I have a question, and I apologize if this has already been covered elsewhere. But what skill would be used for planting demolition charges, like if the mission or task was to blow up a structure or disable a ship or vehicle? I was thinking Mechanics, but Ranged (light) is used for planting mines IEDs so I figured that might be used instead. But After trying to find something in the RAW, I am confused. Any help would be appreciated.

_{Mechanics for actually destroying a structure with a place charge. Skulduggery for hiding the device/getting it to the target unnoticed (or Stealth if you're truly hiding).}

or Athletics if they set the timer wrong!

I'd ask for a dice pool of Cool/Coordination + Mechanics/Computers to set a demolition charge depending on how it is constructed.
