I'm about to have my group get into their first larger battle it's going to involve an assault on a formidible (but undermanned) chaos reaver held space port. The station itelf is situated inside a planetary right above a world experiancing nuclear winter from when the reavers conquored it. The next phase is going to involve assaulting a Harbour city.
My Captain has 5000 men under her comand more or less imperial gaurd with 100 of them counting as veterans. Shes paired up with a beaten up and undersupplied gaurd regiment of about 7000 gaurdsmen 50 tanks 650 storm troopers and a cruiser. She has a cruiser as well but the space station is heavily armed.
How should I play this battle? I really don't like the into the storm rules and I don't want to switch to a warhammer game (i dont think that could capture the scope of the whole fight). How have you run these sort of things before?
