Armor usually refers to body armor worn by humanoids, though there are other situations where someone in body armor wears power armor.
There is also cyborg armor and even robot armor.
Body armor for robots[]
Page 152 of the original Vampire Kingdoms had a note under the Dragon Skin Armor worn by the Pogtal Dragon Slayer.
- The armor is not really suitable as additional protection for robots.
- Draping a giant bot in the armor requires special modifications/alterations of the armor's design and may still block and prevent use of robot weapons, jets, and sensors.
- Covering cooling vents, exhausts, or jets may cause overheating, too.
- Also adds to clumsy and awkwardness factor: usual penalties apply, plus -1 to parry/dodge.
- The cost is also prohibitive; it's cheaper and more efficient to get conventional armor.
This implies there is "conventional armor" available for a "giant bot" supplemental to their basic MDC. Though it's unclear what this would be.
