Remote detonator

Don’t select a valid target. Instead, shoot against each operative within 2" of your Explosives marker, unless Heavy terrain is wholly intervening between that operative and that marker. Each of those operatives cannot be in cover or obscured. Roll each sequence separately in an order of your choice. This weapon cannot be selected if your Explosives marker isn’t in the killzone. At the end of the action, remove your Explosives marker from the killzone.
