Thanks guys, and yes, I meant to type Past Life Enemies, I don't know why I had Hunt Them Down in my head.
I am well aware that having C-3PO focus them will certainly be beneficial, my question was more about whether C-3PO was required in any way for the Rebels, and it seems he is not. I thought this was kinda strange, since the mission details reference him quite a bit. ricope, thanks for the bit about Doors are destroyed (removed from map) when it has suffered damage equal to its health , as that's really the key here. I thought that was probably the case, but I couldn't remember the RRG specifically mention that, but it certainly does under "Attacking Objects".
