"Watch out your RWR, because I'm comming."
First pick up the tippytoy and spawn the launcher vehicle
along the vehicle there's a big controller that looks like a military telephone
spawn a stinger battery and insert it into the right whole of the controller
then press the right joystick and use your head direction to lock on enemy
once the sound change from "beep,beep" to "beeeeeeeeeep"
push the left joystick and pull the trigger and missile should be on its way.
(man I just repeated how to use stinger I guess)
Can't make the custom battery working so you need to spawn vanilla stinger battery
and basically this whole thing is just a stinger, so you only got one missile per vehicle...
