During Gamescom Pete Murray and Tiffany Nagano were giving presentations showing combat in the modern age in Civ5. A (relatively low-quality unless you are registered with ESL TV) video of this presentation is now available.
It´s the same rather "preconstructed" game situation we were shown, but still interesting for anyone who hasn´t seen this part of the game, yet.
Since embedding doesn´t work with the ESL-TV player, go here to watch.
