AMMO

JHP - Jacketed Hollow Point AP - Armor Piercing FMJ - Full Metal Jacket 12S - 12 Gauge Shell MFC - Micro Fusion Cell SEC - Small Energy Cell

The type of ammunition used will change the amount of damage dealt to the target. JHP is always the superior choice, followed by FMJ. Forget AP ammo. AP is, in the first place, more expensive, and although it does penetrate a bit more than JHP ammo, it deals very little damage. It's useless against anything - JHP is always superior. Shotgun Shells deal good damage regardless of the target used, and FMJ is like a 'neutral' ammo - it works okay on both armored and non-armored targets. It doesn't suffer nearly the damage penalty of AP ammo, but it penetrates far better than JHP.

As for energy weapons, their real effectiveness depends on the type of weapon used. For instance, laser weapons aren't as effective as plasma weapons on armored targets. Plasma is good against anything except for Tesla armor. The Alien Blaster uses a different technology (and from the death animations seen from Fallout and Fallout 2, I think pulse) which is goes through any type of armor. The cells themselves don't serve as damage modifiers, but are merely power units.

ARMOR

Consider combat armor, which has a damage threshold of 8 hit points and a damage resistance of 60% against laser attacks. (8 hp/60%)

The way armor works is like this: if you are wearing combat armor and somebody hits you with a laser rifle, you will receive x amount less. Say that if you're wearing the Vault 13 jumper, which has no protection whatsoever, and the enemy uses the laser rifle and hits you for 42 hit points of damage.

Take the same situation with combat armor on. The armor will naturally deflect 8 hit points of damage because of the damage threshold. Now only 34 hit points remain. The armor can resist 60% of that damage. Multiplying 34 by 60% will give you 20.4, and rounding that down will give you 20. You'll only take 20 hit points of damage with the armor instead of 42.
