After getting the Ace intel it told me to go to the Major to get the other contracts, but all that came up was the Ace. It looks like they miswrote the script and your contact should not have pointed you to him. Instead, look on the map and go to the base that has the flag showing up on the map. AFAIK the Allied commander gives you the ace while the other factions give you the King/Queen/Jack.
If I remember my progression correctly, this was the way it happened for me. I found the King/Queen etc on intel I received after missions for the Chinese/South Koreans.
