You late bro. Nobana already posted this stuff. Well what i have experienced myself, is that with rocket pods i don't even disable vehicle, nor kill people with it. With guided missile (and beam tracking) i first fire the missile, then fire as long as i can with my gatling gun, and i usualy get "vehicle disabled" and sometimes even destroy. In Rush guided missile also speeds up killing tanks, and is much better choice in my opinion because you can fire that missile, and shot with your gatling gun at same time.
