First Wave
The first wave of lion hunters engages with whatever threat comes to their town. They don't have a choice.
Based on how they fare against the threat, the rest of the town reacts. If the otherside is overwhelming, the second wave with a much larger force intervenes and the rest of the soldiers are to start making preparations.
Preparations are for two scenarios. One of them is to tackle the enemies that are coming at them and another one is to create a destruction plan and escape from that spot.
But if they are consciously following that plan, they should at least be preparing right now. They didn't show any emotions. They are just robotically doing the same monotonous activity they are doing until now.
Only the first wave of lion hunters arrived with some ferocity.
The two undead creatures that stayed back with Sam made a move on these soldiers.
