The images below are storyboards by Rodolfo Damaggio who's worked on, among other films, Star Wars II: Attack of the Clones and Fantastic Four. He's currently working on Captain America: The First Avenger and Green Lantern. I find it interesting to see the beginnings of the suitcase armor (Mark V) that we see in Iron Man 2.
The scene is from Tony Stark's attack on the rebel camp. You can see more on his website.
