That was what I was thinking but base armor ratings are calculated at 16/ton (standard armor) with modifiers based on types... Inner Sphere Ferro-Fiberous is x1.12 and Clan is x1.2 etc...

Barrier armor rating.
All common BT vehicular weapons and most forms of armor in Battletech have a BAR of 10.
This "B.A.R." is what determines the protectiveness, penetrativeness, etc. of the armor. How much it protects against penetration and other factors.
"Basically any unit that is not built on an Armored Chassis hit by a weapon that inflicts more damage than its BAR will need to check for a critical hit, even if the weapon did not damage internal structure.[1] So a Silverfin coastal cutter (BAR 7) hit by a PPC blast will have to check to see if it sustains a critical hit as the artificial lightning leaks through a small gap in the armor plating."
"Heavy Industrial armor is functionally the same as BattleMech armor, with a stated BAR of 10.
Industrial armor also has a BAR of 10, but only offers 67% points per ton that Heavy Industrial armor does. Industrial armor is very similar to Primitive Armor used by the first BattleMechs.
Commercial armor offers 50% more protection per ton of weight, but only has a BAR of 5."
This unfortunately has a very limited coverage, and doesn't list weapons.
For example I read some time ago that 10 damage on a battlecruiser in space is either 100 or 1,000 damage against a battlemech whose BAR is far inferior, as well as the massive critical rolls necessary.
So I was wondering about a list if at all possible.
The basic concept sounds like if I have a BAR of 5, then taking 5 damage or more from a single weapon's attack would require me to check for a through-armor critical. So that might summarize weapons. But then I have about 16 types of armor and a number of chassis types just for mechs alone. Do I assume all except those that specifically say otherwise have a BAR of 10?
Then there's a number of different BARs for vehicles, some I seen with 12, some with 6, the Silverfish Cutter there says 7, and then there are some vehicles with a BAR of 1 (I'd hate to be in that).
