you build a Cruiser and then immediately use that Cruiser to deploy a space mine in that system?
A: No. When producing units and mines during the Production step, all of a player’s units and mines are produced simultaneously. You determine what you wish to produce, pay the resources, and build them all at once. You therefore cannot build a Cruiser and then deploy a space mine with that Cruiser during the same Production step.
Q: Can Space Mines be scuttled?
A: No. Space mines are not units, and cannot be scuttled.
