===More Than a Nice Paint Job: Armor Values===
All vehicles have an armor profile, split into three numbers: Front, Side, and Rear. These ''Armor Values'' mostly range from 10 to 14.  AV values are roughly equivalent to Toughness values 4 below them, so ''AV10'' is roughly equivalent to ''T6'', while ''AV14'' is roughly equivalent to ''T10''.  However, ''AV'' is stronger against weak weapons than ''T'' for the same equivalent value, as ''AV'' becomes immune to attacks one S point faster (with AV10 being immune to S3 weapons or weaker, while T6 is immune to S2 weapons or weaker), and weaker against strong weapons (AV10 will be wounded on a 1+ by an S9 weapon, whereas no weapon of any strength can automatically wound T6).  Also, it is typically much more difficult to get saves onto your Vehicles (and downright impossible to get armour saves onto them) than it is onto Infantry, so in practice, AV is deceptively fragile and Vehicles will die faster than a Monstrous Creature of similar Toughness.

!10
|Super-Light armor. Not even armor, really, just a plate covering the structure of the vehicle. Usually found on small, fast craft and the rear of heavier vehicles. A Space Marine can ''punch'' through this.

!11
|Light armor, or some actual armor plating. Scout vehicles usually get something like this. A Space Marine can't punch through this, but a Heavy Bolter can. It'll stop most infantry weapons but crumple before real firepower.

!12
|Medium armor. Now we're talking! This is the first armor value that takes dedicated anti-tank weaponry to fight, and even a Krak Missile only stands a 50% chance of doing anything. The Chimera enjoys a front plate with this.

!13
|Heavy armor. Autocannons will barely scratch this, and Krak grenades will just leave an ugly scuff on the paint. The Predator has this, as does Necron Quantum Shielding.
| 9 || 6 || -
|- align="center"
!14
|Super-Heavy armor. The purview of walking, rolling and floating fortresses with a reputation for being stupidly hard to kill. The Land Raider and Leman Russ get this, as do most Lord of War slot vehicles. Either find a way around this, use melta weapons, or the strongest ordnance you have, because nothing else will work.

!15
|Titan armor. Mostly the realm of Fortifications, but some high-end Super-Heavies get it too. If you run into this...just give up.
