Vehicle Armor Hardened?, How does vehicle armor work? Options

[fulcra]

Vehicles do not need to resists damage unless the modified DV of the attack exceeds their armor rating. Couple of questions about this.

1. Is there any difference between hardened armor and vehicle armor? In previous editions it was specifically stated that vehicle armor was hardened, but that was avoided in 4ed for some reason.

2. It appears that short bursts are the only attacks that don't count towards the modified DV for comparing against armor. Is that correct? Do long and full bursts add to the DV for comparing if the vehicle should have to resist? Does firing a long burst or fully-auto at a vehicle help get through it's armor?

3. Does this mean that a vehicle with say 10 armor, and say 20 body, never has to resist damage if it rams something at the lowest speed category. (since the damage to the ramming vehicle will always be half it's body, in this example, 10.) If that's the case, do the passengers need to resist the damage still, or not?

Thanks!
