- Improved Operation: At rank 4, 8 and 12, a character with the combat armor or powered armor skill can reduce the action check and Dexterity resistance modifier penalty of the appropriate type of armor by one additional step.
- Shaking Off Stuns: A character with the combat armor skill at rank 5 or higher can attempt to “shake off” some of the stun damage he suffers in combat. Once per round, the character can make a skill check; an Ordinary result allows him to ignore 1 point of stun damage inflicted in that round, a Good result allows him to ignore up to 2 points, and an Amazing result allows him to ignore up to 4 points.
