Remember you can travel from a map to another if you uninstall a linked teleport catcher and bring it to your destination.
Neat feature, so you just need to send out 1 pawn attack caravans, place the catcher and call reinforcement. I hope they can teleport back too :-)
Another idea would be that the catcher could be mobile on a caravan, so you would have remove access to your homebase.
Or you could modify a transport pod with integrated catcher. You could direct use after the pod "land" at the destination map (encounter only).
And a last idea for the TP bench, they normaly need to be operate with a pawn, a further research to use a AI core so it auto. operate, maybe at a lower efficience then when a pawn would do it.
