- Reaction to tactical change

- 0: Move when ready (default AI) - Act as normal.
- 1: Move when seek cover - Move when cover is needed.
- 2: Move immediately - Move to a different position (if we want to) as soon as the change occurs.
- Player battleline
(PlayerBattleline)<boolean> - Should friendly NPCs use the player as a battle line?
- Stay at cover location
(StayAtCover)<boolean> - If current cover is suitable, should NPCs stay there and not advance?
- Abandon if enemies hide
(AbandonIfEnemyHides)<boolean> - If NPCs haven't seen enemies for a set amount of time (Enemy hides abandon time), consider the standoff to be over?
