Getting the AKS-74u Suppressor
Right after you fight the Harrier Jet, drop down from the ledge to the pipe. From the pipe, do a roll, (flip if you're Raiden) across the pipe to the PSG1 ammunition. Head up the stairs and get the other ammunition. Use the coolant to spray out the fire on the left and congratulations, you just got the AKS-74u Suppressor.
