I think that's the route I'm going to go. That sounds like Raven Guard to me. Scouts to gather intel, Tactical Marines arrive via drop pod at the exact location needed (providing a distraction too), Assault marines strike their targets, and Shrike arrives with his wing wherever he's needed.
I think I'll go with this on Saturday. What's the worst that happens, I learn something?
Thanks for all your help, I'm sure I'll be back soon haha. Who knows, I might even post a bat rep on Sunday.
