In Chapter IX (9) you will come to an area where you will pick up a Riot Cannon. You will have to destroy all the Starscreams images and statues. There are 9 images/statues in total. There will be 2 golden statues in the area where you confront Starscream that for some reason you can not destroy, so don't worry about those. The achievement will unlock after you have completed the arena battle.
NOTE: For some the achievement did not unlock when they died in the arena.
Here is a great video walkthrough by NeedtoAchieve.
