1) One hunter with machinegun; was destroyed at second or third turn. If I understand correctly, it became a real "scout" now since it can be detroyed even with plasma pistols
2) All six soldiers were in jackal armor
3) Second time one soldier got laser shotgun, and even killed one "disc" with it.
4) Never heard about wolf armor
The squad was 3 riflemen, 2 snipers, one machinegun and one hunter with machinegun. No special formation was used, just tried to keep soldiers together and place them behind some objects wherever possible. Also both times the battle happened during night time; spent a lot of action points throwing flares in all directions.
First battle happened about 5 october game time. Then I've loaded some older savefile and second time the terror event happened about 17 october. I had 10 scientists and they were working at one project at time; there were almost no breaks. By that moment I've learned "alien biology", "foxtrot", "jackal armor" and started lasers (second time they finished lasers too).
Maybe I could try to kill sebilian, take his rifle and try to use it against dark beasts, but I'm not sure.
