You can do this in any tank and in any game.
When a enemy shoots of your tracks or knocks out your engine you won't be able to move.
you can see if and what is knocked out on the bottom left of the HUD, there you have all the modules around the picture of the tank, if a module broken it will be colored in red and it will take some time to repair it, the engine or tracks have to be red in order to get the achievement, if it is yellow it is just damaged and you will still be able to move.
so you simply need to kill an enemy while not being able to move due to part of your tank is damage.
It will be easier to get it with an heavily armored tank because you will survive longer. but it is very situational.
Keep in mind! if you have a tank that has a repair box, or a crew that has the repair skill will make it harder to get it since you will get the module repaired fast.
