Based on the wording in the newest RRG, you may select 1 or 2 non-leader or non-operative trooper units to set aside until their token is pulled.
With that, can you use emplacement troopers, E-WEB/FD Turret, (supports) to be set aside?
If you can, why aren't more Rebel players trying to bid for the ability to place a turret on the field further than the normal deployment zone? Or likewise, Empire with the E-WEB?
