Question: can scv repair inside bunker?
Answer: SCVs set to auto-repair (Alt + R) that are placed in a Medivac/Bunker will automatically repair any other mechanical units inside of the Medivac/Bunker. However, SCVs inside a Medivac/Bunker cannot repair the Medivac/Bunker itself while they are cargo. They must leave the Medivac/Bunker in order to repair it.
