I'm pretty sure that this has been answered before but repeated searches were fruitless.

In the scenarios from the GR-75 where the Imperials control six mines, when do they detonate? At the end of activation or during the end phase?

I've read through the booklet twice but I'm not finding it.

Any help would be greatly appreciated.

Never mind. Found it on the third read through.

Late hours and cold medication is not good for reading rules.
