Okay, so the Armor didn't stop all of the damage, and your Body Type Modifier wasn't enough to shrug off the rest it's time to take a Wound.
The Wound section of the Hardcopy Form is used to record damage. For each point of damage taken, check off one box, moving from left to right, top to bottom. The top line of this section (marked LIGHT, SERIOUS, CRITICAL, MORTAL, etc.) tells the overall state of the character's health.
Special Wound Cases
Limb Loss: If a character takes more than eight points of damage to a limb area in any one attack, the area is severed or crushed beyond recognition. The character must make an immediate Death Save at Mortal 0. A head wound of this type will kill automatically.
Head Hits: A head hit always doubles damage.
