In order to get the special weapons to unlock you need two very important things. First you need to have the updated version 1.12 and second you need to unlock the first unlock to get the second. Simply just log into special forces from the manage account screen (If you don't have BF2:SF just find a friend who does). Play one round of any map. After a side wins and it starts to load the second map, push esc and log out. You have to wait about 12 hours until the game updates your scores. After 12 hours log back in to BF2 (not Special Forces) and it should prompt you that you have an unlock. If it doesn't work then you do one of two things.
1. Wait a while longer for it to update adn check your stats to see if it did.
or
2. Log back into Special Forces and check to see if it would let you unlock there.
