My favorite battle for the cartoon would have to be the opening sequence to the movie. A ton of awesome fighting going one and plus in an awesome setting on and around the Statue of Liberty. And as for the comics, I've never really read that much but I thouroughly enjoyed the Cobra Civil War and the battles in it. They felt like real military large scale scuffles and there were some great tactical moves made by all sides. It was very enjoyable for me to get a hand on those comic packs and read all the stuff I missed out on.
