"collatereal" objective hexes

[Mad_Dog]

I don't understand totally myself, but when you cause a casualty in them, that is a point against you. You can take them by assaulting them however. Here is what the manual says:

Collateral - The point value of these objectives increases when enemy fire affects the hex they are in. Collateral Objectives can be assaulted however without causing the point value to change. Collateral Objectives do not change side. If a Collateral Objective has a positive value, then that value is awarded to the owning side (regardless of who occupies it). If a Collateral Objective has a negative value and is occupied by the opposing side, then that value is a penalty
