Armor System
The armor system of Natural Selection is fairly complicated.  However, for the basic purpose of determining the strength of a class, it can be summed up as the following:

One armor point is worth...
 for marines: 2 health points
 for aliens...
   at 0 hives: 2 health points
   at 1 hive: 2 health points
   at 2 hives: 2.5 health points
   at 3 hives: 3 health points

Again, though, it is actually a bit more complicated.  There are two main components to the armor system: damage absorption, and damage negation.

When damage is taken from an attack, one portion of it is directed to armor, while the other portion is subtracted from the numeric health amount.  Damage absorption refers to the portion of damage that is directed to armor.

The damage absorption percentage is...
 for marines...
   with light armor: 70%
   with a jetpack: 70%
   with heavy armor: 95%
 for aliens...
   with 0 hives: 70%
   with 1 hive: 70%
   with 2 hives: 80%
   with 3 hives: 90%

Of the damage that is directed to armor, a portion of it is nullified.  The remaining damage is then subracted from the numeric armor amount.  Damage negation refers to the portion of the damage that is nullified.

The damage negation percentage is...
 for marines: 50%
 for aliens...
   with 0 hives: 50%
   with 1 hive: 50%
   with 2 hives: 60%
   with 3 hives: 66.6% repeating

For every class, the damage absorption is sufficiently high and negation sufficiently low that, under normal circumstances, all armor is depleted long before the health is.  This is why for most purposes, the basic summary, given at the top, is sufficient.
