Armor
You can use armor to protect your vehicle from munitions.
Thickness
Higher penetration threats require thicker effective armor to defeat.
In the clip above, 100mm is more than thick enough to stop a machine gun, but it is not enough for the high penetration rounds from a cannon.
Effective armor is the “line of sight” thickness that the bullet must pass through.
A thinner angled plate can have the same effective thickness as a thicker flat plate.
If you are interested, you can calculate effective armor with this formula:
\[\text{Effective Armor} = \frac{\text{Nominal Thickness}}{\sin(\theta)}\]
Tanks generally concentrate most of their armor at the front, then the sides, then the rear/roof/floor.
Health (Ductility)
With the same thickness, a healthier prop will last longer under attack.
Setting the ductility of a prop can change its health at the cost of weight, or vice versa.

Using the ACF armor tool, you can set the thickness and ductility of a prop:
