Border HQ have acquired 4 new triggers from the recent expedition, and they could, very well, get other triggers from previous expeditions which they did not incorporate/assimilate to the current trigger set. We have seen from the recent invasion, Galapoula invasion of Border HQ, that Yomi discovered the vulnerability of Idaten of Futaba and Kinuta felt concerned over it. We also saw that the Galapoula has integrated Bail Out in their trigger set. So it's quite normal that the invading forces are using new trigger set in the invasion to elude the possible retaliation from the invaded country's preparation.
We know that the Aftokrator has a fair knowledge about Miden/Border's triggers and their ability. So invading Aftokrator with the same trigger set would be strategical mistake and folly. Therefore, we may end up seeing the expedition army to Aftokrator will use new trigger/s in their trigger slot.
