On Kamino, during the first level, you will notice spinning generators. They are glowing with red and make a specific sound on start up.
If you throw something into them, the object will bounce off like in pinball.
So the idea is simple - grab an enemy, there lots of basic troopers on this level who will make a great pinball balls, and through them onto this generators.
Do this 10 times and the achievement will pop up.
Good luck!
