Two confederate soldiers surrounded by blue aura.

A blue aura is a game mechanic used to distinguish soldiers who are supposed to survive the war from those who the player is free to kill. If the player decides to kill two such people anyway, Opposition Soldiers are dispatched to kill him. Players may opt to deliberately kill blue-aura soldiers to call in the Opposition and steal their more futuristic weapons.

Otherwise, Blue Aura characters can be taken down nonlethally by being shot in the limbs, or with chasers.
