In 2006, I participated in The Fall of Medusa V Campaign at my local GW Store (Novi, Michigan USA... which is now closed). As I remember, the campaign spanned several days/weekends. GW setup a website to track what WH40K race would control/destroy Medusa V.
So, my battle report will not be long. As I remember I was playing teams, me playing Tau, another Tau player, and some other Xenos race(s) vs. Space Marine/Imperial Guard, etc. It was the final battle to gain control of a drop ship to escape one of the Medusa V - Hydra Zone (USA) planets (I don't remember what objective/border it was) before it was destroyed in the Warp. Realizing the odds were against the Tau Empire collation being able to repel the Imperial assault and escape in the drop ship, we decided to destroy the ship and sacrifice our cadre for the greater good.
Many strategies were employed to distract the enemy while fellow Tau player used his 5 Piranhas with Fusion blasters to burn through the structure points and eventually destroy drop ship. Now, one move that I performed was to deploy my Pathfinder Squad to the top of a building for Markerlight sniping to support the other Tau units. They were delivered to the top of the building by their mandatory Devilfish... 12" move, the Pathfinders disembarked. Per 4th edition rules, exiting the Devilfish on top of a building after it had moved made the disembarking Pathfinders take a Dangerous Terrain Test. Unfortunately, I rolled a few ones and lost some Pathfinders.
After that battle, we were all asked to stay and have store winners declared, prizes distributed, etc. To my surprise, I was awarded a Medusa V medal of commendation of the "The Order of the Scarlet Wing". The store manager explained to me the Pathfinder losses I received in the airborne assault maneuver (via Devilfish) is why I received medal.
Here are the images of the award I received (names pixelated to protect the innocent
Finally, I'd be interested if any ATT members participated in Medusa V campaign and learn of battles/awards.
