Armor Values
Each battlemech has an Initial Penetration Value (IPV) and a Structural Point value (Str. Pts.) The IPV is the numerical value of the amount of damage a single shot must cause to penetrate the armor and cause damage internally. The Structural Points are the total amount of damage the armor can take before it is rendered useless.
Penetration and Remaining Damage Energy
When a shot has enough power to penetrate the armor, the IPV is subtracted from the total damage amount and the difference is Remaining Damage Energy (RDE). RDE is applied to internal damage. (see damage tables)
Weapon Armor Values
Each weapon has an Armor Value. If a Location which holds a weapon is hit, there is a chance the weapon is hit. This percentage also applied to Jump Jets and other equipment.
Weapon Hit Percentage Table
| Head | 20% |
| Left/Right Torso | 35% |
| Center Torso | 25% |
| Left/Right Arm | 55% |
| Left/Right Leg | 50% |
If a Weapon is damage beyond its armor value, the weapon is destroyed. When a missile rack is hit, the missiles loaded (if any) explode. Treat as a critical hit.
Ammo Hits
Ammo hits are determined differently. Because the ammo is usually place behind the IPV value of the armor, the ammo hit is determined after the IPV value is applied. There is a 20% chance that an ammo area in that location is hit. Treat the RDE hit as a Critical hit.
Battlemechs and Screens
All mechs can have mech versions of personal screens and have an limited supply of energy, based on the mech type.
| Light Mech | 10 hits |
| Medium Mech | 20 hits |
| Heavy Mech | 25 hits |
Internal Damage and Critical Hits
Internal Damage is determined by adding the RDE/10 to a 2d10 roll and consulting the location internal damage table. Each location has a table.
