As I've come to understand it Gravano was a Soldier on 12/16/1985. What then made him so important that he was approached by Ruggierio (spelling) to get him to support the move on Castellano?
It's true he was only a soldier at the time. I think he was approached because he was still quite close to castellano which may have worked to gotti's advantage. also he was a good earner and was a good hitman so he could help set up the hit
